big exhaust pipe!
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.
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

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?
My one was done in New Zealand, I know they had to get special ferules made especially made as the pipe size is not the same as the fittings and the Puma system must be airtight .
here are the specifications including pressure drop which is very small, used this setup for a year now as has another guy here, no problems with fuel system at all.

Hope this helps you
They used a racor 230r 10 micron as pre filter then LR original filter . As I posted in Defender 2 and here it saved me a lot of money
