Thread: Fitted succesfully a extra Racor Fuel filter/ water seperator to a Puma fuel system

There was a tread covering this subject a couple of years back. And one of the things that came out of it was the restriction in the fuel lines causing problem with the PT/injection pump. I can’t remember the details, but I did research a Racor filter with a ‘priming pump’ on the filter housing with little to zero flow restriction. I’ll have to see if I can find the filter assembly details, post them up for ‘analyses’.

Update:

My preliminary line of investigation was/is heading down the road of the Racor 445R with the optional water sensor fitted. Available with 2, 10, and 30 micron filters, 170 LPH/45GPH, Max work pressure 30psi/207kpa. I like the idea of the integrated priming pump. Saves a lot of mucking about. At 24cm long it’s not a small unit. Around the $200 mark plus postage. Open for comments for and against? I am no expert on Land Rover fuel systems and I’d hate to give anyone a bum steer.

the 230 has a primer as well and low flow restriction

Found the Racor 230R (10 Micron) for $250 at Western Filters Online

Air Filters, Oil Filters, Fuel Filters & Filter Cleaning Services - Western Filters offers a range of Filter products for comprehensive coverage for on-highway, off-highway, construction, agricultural, industrial, genset, lift trucks and marine equip

Now I'll have to see if someone will be selling that armored housing to protect it in the 90's wheel arch...

The boat shop behind the fishing shop across from the shopping center has Racor filter/water traps for $90. Pat

I wouldnt bother with a prime pump model.its been a something that iv had to pull apart and clean.all the crud ends up in it.
something about these being reverse flow.

i like the look of the auto prime filters[racor] on transit van and other euro cars.they use a venturi idea.Stanadyne electric lift pump
but not at $400+ and a seporator bowl at the bottom thats an addon deal.

I purchesd many years ago a unit to suit a 13 liter truck.i fitted the shortest fuel filter last time as they never need replacing when on a 2 liter engine.i recently saw another version that had to be stripped down to replace the filter--it had about a dozen bolts around the top.

on our bomag roller with deutz engine it has a rebranded racor unit the elements about 350-450mm tall.these are better than other filters.

Hi Sashadidi , Gouldier here from Dayboro , I would like to see some photos of your pre filter and guard
Thanks

On page two of this thread:
Fitted succesfully a extra Racor Fuel filter/ water seperator to a Puma fuel system

Hope I may revive the thread.
I see that fitting a pre-filter can be done and has been done, but not very often.
I am still unsure about some points:

The pre-filter will be put in-line before the original filter. There are two fuel lines betwenn it and the tank. One wil be feed and the other return, but how do I know which is which?

What size need to be the hose-end-fittings (nipples/barbs) ? (Inner diameter of the fuel lines).

And can the original fuel lines simply cut and the hose-end-fitting just pushed in and secured by a jubilee clip ? Or is any specific hydraulic fitting (cutting ring i.e) needed or preferred ?

Would it make sense to buy a pre-filter which has a heating element in it, just in case for very cold climates ? Or is this useless as the original filter has no individual heater anyway ?
(I know that heated Diesel returning from the fuel rail is mixed to the "fres" Diesel temperature related - so if the engine is warm no Diesel "freezing" (that paraffine thing) will occur, but to get there the engine will have to be started first and running a while).

Flow rate of 170l/h is ok, understood that. As for the filtration - there are 5, 10 or 30micron spin on filters available. I think that 5um makes no sense as is simpley leads to a doubled main filter. Could as well stay with just one filter and relace it twices as often. But what of the alternatives is best used ?
Is there any adverse effect in any way to the flow rate?
