Old gas questions

halfafish said

My car pretty much sat for about 25 years. It might have moved around a bit on occasion, but not much. I know old gas turns into junk over time, so I got a new gas tank from AMD. A new fuel pump is an easy thing, but is it necessary to replace the hard line from the tank to the fuel pump, or is there a good way to maybe clean it out or pump something through it so I don't have to replace it? Replacing that line or bending a new one looks to be a PITA that I'd like to avoid if there's a viable alternative.

Don’t forget...While you are in there cleaning/replacing hard lines, I would strongly recommend replacing all old rubber R7 fuel hoses to GATES BARRICADE R9 fuel injection rubber hoses. The old R7 fuel hose can look fine on the outside but with the aggressive ethanol gas that we all have to use now, the inside of R7 is definitely degraded and bits of rubber can find it’s way into the carb/ fuel pump and cause PITA problems. Also I use ABA stainless steel rolled edge hose clamps( they don’t cut into the hose as you tighten it) for all my hose connections and they work great. My motto is do it right the first time and you won’t have to go back in again. Also as a added measure I use ethanol free gas and put StaBil Marine 360 in the gas tank as it removes any water molecules/corrosion in the tank and anywhere the fuel passes through. Hope this helps and good luck with your project.
