Pump above water level - Primer pump needed?

[Richard L]

Are you putting the pump in the engine bay? The aquatec pump can prime from 3 feet up.


Aquatec states that:

POSITIVE INLET PRESSURE WILL INCREASE THE DISCHARGE PRESSURE BY A SIMILAR
AMOUNT, FOR A GIVEN FLOW. MAXIMUM INLET PRESSURE IS 60 PSI.

I cannot see how this can possibly work. the bypass pressure is set by a loaded spring. one end of the spring is at atmosphere pressure. Increasing the inlet pressure won't alter the outlet pressure.

If you are concerned about the reliability of the pump, follow the guideline and put the pump in the trunk. Did you read any of the warning in the box?
