Dan,
You might try the Holly Blue Pump. I have had one on since 96 and never had a problem, but that doesn't mean they won't fail. My only problem was I had to replace the pressure gauge as it started showing 4 pounds whether the engine was running or not. I messed up by trying to adjust for it and when I put the new gauge on and started the car I had 15 pounds pressure. Shut it opff immediately and adjusted back down to the 7 - 9 pounds they recommend.
