Hi guys,

Just curious about something if a person already has a bypass regulator (EFI model) all setup and plumbed can you add a dead head type regulator after it to knock the pressure down to carb acceptable levels? I have a Magnafuel 625 pump with 8 and 10 an lines.

You can do it ,but why? If you have to buy a deadhead. Why not just buy the correct regulator. And sell the other one to get some of your money back. Just a suggestion.

Ordered an Aeromotive 13204 problem solved. Was just curious, and I'm keeping the other regulator if I ever pop this engine I'm going injected and turbo.

Personally i'm not a fan of the big efi pumps used on carby setups even with the return regulators. Just seem to heat the fuel

Many low pressure pumps out there that work well

What would you recommend ?

magnafuel 275 with the built it bypass return for deadhead regulator setups. I recently put one on my 67 and it solved my fuel pressure drop and vapor locking issues completely. Jmo tho

Nothing wrong with an EFI pump as long as it isn't too large. You need to look at a pump curve and see what flow rate the pump will produce at the pressure you are running it. Even a low pressure pump adds unnecessary noise and heats if it is too large. That magna fuel pump you have is a monster.

Walbro is making a 400 lph EFI pump that flows right around 100 gph at carb pressures. Suppose to be super quiet and relatively cheap. I keep wanting to mod my tank to run an internal pump. The external 140 gph Mallory i'm running now is too big and too loud.
