Hi
Installing an electric Holley blue fuel pump part no 12-802-1 and regulator with no return 3/8
braided line on my 66 . I'm sure it's been done before but will I require a lift pump or surge
tank
Cheers Ed

I'm sure you know the drill that these things are meant to be installed close as possible to the tank and no higher than the fuel outlet as they are 'push' rather than 'pull' pumps.
I have a similar setup on my '69 and it works OK with no return line or surge tank. Fuel inlet to the pump is a few cm above the tank outlet but hasn't caused any issues.

Thanks heaps BAC
Sounds like I have mine plumbed up much the same
as yours , I've also installed an Earls 100 micron filter between the tank
and pump also a 40 micron between pump and carby and reg near the Carby as they recommend , now have wiring left

You'll also need some ear muffs :lol:

They threw in a set with the pump :grin:

The Holley blue pump will be ok but mount it at the rear and with rubber mounts . If running a Holley carb set the reg at 6 to 6.5 psi tops . A return line is best but will require a different regulator . Might pay to run a filter before the pump and another one before the carb . Do not run E10 . I think the Holley reg is pre set to that psi anyway .

Thanks mate , yes that where it's mounted and filters are in
I'm running a BG demon 650 double pumper . I will try setting
it to around 6.5 psi and see how that goes
Cheers Ed

I've been through all this. I first had a Mallory pump and regulator mounted in the engine bay and would always end up with vapor lock. In the end I got my self a cheap Carter fuel pump & mounted it next to the fuel tank outside of the cabin area and works great. I'm running a high spec 428cj motor with a 830cfm nascar carb and never lean out or run the bowls low on long flat out runs with 4.11 gears.
