There are plenty of places out there that sell mechanical pumps made for NASCAR. NASCAR doesn't allow electric pumps for safety reasons, so companies take hipo fuel pumps and rework them. If a 750horse engine running 8000-9000rpms doesn't have fuel problems, you wont either. These pumps sell in the 80.00 range, so they really aren't any more than a good pump. I have one of these on my car, and haven't had any problems.
