fuel sender units

[marinemackay2003]

looking to sort a ph 1 fuel sender set up out for my car with fpr from a ph1 fuel rail

however i was a little confused with whats what

as there seems to be a few different set ups with the fuel senders

this is a ph1 set up ( 2 lines ) ^

this is whats in my car ( ph1 172 )

also 2 lines?



however i also think this is a ph 2 172 set up below, with single pipe

im confused guys they all seem different, can anyone tell me if my sender unit is a ph 1 with return

as need one for the supercharged build

cheers

the one at the top is my pic from somewhere. looks like yours has a return line not certain tho

 

[marinemackay2003]

yeah copied it from your thread

just a bit confused really as it has 2 lines, looks nothing like yours, but nothing like a ph 2

 

[tom172cup]

do you have two fuel lines attached to your fuel rail one at either end?

If you're going boost you'd be better of with a separate fpr rather than the ph1 unit so it can vary the fuel pressure with the boost.

As long as you have 2 lines on the sender you should be fine for a flow and return to the tank.

 

[marinemackay2003]

no i had a ph 2 fuel rail so no fpr at end, see this is what was confusing me a little

i would be better running a standalone, but this seems the cheaper option atm

i know cheaper is not always best, but will try this and see how it goes

 

[Cupman29]

I use a ph2 fuel rail with std alone fpr regulator. Very straight forward to do. Just tee of the for the fuel rail before the fpr and then the return goes from the regulator to the tank.

 

[marinemackay2003]

do you have any pics of the set up?

may have to look into it, however have bought a ph 1 fuel rail with fpr in end for now

 

[Cupman29]

The line going to the rail is just before the fpr. I used a brass tee.

 

[marinemackay2003]

that looks a fairly decent set up, i take it that its adjustable too?

 

[Cupman29]

Yeah, it's adjustable. Hose connects to the port on the top from the inlet manifold.
