54 gmc... Newb Project

[99 to Life]

you should get atleast 20mpg average. more highway. I was getting around 20mpg in my carbed vortec sbc on highway. So how you like the PSI harness? they seem to be a popular choice.

Lastly I'm on my second late 80's 2wd blazer tank. its 20g and fits in just like the stang tanks, but.... the fill is to the driverside, so you need to locate the fill either through side of bed or fender. I chose right behind fender so you can hardly notice its there. The sending unit is cheap for it, and I suppose you could just run an out of tank HP fuel pump if you use it for the LS stuff. just a future thought, if you don't do a cell.
