Just a quick poll to see how people are using filters in their FI setup. I've seen a lot of people using no filter before the FI pump but I'm concerned that the pump runs very fine tolerances and might block up.

Comments welcome (even from CalvinX!)

Cheers

i say filter right after the tank, if any kind of sediment get through, best to remove it beofre it gets to any expensive parts of the system, like the pump. production cars seem to have pump inside the tak, but there must be some kind of gauze filter in there on the inlet to the pump i guess. My old carburettor mini had a gauze filter inside the tank

grr, i voted the 1st one, made a post, then it let me choose again, so i voted for the bottom one (can't have too many filters i guess. well, i suppose you can...)
but yeah, option 1 for me.

I voted Fuel Tank->Filter->Pump->Filter->Fuel Rail

Although what I've actually got is

Filter - > Fuel Pump (low pressure) - > Swirl Pot - > Fuel Pump (HP) - > Filter - > Fuel Rail

if you have an intank pump , it normally has some sort of filter on it , same for an external .

ideally you want the filter to be the last thing before the injectors , you really dont want those clogging up .

pumps are expendable !!!

my filter is after the pump , and so it is on road car .

I am going to use the a standard and freshly refurbished pump/regulator/filter assembly from a Vauxhall Cavalier 2.0li.
The pressure regulator is adjustable so it should give me some dial in with the Ford pinto injection system. Picture of unit on mounting braket below.

Just finished mine tonight.

Fuel tank - filter - HP fuel pump - filter - fuel rail

An an intank pre-filter is highly adviseable even with a carb setup.
