Fuel Leak, Rusted Lines & Lift Pump
Hey all. So living here in NJ my truck has a fair amount of surface rust & grime underneath. I replaced the brake lines with a full SS set a few years back and knew the fuel lines would go soon as they are all corroded.
Filled my truck up Tuesday and found a nice puddle in the driveway (1 gallon maybe) on Weds morning. Looked like it was leaking from the top of the tank somewhere.
I also have a FASS lift pump system I got last year and never installed in my garage. But now that I am leaking I have a few questions
1- Does the rubber supply/return hose in the FASS kit replace the fuel lines from the engine back to the braided lines on the tank, or is it just enough hose for the pump install. Lines-to-go has the pre-bent SS lines but I don't want to buy them if I can use the FASS hose for the whole run.
2- I am thinking it is my sending unit, gasket, or braided tank hoses from the tank to the exposed fuel lines. If I need to remove the bed or drop the tank, and expect to find everything rusted, I just want to do it all now. Lines to go has SS braided lines that I could go with. Just want to confirm that would be pretty much "everything" as it relates to the fuel system under the truck and no longer have to worry about corrosion. And is there a "better" option for the sending unit or just get an OEM replacement.
Anything else to consider while I do this? I don't want to do a sump kit, but I heard some people add valves on the lift pump?
Any other tricks, tools, knowledge?
