On my 85 GSL?

Need to see if a fuel line swap is gonna be needed?

 

5/16's metric equivalent. at least that is the hose and filter size i get.

 

I'm pretty sure it's 5/16th's for the main line and 1/4 for the return. I remember reading somewhere that RICERACING is running the stock lines on his 500hp beast so I don't know if you need to upgrade. Just make sure you have a big enough pump.

 

and there's no rust in the lines..........don't ask......

 

Mike, I dunno if this will help..

I will be running one new 10AN line from the pump to the injectors, and I will be using the current stock fuel line as the new return line. This is a way to guarantee flow at all times, since I am not positive of the inside conditions of the 17 year old lines.

Maybe I am just playing safe, but I don't want to blow the motor on a varicose fuel line.

 

Ok guys thanks, Directfreak your right, but If I run AN fittings with hoses all the way im looking at a shitload...


Ive tested the lines by allowing the pump to push some gas through it into a bucket and the lines look perfect, no **** in the bucket...

Any objections to a Bosch 300 lph/40 psi pump? Might throw a fuel pressure guage on there just for safe keeping especially during its early times in the car and during tuning...

 

just get some 5/16 hard line and bend it yourself or if you cant find 5/16 use 3/8 and strech the hose over it. thats what i did works fine so far
