Two part question here.

First is last night my car would start but then quickly stalled. I have been running a Kenny Belle boost a pump and I think the stock fuel pump is shot. It's going to the local shop today to diagnose the problem. Whatever the problem I want to upgrade the fuel pump. I don't care what the pump cost as long as it will handle the 555 Hp it puts down and is easy to install.

Question 1) Any possible idea on why it's stalling?
Question 2) What would be a good pump for my 555 Hp.

Thanks in advance everyone.

I'm not an expert so I can't answer the why it stalled but I am using the ZL1 fuel pump in my boosted GT with no issues. I recently dynod over 600rwhp with no fueling issues. I believe the ZL1 pump is good to 650 rwhp but someone correct me if I'm wrong. My shop went through the back seat and added a g8only access panel for future pump changes. Very happy a year later.
