Complicated fuel pipe
I am struggling to get my fuel lines in. Not the routing or the fitting, but all the ford fitted gismos. I had to get rid of my donor in a hurry and
left the (what I thought was) fuel pressure regulator and filter in place. The engine is a 2.0 inj pinto.
My understanding of the schematics is:
Fuel tank -> Fuel pump -> filter (all at the back of the car)---> (in the engine bay) Fuel vapour separator-> Fuel rail ->Pressure
regulator-> return pipe to the tank.
I dont have the filter from the rear of the car (I have one from an astra though) or the vapour separator - do I need the vapour separator? Its not
mentioned in the haynes manual or the autodata fuel injection manual.
Advice from anyone running injection would be very much appreciated

I haven't got a phote (there is a first), but it sits on the LHF inner wing just below the rear brake bias valve. Ally tank, just bigger than a
bean tin

So as thaqt's simpler that's what I'm going to do!

Always good idea to fit a pre and post pump filter. Injection pumps are prone to locking up due to the smallest bits of rubbish. I've not got a
vapour sepeator thingy. Mine is tank-filter-pump-filter-fuel rail-regulator-return to tank.

I did a bit of research today, it stops the fuel foaming so the injectors get pure fuel and not fuel and air mix.
I think that the standard filter mounted in the engine bay instead of the rear, mounted on end will do the same job - anyone comment?

my v6 cologne has a nice simple pipe from rear mounted efi pump to the injector fuel rail, and a return to the tank from the rail mounted pressure
regulator. No funny boxes, pipes, or whatever.

Mark, I have built three cars, two for competition use, which were fuel injected and I used the layout of (assuming you don't need to worry
about surge i.e. you have a catch pot built into the bottom of your tank)... tank - pump - filter - rail - regulator - return to tank.
Cheers
Nat.

That sounds great, I do have a swirl pot built into the tank which is also fed by the return. If I do get any problems with foaming fuel, I'll
know what to do!
Is there and advantage/disadvantage in having the filter in the engine bay or just after the pump?

Nothing major I think, only worry I would have about it in the engine bay is heat. The large filter is usually not quite full, which will then easily
give room for vapour if it gets hot, maybe a possibility of vapour locks? Never done it that way so I don't know!?

Sorry to hi-jack your post Mark.
If you change the 30/34 DFTH carb on a 2.0l Pinto (which uses a vapour seperator), for a 32/36 DGAV carb do you have to have to change the vapour
seperator to a fuel pressure regulator?
Hope someone can help as I'm totally confused.
Regards
David
