hot air fuel rail question

[the wrath]

i need a fuel rail for a 85 gn will a 84 rail fit? and i wanted to know what other rails would fit this car?

 

[novaderrik]

yes, and 84 will fit. i think they might even be the same all the way up to 87, and also on the 89 Turbo trans Am. possibly even in the fwd LeSabers and park Avenues from the late 80's, too.

Just the 84 and 85 will work. The 86-87 LC2 fuel rail will bolt on but the Schrader valve will hit the back of the alternator. 84-85 valve points up.86-87 and others valve points straight out.

Don't tell my 84 that the 86 fuel rail on it
won't fit, it might get upset. Yes, the valve is close
but it doesn't hit on my car.

86-87 fits, but the schraeder valve is actually close to the coilpack, not the alternator. You will need a 90 degree fitting to be able to hook up a fuel gauge to it.

Right you are. It's been way too long since I worked on a HA.

It's a PITA trying to fit a gauge or hose when using the wrong year of rail with that coil pack in the way. I used to swap rails on my cars only because I was too lazy to take 5 minutes and swap injectors. You waste 5 minutes in one area to save 5 minutes in another.

Before you pull the turbo off the car be sure to soak the exhaust inlet pipe bolts as well as the downpipe bolts in WD-40 or a similar product a few days beforehand. You will be glad you did!
