Looking for recommendations on an external mount electric fuel pump.
Street/Strip car, low 11s, dual Edelbrock 500s. Carter 120 gph 4-12 psi ain’t cutting it.
1/2”lines, 3/8 pick up For what its worth.
67 RO23 clone with 6.1 SRT Hemi and dual quads. Soon to have Drag Pak induction and Throttle body.

A friends Max wedge stick shift stock eliminator car went 10.50's with only 3/8 lines and a Holley blue pump. Why would you have 1/2 inch outlet and only 3/8 inlet? Depending on how hard your car leaves it is fighting that head pressure. Any fuel pump with an adjustable out put pressure of about 18 psi will work make your inlet at least 1/2. regulate the pressure at the carbs to no more than 6 psi. On my Stock eliminator car I have #10 inlet and #8 outlet pump regulated to 20psi with bypass and 3 psi at 6 pack carbs with 3/8 lines. Volume is more important than pressure. I run an Aeromotive pump.

Mal , That pump should be enough . I went low 6.50s (1/8)with a silver Carter . I do agree you may be needing a 1/2" pickup , unless you sump the tank . I would prefer a 1/ 2" or -10 outlet from tank when running 1/2" line . I run Aeromotive A750 pump , have a Holley black(140) for spare . Tex

I would think that Anything that’ll move 120 gph should be plenty for the HP range you’re in. First thing I’d do is go to a 1/2” pickup. It’s a “weakest link” deal. I got one off ebay, worked great for me, although I’ve since gone to a cell.
More food for thought: a couple of years ago, I was running 1/2” hardline. All was well until one day when it wasn’t. I couldn’t figure it out.... eventually went to -8 braided line. Problem solved. Never did figure out WHY, but I haven’t had a problem since. I pressure tested the hardline I pulled, tested fine (????). I run a Carter 4600HP electric leading to a 4862 mechanical. Seems to be working for me, I see 5+ psi out the back door.

We regularly run low 11's @ 3650 lbs. with nothing more than a Carter street/strip pump and 5/16" pickup and fuel line from tank to pump. The same one this originally slant 6 car was born with. The line from the pump to carb is 3/8"
Actually it's run 10.01 @ 133 with this setup but with a supplemental electric pump/tank on the ntrous solenoid.

OK , Thanks for the info. I’m going to run a pressure test with a temporary pressure gauge and see what it shows.

Funny you should mention needles and seats - I had a light bulb moment last night - remembered when I bought the new carbs, I forgot to swap in the hi flow seats! Ive been running the .093th instead of .110th seats.....which has gotta not be helping! 🤦♂️🤦♂️🤦♂️

I agree with the others that your current pump should be adequate for your combo, but if you do decide to upgrade, you cant go wrong with a Mallory 140 / holley black pump... if you want to make absolute sure you have enough pump to feed it.
