Vping - if the pump works, consider mounting it under the car near the fuel tank and plumb it in line with the standard pump. Wire it and the stock pump to power through a single pole, double throw switch so you have a permanently mounted back up pump. The Auto Pump is a bit over pressure to use in place of the standard low pressure pump (the Auto Pump puts out around 4 psi or better). It will work fine in a pinch as Tony stated.
