Engine bay fuel line routing

[Steven A Schiltz]

Hi y'all got a stupid question ( if you'd consider it) but I know these cars are much different but when I look at mine it kinda doesn't make since ( by previous owner set up ) so my understanding is the fuel feed (from the rail) is on the driver side and the fuel return is on the passenger side (4g63t) so my question is what im saying is it backwards because on my car the fpr( have a fuel lab one) is linked in on the driver side and the fuel filter is on the passenger side. Is this correct? Iv always known fuel filter to be in the feed side.

I found my answer tryed to delete post but couldn't figure out how

The answer, in case anyway is wondering, is that you can feed the rail from either side.

Hi, thanks for the reply I was also asking myself the same question

As some have said. The fuel rail is not directional you can feed it from either side.

I run mine "backwards" for a rail mounted regulator. Works well

 

[Steven A Schiltz]

I may try that. I was just more curious that the fuel filter was on the return side and not the feed side hahah

You still seem confused. Stock feed is passenger side and the fuel filter is on the feed side.

It's probly because I work on Ford's for a living so it just look backwards to me

There fuel filter is on the line from the tank to the rail

Yes, on the Turbo cars the pump feeds the filter then into the fuel rail and the FPR on the other end dumps what it doesn't need to maintain pressure in the rail down the return line to the tank.

I seem to remember the NA 2G's with 420A's use a regulator back by the tank and single feed line to the engine. But it's late and I might be confusing cars.

You would be correct about the 420A fuel line.

Ok Steve that makes more sense to me
