fuel system refresh

[peanut84]

hello peoples

a few weeks to go untill i take my land rover out on its first trip since i brought it and rebuilt the motor (well stepe dad rebuilt it, but i helped a little).
Now i just doing all the little things here and there to whip it into shape eg: a little wiring for a cd player and speakers, uhf, some 12v power points in the rear, driving lights and so on.

Now i am about to REFRESH the fuel system, i want to replace all rubber fuel lines from the 2 tanks to the carbies, the fuel pump (as the one on there is ticking very loud and is all rusted) and all the little hose clamps that go with it all.
Now my questions are:

1. what fuel pump should i replace the old one with? i read something about a VN commo pump that works?

2. what size fuel hose should i use and should it be EFI hose? (even though its a carbie motor)

3. should i get a fuel pressure regulator so not to flood the carbies, even though excess fuel is pumped back into the tanks?

any help would be awsome!

Hi peanut,

So what are we working on here? 2 tanks, carbies? (more than 1). Need more info to be able to help.

okie dokie here goes.

its a 83 model series 3, LWB, 3.5ltr V8, twin stromberg carbies. it has the factory fuel tank above the rear diff and years and years ago grandad put a 2nd tank in under the drivers seat. and when i had a look under there yesterday i noticed all the rubber fuel hose from both tanks to the fuel pump and from the pump to the carbies are very dry and slight cracking here and there. so i decided to replace all the hosing, then i noticed the rusty external fuel pump and i want to replace that as well.


ummm i think thats it

[disconut]

Right, I'm sure the forum owners of these things will be able to offer great advice. I'm a bit too modern, (despite the appearance of my ride). :)

you dont need efi hose as you wont have anywhere near that amount of pressure.....

just use normal fuel hose.....can be bought by the metre......the diameter you need will depend on
the fittings it will be fitted to......if they are all the same then you will only need the one size hose.....

if any of the hoses have any bends in them such as 90 degree bends....
you may need to buy the genuine bit of hose as bending hose that much may kink it and stop fuel flow.....

hose clamps......get the size you need for the diameter hose you get.....


just work out how many clamps you need and how many meters of hose....
take a piece of the old hose with you so they can match up the inside diameter if you are not sure.....

and watch you dont get fuel in your eyes as the hose comes off.....its not fun....

[peanut84]

ok cool sounds good.

only one thing left and that is the fuel pump, can you help me here?

G'day Peanut84 :)
You should be able to get the fuel hose from any Repco or similar good quality Spare Parts supplier, it is sold by the meter and is called standard fuel hose and has a woven ply in it and is usually clearly marked as fuel hose, from memory the Series Vehicles fuel lines were either 1/4 inch or 5/16 inch (take a small sample);) The Fuel pump sounds like the double ended Electric one that was the original fit on 6 cylinder series 2a/3's they usually tick loudly when building up fuel pressure,(pumping), they then stop and only repump (tick) when the fuel pressure drops as the carbies use the fuel, they can get a very poor outer appearance but work quite well, if it is working OK I would just clean and repaint the outside and see how it goes, make sure that the electrical conections are good and clean, and that it is clean at the mounting point as that tis the earth return, it is usually poor earths that stop these pumps, if there is any air leaks in the fuel hose that type of pump will be very prone to it and they will just pump air, (ticking, pumping constantly with poor fuel delivery at the hose end. :(

hope that is of some help.

i havent seen the pump off one of these.....but some of the old electric pumps were serviceable......
you could replace the contact points and the rubber diaphragm......

if yours is like one of those pumps.....go ahead and refresh that as well....and keep the old parts in your spares box.....

[peanut84]

hello uncleho

well the pump is a metal cube looking thing, and fuel goes in the top and out the bottom. then a wire that goes off to where ever it goes.

i though about cleaning the old pump up, but when it comes to maintaince on anything i own i am very fussy and just prefer to replace rather then try and fix it up. if you know what i mean. and because my first trip in the rover is to yuleba (4 1/2 hours away from bris) i dont want to take the chance.

i saw this on ebay and thought it might be ok

Genuine Bosh 0580 454 001 fuel pump, this is an intank fuel pump and is a universal fit for many vehicles inlcuding mercedes, bmw, mazda, toyota, mitsubishi, honda, with 38mm diameter.


thats not what you are after......plus its an efi pump.....too much pressure for you and your fuel lines.....

[peanut84]

Hi Guys
From what little info Peanut passed on I think we are talking a Stage1 V8.
More info Peanut please.
Are you a young bloke who has inherited a project???
If so,and it is a Stage1 well done,they are pretty rare.Basicaly they are a crossbred Series3 Landrover mated with a Rangerover.You will see the difference as the grille is flush with the edge of the bonnet,instead of recessed between the front gaurds.
A series3 but having the Rangie V8,gearbox,constant 4X4 and front CV equipped diff,the Series leaf springs were retained.Not long after the coil springs from the Rangie were adapted in the County,the birth of the Defender.
Peanut let us know if it is a Stage 1 as the advise will be quite different.
All the best
Andrew

hi landyandy
you are so very right.

i am young - 21
inerited - yes with small cash ajustment
stage 1 - i assume so, as the grill is flush with the front guards as u stated.
constant 4x4 - yes and diff lock
cv equipped diff - dont know what that is
leaf springs - yes

i will post up some pics as soon as i get some so u can see for yourself.

whoops

my bad

[PhilipA]

No, you do not want one of those. That is a high pressure pump for injection.
You need a low pressure pump for carbs.
The one Rover uses is a "Facet" pump and if yours ticks it probably is one. But its not a cube, it is a cylinder about 10CM long. there should be a Bayonet fitting on one end. This is to open the pump to clean the filter.
They last for years and years , and the best you can do is get another one , if you are looking for reliability.

G'day Peanut84 :)
It does sound like you have a Stage 1 V8 model, I.E. Series 3 Landrover factory fitted with the Rover 3.5 litre V8 and the LT-95 G/box and transfer, that was the 1st stage of the upgrade to the Coil Sprung Landrover in 1983 UK,(110) The second fuel pump that you listed is suitable for fitting to it, or any other carburetted vehicle in replacement of the mechanical one, I have just looked up my Series 3 V8 parts book and they only list 2 types of fuel pump and they are both listed as being for the 2.6 ltre six, they are SU pump complete AZX 1500 (genuine No) and Bendix Pump, the bendix pump is around one with 2 bolt bracket type mounting,to a support plate by 2 rubber insulated bolts, the pump has an inlet pipe and an outlet pipe with the electrical feed in the centre between the pipes, the second type of Bosch pump would be the type if replacing, From memory on the Bendix,there is a hexagon end cover, UNDER THAT IS THE FILTER, remove it and clean the filter;) a good wash with petrol or a carby cleaner type product will do, The SU pump has a gauze filter, they were both nice little earners for the Service Dept (Cleaning Filters) THE PUMP NEEDED REPLACING SIR! that will be $$$$ thank you :eek: Dealers --Stealers,:rolleyes: different Company Name same tricks :(

If it is of any help to you the Aussie Carbies were different to the UK ones, to suit our ADR's the part No 's LH== ERC 4702 & RH==ERC-4703 and the RH carb had a heat shield, Distributor Part No was ERC 4823 complete (lucas)

I also recall that there was some interchangeability of the F/pumps with the early Rangie, but I am not sure, a Rangie owner would know.

Hope that helps, if you need anything more let me know.

[peanut84]

thanks for the help guys

here are some pics for you to look at so you can get a better idea what im on about.

[DEFENDERZOOK]

the pump in the pics looks like a simple ashdown pump......
very common on lots of early vehicles from the seventies which had carby and electric pump.....

it was an off the shelf replacement electric fuel pump which was fitted to anything......
mosty as a replacement pump cos the genuine was too expensive.....

[peanut84]

alright i will go to repco and autopro 2moz and sus out what pumps they have and how much before i think about buying the 2nd pump i listed of ebay.

will keep you posted

dan

[DEFENDERZOOK]

i used to have a few laying around the place when i had the mazdas......
there may still be one left downstairs somewhere.....if i havent thrown it out.....

go to your nearest wrecker and just get a second hand one....throw it in your toolbox....and forget it.....
the part you carry a spare for never breaks......

[PhilipA]

That looks like an electronic "Facet" to me.
I am pretty sure its not original.
Just google "Facet Pump" and you will see what the pump should look like.
I am also pretty sure a stage 111 would have had the same pump as a Range Rover the same age IE a "Facet" or maybe they were also called Bendix but now they are certainly called Facet.
The originals are not that expensive at $155 on one site I saw in WA.

G'day Peanut84 :)
As Zook says that looks like an "Ashdown" unit they were a common fitment during the 70's-80's they are asian copies of the Facet Pumps, as most of the English /US/ European makes as the "trade incentives" (Import Duty) favoured the Asian nations, so it is today, If you do go Facet pump you would need to use a 3.5-5.5 psi range unit like the SS501or2 or STS 504 or 476087-K kit, but I would try REPCO/Bursen first :)

[peanut84]

rang repco and auto pro and the both have no idea about "facet fuel pumps"

but i did find this. I think it might be the go joe.
