I have an old OEM fuel line from pump to carb and really want to use it. I want to run something through it or soak in something to make sure its clean. any suggestions? thx,john.

In my case I let mine soak in a pan of carb cleaner which acts as a cleaning agent for a few hours then ran soap/water and finally water through it to clean on the inside.
Then once dry I took 0000 steel wool and good ole windex or white vinegar which acts as a lubricant and a mild acidic cleaning agent to clean,shine and remove oxidation on the outside. Do not let it sit in straight vinegar for more than a few minutes if thats what you use as it will react with the metal in a bad way.
Finally spray bombed with a clear of my choice which happened to be Walmart/Krylon gloss clear. it has not yellowed as of yet.

I took carb cleaner sprayed it in the line, then used some silica sand put some in one end, then used my compressor and blew it out. Did this 3/4 times. Worked for me. Just make sure you get all the silica out.
The line was off the car, I would not do this while it's on the car, be way to messy

When I bought my 71 Bronco it had been sitting for 10 years, three gas tanks, I pulled all 3 tanks and had them cleaned, I used carb cleaner which I sprayed into fuel lines and blew out with air, been on road 10 years now, I did install 2 fuel filters, one before pump amd one at carb. Jay

The vinegar idea is a good one. Then flush with carb or brake clean.
