this might be a stupid question but i dont know too much about these pumps and what they need. so it says they need a regulator, i sont think it does but wondering if somebody knows for sure. here is the link for the pump. any help is appreciated. thanks Black Holley 140 GPH Electric Fuel Pump 10160 | eBay

 

Yes you do. You cant put very much pressure to a ve or the seals will say bye bye. I cant remember at this moment at what that pressure is but its not to high.

 

The Holley black puts out around 14-15psi. Just rite for ve. The seals in these pumps sent made for diesel fuel tho. So I don't know if it'll last.
