I'm thinking my fuel tank is fuel of crud. before I got the jeep the PO let it sit for about 5 years. once I get a chance to drop the tank and verify what is the best way to flush the tank out?

older cjs and engines dont like additives, esp ethanol, take off top fuel line crank engine, see if fuel comes out, ck if coming out past fuel filter , now big thing if carb has filter in line check it too, cjs need to have all carbs tuned, and clean, others parts to this problem could be the air lines i had to change out charcoal canister and most all air lines ck for cracks even the smallest crack can screw with carb i also put regulator in line i think fuel line runs 5-7 psi with carter carb its not so critical other carbs seem to need it hope this helped i also have to clean carb about every 2500 miles just cus of fuel we have here colorado, a good carb cleaner seems to work good change filter too aleast 2 times a year

check your fuel lines where they change from rubber to steel ( that connection is above the fuel tank ). I had the same symptons that you explained and found that i was sucking in air at that connection. Quick fix was putting 2 small hose clamps on it. 2 years and the problem has not came back.
