1982 Brat on 1995 Blazer chassis with 1999 Suburban 5.7 engine....extensive floor and firewall mods! On second year of project.

I just did this with a 82 Brat. Cleaned the tank with oxalic acid and water. Took all the gunk from setting in a field 15 years but not the clogged fuel line. For that I cut a 10x10 hole in the top and reached in there and gently bent the fuel tube up far enough to get the screen off. It was caked on the outside but half full of some tar like gunk on the INSIDE. I sprayed it over and over with carb cleaner and soaked it with WD40 and gently scraped it with a pick. All the gunk clogging the fuel line was inside the tube where the intake screen is. From the outside I could only get a coat hangar and 8 inches before it hit a wall. But from my newly cut access hole I could shove a hangar in there where the clip was. Filled the tube with carb cleaner and soaked it overnight a couple of times and finally blew it out with 150 psi air. It was like a real thick tar. Can't figure out why it was all inside the screen? Welding the tank back was tricky. Set the wire welder as low as it would go and made hundreds of tiny welds, finally got it though. Not good news for you. You may take it to a radiator shop and get it boiled.
