95 fuel setup

[SUpracliPse86]

Ok this is my first post, I have a 95 420a with the fpr on the end of the fuel rail. The car is turboed and im leaning out once i enter boost. I only want to get up to about 8 psi outta this car nothing crazy...So what would be the best fuel setup for me.

Do you have FMU or SFMU?

My original setup had a 12:1 FMU and a Wally 255fp. That's all you need for 8lbs.
When I built the motor I went with a SFMU, 750 injectors and MegaSquirt. I did have to modify the rail to cut out the FPR when going that route, but not needed to do with the FMU and stock injector setup

Ok...I have the FMU. Ill have to pick up the 255 pump tho...Another question i have is ....Does the FMU tie in just the same as a AFPR?

So you're running the car with the stock fuel pump? Don't boost at all then. Hell I wouldn't even drive it at all until you get the FP.

"Tie in" meaning installed? Not 100% sure how the AFPR gets installed, but would assume that it's in the return line just like the FMU.

An FMU is a rising rate pressure regulator, you use it insted of the factory one. Some people leave the factory one and put it inline with the outlet from the fuel rail, that makes the stock one redundant and useless, but its a simple install that way.

Ok thanks guys..I know exactly what i need to do now.

Do i need a missing link with this setup?

No missing link needed on a 95. ECU has no with boost.
