You should always mount an electric pump BELOW the fuel tank normal fluid level. They do not like to suck as much as push.

I tried mounting a pump up above the axle in front of the tank but no matter what i did, could not get that pump to prime and pull fuel. I moved the pump to the inside of the pass frame rail next to the tank and a bit lower, and instant prime. But, i have a friend that mounted it up there and has no problems. Mine are 68 and 73 b-bodies.

I mount mine on the shock cross member just ahead of the sender/pick-up. Have done that on several cars over the decades and the one on the Cuda now has been there for 15 years or so. And since my cars are street cars I don't want to hear that pump. So I mount it on a piece of rubber. Usually a piece cut out of a tire. Lasts forever that way and really knocks down the noise.

I have my Holley pump right in front of my stock gas tank by the sending unit above the rear diff. Its not lower then the tank as its actually even with it or near the top of the tank. Its not many places to mount it lower then the stock tank. It pulled fuel instantly and has never ben a problem running in the 10's with a 3/8 line. I will say whenever I install a new electric pump I always put a bit of engine oil in the pump so it does not start dry and helps it seal well when first pulling fuel into it. I have never had a problem with the Holly pump mounted like that. Ron

I'm going to install a Carter P4594 electric fuel pump and want to know where you guys put it. I'm looking for any pictures of a 70 B Body with a Dana 60. I'm thinking about just above the fuel sending unit but want to see some pics. thanks. I made a metal shield to help keep stones away mounting outside of frame shown in this pic.

There are a few brands of electric pumps that will effectively lift fuel from above the tank. Most will not, and or will cavitate if mounted that way. Less is more when it comes to lifting fuel above tank level. I use a 2 speed Fuel Labs pump mounted at the top of my tank hooked to a pair of Holley Hydramats.. The high speed switch kicks on when the secondaries open using a micro switch. The pump runs at a cooler low speed on the primaries

What he said! Same deal used a holly Blue Pump and Fram filter and housing. Drag race and street drove that thing for close to 10 years it had no issues!

I put one right in front of the passenger side spring hanger, easy access and worked good for ages.
