what is the differance between a 2wd and a 4x4 fuel rail ,as i have a 4x4 plenum on my 2wd and there seems to be no fixing on one,of the bolts that goes into the plenum from the fuel rail

 

I think you've answered your own question.

Apart from different regulator fixing, they differ in their mounting onto the plenum.

With the 4x4 plenum, use the 4x4 fuel rail and regulator, and fuel feed pipe, or get a lug welded to the plenum and use the 2wd rail.

 

The 2wd just uses a longer bolt that passes all the way through the plenum and out the other side, the little bracket that goes ont he 2wd reg then bolts on here.
Just get a 4wd reg.

i fitted the 2wd rail on my 4x4 cover by making a litle bracket for one end of the rail IIRC.

 

thanks guys , is it better to get a 4x4 fuel rail with the fuel reg built in or seprate?? cheers gary

 

Whatever is easier for you.
