Hey guys this is my first suburban and it has a leak in a rubber fuel line and idk if it's the supply or return. It's rubber and only leaks while running. It's not officially mine just yet thinkin about tradin my ranger for it. It needs a water pump which he's providing all i have to do it change it out and now this fuel line. Good deal or no? Its got 163k miles on it and my ranger has 195000. Whats you're thoughts? Also i'm a newb here. Also has a hole in the rear barn door which isnt horrible just there. And the windows only work from the drivers door which i think i found the fix for that by jumping a blue wire from the lock switch to the yellow wire on the master switch.

 

has to be return operating psi on that truck is 55/60 psi koeo
