Fuel lines
 

I have to replace my fuel lines on my 2000 Jimmy SLT, Should I use steel or nylon allso the gas gage shows full all the time, should I change the sending unit.
Any Help would be grate!

the sending unit might be bad and i say use that same type of lines on your truck right now .

any ways GL

Thanks for that, I just saw the nylon lines at UAP and was not sure if they would be better. Gas pours out of the top of the tank when it's running, lines probably rusted out from sitting just like many of the others that I have all ready replaced.

if your gonna use rubber make sure you get the right one for fuel unless they gonna burst with pressure or the gas is gonna chew the rubber also
