Re: 68 camaro help, no fuel?
I would check the hoses front and rear for cracks first. The pump is going to try to pull the easiest thing it can, and air is easier than fuel. The pick-up tube prefilter may be plugged in the tank, Maybe someone put something in your tank, or it might be decades of dirt. The mechanical pump is a real reliable item on the engine and is so easy to change compared to the intank pumps on todays cars. If you have a vacuum gauge connect it to the inlet side of the pump. Start the engine and you should see 10-15 inches of vacuum and it should hold when you stop the engine. If it falls off either you have a bad gauge connection or a weak pump. Last one I got from my AC Delco jobber came in around $18.50 in the box. Good luck!!
