I did a major overhaul to my 94... . had the block torn down to block and pistons. I did a injection pump, cam, head twins etc. So the fuel was "dry". I have pushed the primer button till I got blisters, then I got a broom handle and pushed more. I can not get any fuel in the pump that I know of. I dont hear any thing at all. The truck is a level, I was thinking about jacking the rear a bit to see if that would help? Do I just need to keep pushing?
