i recently bought a AAM return fuel system. i dont have the instructions and bought $90 worth of parts from altered atmosphere to finish the kit and i cant find and they dont have instuctions for it. Does anyone have a DIY for this system or another fuel return system so i can compare things and figure it out with a relative help. lol Thanks

 

sorry buddy but the aam fuel system is a one off piece they made one fore the guy u bought it from and for drax on here....sorry no diy on it

 

yeah, i have it on my car. out the box, it is not a good kit really. it provides a custom fuel rail, and a rising fuel pressure regulator and gauge, but it has some serious short comings.

1. it should have an intank fuel pump.
2. it should have a plug for the bleeder valve in the fuel line that bleeds excess fuel pressure back into the gas tank.
3. using it as it is, i hit the wall in fuel delivery at 10 psi. was kind of disapointed.

but with the addition of a warlboro fuel pump and plugging the bleeder valve, things are much better.

 

maybe this might help you? might be a similar install.

Im not sure what the AAM system comes with but to do a detailed DIY for everyone especially those not mechanically inclined is gonna be so long.. I was gonna do a DIY on the ptuning fuel return but I just ended up with a review for 2 major reason. 1. Its gonna be a very long writeup if you have to describe each step. 2. I dont want to make a short/summarized DIY, it might end up to be missing info for the newbie and potentially cause injury, damage and possibly fatal. But you can consult the toyota repair manual as far as disassembly and putting it back together
