problem with fuel pump
ok so a few years ago I had a 383 stroker installed and I went from my efi to carb. I kept the stock fuel pump and had a fuel pressure regulator installed. My car ran good for about a year and then it wouldn't start had my mechanic shop do a run over and fuel pump was bad so I had it replaced, just figured the stock pump finally decided to crap out. Well a couple of weeks ago I was driving and my car just stopped running I costed to a stop and thought I had run out of gas (I also noticed that I was leaking a little bit of oil) so I had my car towed to my mechanic and they have been working on it on the side since its a buddies shop. Anyways got a call today and they said that my new fuel pump has burned up and they think that the regulator has been causing the in-tank pump to be over worked. This is the first issue they are going to tackle before they look into the oil leak( I think I also blew a rear main seal). So they ordered a new pump to replace it and I think they mentioned going to a aftermarket pump meant for carbed engines. So has anyone ever had this problem? Any advice?

Re: problem with fuel pump
What fuel pressure regulator did you use?
If it's the standard $30 dead-head regulator, yes, you burned up your pump. You need a return-type regulator; they cost more, but less than replacing the fuel pump on a regular basis.
There's nothing wrong with the in-tank pump. I would NOT recommend using an "aftermarket pump meant for carbed engines". A Walbro 255 is a much-used replacement pump. It too needs a return-type regulator.

no return = dead pump
