My '86 245 that I have been chasing a stumbling/hesitation problem has finally characterized itself. I gave up and took it to a specialty shop yesterday (actually had no choice - car kept on dying on the way home from work and I couldn't chance it dying in heavy interstate driving). Anyways, it turned out that crud in my fuel tank was killing my main-fuel pump and it the engine was getting intermittent pressure. When the tech installed a new pump, he said it oozed a mixture of fuel and crud that was the consistency of molasses. He will sell me a known good tank for $50.00 and I have the option of installing it myself or paying him $100 to install. I have had the in-tank pump and sending unit out before, so that part is familiar to me. Are there any other gotchas to doing the tank myself, such as getting the filler tube loose from the tank or fishing it out between the axle and exhaust. Or is $100 a bargain for the PITA that it could turn out to be. I would really like to do it myself as I need to save the $100 if possible, but I also don't spend 16 hours doing it either.

Thanks,
Lance
