bbc mech fuel pump
 

what are you guys running ?,

I'm running the Holley 130 with regulator.

are they marines?with the vent? or car pumps

fuel pumps buy race pump with there reg only 15 lb push rod pressure and the simplest install I have ever done (fittings on top not bottom) and has the most flow I have seen http://www.racepumps.com/index.html

I also ran a bleed off # return to tank line they said I did not need it but I liked the idea of cooler fuel and I seem to worry about the ethinol seperating from the gas this may help stir it up but I have no facts just what I here at the ramp and parts store

That looks sweet.

But I do not see a outlet for the vent tube?

There's no diaphragm so there's no need for one. The diaphragm is like a balloon- it can't have pressure on the atmosphere side or it won't pump- so, it needs a vent. The only reason the vent tube is required bu USCG is if the diaphragm ruptures, the fuel will be contained. If a seal failed inside of a positive displacement pump, fuel wouldn't leak.

Example- USCG listed electric fuel pumps don't have vents.

Have for sale Holley 170 gph.
Currently use the new Holley black billet pumps:
