[TR7 Modifications and upgrades]

I need help. My mechanical pump wasn’t working so I bought a small 2.5 to 4 psi electric pump. And put it in line where the mechanical one was. That didn’t work so I put it in the trunk where the filter is and that didn’t work. No fuel is coming out of the pump. And I’m not trying to drop the tank to figure it out because I don’t really want to disassemble the rear end to get the damn thing out. Anyone have any ideas I’m missing? 

[What should I expect?]

I’m picking up a 79 tr7 later this week it’s a project and I don’t know what kind of issues to expect from it. Anyone have any advice?
