Engine/Transmission (1998.5 - 2002) FASS install

[woodsrat]

took this on by myself today just to prove i could do it. my mechanics got a good laugh most of the day. would not suggest doing this outside takes longer than i had planned. anyone how has done this install where did you run fuel pressure from?? was told it ran from the pump but have no instructions. also how do you set pressure have seen people on here as high as 18psi at idle andas low as 10psi. and 10 before i bought fass but could pull it down to 2 at wot would like to stay above 10 at wot.



thanks in advance.

The fass kit I bought from ADT included a fitting to connect a fuel pressure sensor into the line running up to the injector pump. My pump makes about 18 psi but i am having a little problem with pressure fluctuations. Sometimes it will bounce back and forth between 14 and 18psi. I think it might be a partially plugged pickup in the tank. I plan to pull it next week and have a look. I also would like to know if and how the pressure can be adjusted.

I screwed the fuel pressure sender right into the fass unit there is a 1/8 npt hole near the top. If you take the fitting out where the return line comes out you will find a spring a ball. longer spring == more pressure.
