Great tips from you all!
I'm taking my time on this.........cleaned up the hanger bolts and straps today with a wire wheel, then priming and re-undercoating all of it. The tank looks really clean, but there are some spots on top that have exposed metal. I think it's galvanized, so it's not near to rusting, but I'll probably prime/paint the topside anyway. Rock chips wont get up there, so I'll save the undercoating for the bottom side. The tank must have been entirely drained, because it's so clean, and took 3 gallons of gas to budge it above "E". So I'll pour out the remaining gas, then flush it once more with some acetone. I know that many will then use a hose to flush again, but I don't think it's necessary, and don't want to wait for the tank to dry out. As for the pickup tube, yes the sock is staying off, but I'll bend the tube to help extend it, then see if it might be extended a bit more with a brass compression fitting. Then a clear filter before the pump. I have enough vehicles already that require crawling around in the dirt for a simple filter change! The car did sit for 4 years, but with the low mileage and drained tank, hopefully there is no sludge like Cat's. None I can see from the two holes, anyway.
