Think my fuel pump is dying...

[DarkoNova]

Car's been sitting for a couple years at the body shop.

It still starts and runs but doesn't run right. I don't think it's fuel related because there's a lot of valve chatter. I need to pull the valve cover to inspect but that's a different story.

I've got a clear inline fuel filter between the carb and pump and I distinctly remember it being at least half full when I used to drive the car.

Now there's barely anything in it while it's running.



I was going to get a new pump because they're not that expensive, but a co-worker is making me have my doubts. I was going to get a $50 summit pump that puts out 110 gph but he's saying it will be too much and I should just go to AutoZone and get a $20 ac delco pump.

The engine is supposed to have roughly 450 hp, but I haven't dyno'd it yet. I planned to get it running well enough and then get it Dyno tuned.

Thoughts?
