so is 1/2" feed enough- Aeromotive guy wants to see 5/8 but the choke point is the fitting on the tank- what's everyone else doing with bigger power?

Kirk,
I'd like to see it. My pump was higher than what you described. I am fixing to mount the new stuff this weekend and sure would like to see what others suggest.

That's where I'm going, maybe an inch or two lower. I'm going to run it off the merc pump wires which are/were tucked out of the way on the harness. I need to drill a hole in the bulkhead for the return line, got a white plastic fitting to clean it up, will go same level as feed but just off center for easy access to the tank fittings. Fuel pressure gage comes in tomorrow- going to put the hour meter in the engine compartment rather than punch a new hole.

Hey Cat & 650 I guess your not able to use bolts if your below the floor on the bulk head ?

I seems as if my original system was to high. I do know it never had any issues. The boat ran and won P5 several times and never starved for fuel.

too high is relative- I'm just anal from my rockcrawling, seen a lot of pumps killed cause of no head (bad for a marriage too).

Theoretically, once the electric pump is wet it is happy and will have a kind life. It's dry starts that are bad so you want in a valley sort of where it's always wet.

I'm using #12 or 14 1" stainless screws- the assy does not weigh that much- I'll keep an eye for loosening. You could thru bolt but you'd have to trim away the foam between the tank and the bulkhead thru the 6" access hole and it would be a pain at best. If the screws dont work I'm going well nuts which effectively thru bolts it and shock mounts it at the same time
