I wanted to go fuel injection on my '70 Malibu. So I purchased a complete system. NOW I'm have a ton of trouble trying to fit the frame mounted fuel pump. Source says to have the pump as close to the tank as possible AND low as it starts out as gravity feed. Well, that's just not happening. After installing and modifying the pump level and location twice (now on the third location) I woke up at 2 am realizing that the location is right where the exhaust must go over the axle tube. I'm guessing that I need to go "in tank".
Commendations as to using oem tank and fitting an in-tank pump or replacing the whole tank. I can't be the only person out there that has gone through this. As this is the weekend, I'll have to wait until Monday to ask the manufacture WTH?

If you do a search in the Performance Forum sub forum EFI you will find multiple answers to your situation.

I too will set my car up with EFI. This is the pump I will be using:

Holley Sniper EFI 12-373 Holley EFI Fuel Tank Modules - 350 LPH - 1968-1972 GM A-Body Vehicles

This in-tank fuel pump module is a high-pressure unit that flows 350 liters per hour (LPH) and is capable of supporting electronic fuel injection (EFI) engines producing up to 750 horsepower. Featuring a pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for this...

I've been down this road. Get an in-tank pump setup. I've had a Tanks Inc tank for 11 years now. I'm very satisfied and would highly recommend it. That was after trying several external pumps.

You want a baffled tank with baffled pickup area for FI. Tanks inc tanks have it.

I will be installing this soon.

Some of the baffled tanks have a so called catch area for the return fuel to keep the hotter fuel and air from the reentry from being too close to the pick up.
There is a nostalgic racer near me that I know that can do that.
Check out some of the small tire mustangs.

Holley Hydramat for non baffled tank....I don't have experience with this product, but IF I was going to use stock tank, something I'd look into

to reiterate what one pro does on EFI conversion is to ALWAYS use a new baffled tank, pump in-tank. It becomes the K.I.S.S. solution.

Well, I went K.I.S.S. and purchased a new efi/baffled tank from TANKSINC. The pump area is recessed with two holes machined in with threaded screw holes. It also has the front corners trimmed for exhaust oversized pipes to have room to go through. Powder coated in a silver looks good too. Installation of the pump and gauge equipment was educational, but I survived it with a few new words added to my vocabulary. Their techs on the phone were very beneficial. The shallow 7" deep tank needs a mod for the gauge assembly as well for the pump. Hopefully, today I'll get the tank in and run the hoses to and from the front end. On a side note, my neighbor and friend is doing the same thing on a '67 Ford F100 (coyote engine/trans, LTD front suspension, rear Explorer axle assembly. The tank and hoses are from the same outfits.
