I have a Holley blue pump right now that’s mounted just about even with my sending unit and I hear like a hammering type noise coming out of the regulator the tank is full they say that it has to be lower, however, does that mean below the sending unit I was told those pumps need to be gravity fed
My holley blue pump is within 4 in from the sending unit

This is the pump I'm going to try on my next street motor build. https://walbrofuelpumps.com/frb-13.htmlI'm going to use a return system with an Aeromotive regulator, all for a simple Carter carb. Expensive, yes, but it should work and be reliable and long lasting. 3/8" supply and return lines.

I mount my electric fuel pumps using a stock type Mopar gas tank with a stock fuel pickup on inside of the passenger side rear subframe in front of the rear end so the pump inlet is at the same height as the bottom of the gas tank Works good, last a long time

Pumps work better pushing fuel, a long time ago before I had a brain there were two different cars with same problem. First was our 68 dart Hemi with the x ram, it ran 10.31 but was popping above 6000, second car a 69 mustang with a Roush 588 inch shotgun motor twin dominators (840 hp) was popping on top end too (8.90-153) couldn’t figure it out till another racer said “you ain’t got no gas” both had ONE Holly blue pushing from rear tank. This was long before the BIG pumps came out. Like I said brain fade. Before I could get two pumps on, the ford blew and Hemi was sold. Anyway mount in back or below tank (within reason) you’ll have no trouble I can beat that brain fart I think years ago built a model A coupe with a SB 307, before beating me up, money was EXTREMELY tight and the motor came with the project. I did a backyard rebuild complete with a PERFORMANCE RE-GRIND on the stock cam ( Big bucks there LOL) I scrounged together a tri-power setup and used the VW gas tank that was already mounted. It ran 13.50's at Fremont falling on it's face near the top of second It later dawned on me that the outlet on the VW tank used 1/4 inch hose BUT nipple / off valve it connected to had a much smaller ID DUH!!!!!
