Mechanical vs. electric fuel pump?

Mad...

I'm pretty skeptical about those numbers that Carter claims...That small body and 172 [email protected] lbs seems really optimistic.
The big 6 valve Alcohol pumps have a body twice the size of those 4862 style carter pumps and they flow those kinda numbers that carter claims 172 gph.We just gave up using the 6 valve pumps and went with belt driven pumps.
When ever we got the volume/flow up to a TRUE 120 plus GPH a bypass or return line was needed.
It's been a long time since I've had to play with a mechanical pump but the amount of fuel that I got out of them with my test rig was no where close to the claimed numbers at the time.
The 120 gph out of a stock style carter pump as mentioned above just reinforced what I found out years ago...very very optimistic claims.
But hey...if it works for you that's all that matters
