Holley is going to be featuring myself and the Firebird in an ad campaign.
I'm currently on a 4150 HP 750cfm 4bbl double pumper.

Part of the arrangement will include a transition to Holley Avenger EFI 550-401.


My vehicle has the basic mechanical fuel pump and no return line. Vechicle suffers from lots of starvation issues (primarily from being at rest, hot or cold) - evaporation as well a the fuel backing down a bit too far... hot fuel line temps... etc. (Long turnover times as fuel takes a while to get to the carb after sitting for a while cold, or sitting for a short while hot)

I had been considering the 73 455 SD fuel pump & adding a return line.

I'm now going EFI. I am now open to the idea of an electric fuel pump.

I like the fact that it can force the fuel forward without cranking, as well as it being a bit easier to route the fuel line away from hot engine components.


If you have EFI, or were going EFI - would you be considering an electric fuel pump?
Would you plan to have a fuel pressure regulator?
Where would you mount the pump? (I've seen it in the trunk as well as hidden in body panels)
Would a return line be appropriate for this config w/electric fuel pump?

Thank you for not flaming me
