1928357 is the SN for realoem comparison if needed,

This is a picture of my fuel pump in tank. i also have the exterior (2-pump system)
as well as a type of expansion tank behind my rear passenger wheelwell.

Ok.

Red: That line goes to the other half of the tank.
Black: That goes to the expansion tank in the wheel well.
Blue: Goes to the fuel pump.
Green/purple: Thoes are for the EVAP system. They work with the charcole canister.

I think that the hose marked red above is the return from the FPR in the engine bay.

YOUR GUYS ARE AWESOME!!!!

no wonder gas came out the big hose when i tested like in the bentley.

i had the red hose plugged and put the guage on its nipple HAHA .

When this happened, fuel spewed from the FPR location, since that hose was clogged, and no fuel was returning to the tank.


Awesome, Thanks

Not on mine. Unless his is different, but we both have 87s.

im pretty sure red is return from the FPR side. the little metal hose at the bottom connects the two tanks.

When i plugged the red hose, fuel spewed from the return side of the fpr, meaning it couldnt go anywhere else except past the hose clamp.

after building up there, it came out the fuel pump supply side of it all. until i yelled to remove the switch from the relay!
