Fuel Pressure Regulator Connection & Mounting Edelbrock AVS2

[Some Car Guy]

I thought that factory used a smaller return than the feed. I’ll have to double check.

I would skip the regulator if possible. I doubt you will have issues as the edelbrock pump is supposed to be the same one as one of the carters. I ran the eddy pump with no regulator since it was rated at 6psi and it never gave me an issue so I never checked the psi it put out. Could be different in the era of private equity though.

The booster design, venturi position, & emulsion hole positions in the emulsion tubes are determined by the carb company.....& the appropriate fuel level to give the correct mixture strength. Final result of all this is the carb company providing the float level adjustment to provide the correct mixture ratio. If you raise the fuel level via float adjustment, you richen the calibration...& vice versa. You do NOT increase the fuel level in the bowls to maintain mixture ratio. You provide adequately sized n/seats for THAT engine, & a fuel delivery system [ pump & lines etc ] that can deliver enough fuel to the carb with some reserve capacity. D. Vizard claims that a change in fuel level of 0.100" is worth about one main jet size.

Still hoping one of you has a good photo of a clean looking regulator install for the AVS2 carb in our cars (bonus for including a Performer RPM intake).

If you decide to do it before, not after, this is where I mounted mine. One is a return, the other a dead head. At first glance, you don't even see them. Obviously, the orange car isn't together yet.
Good luck!

those both look like CLEAN installs. I like that 270 degree fitting! Thanks.
Which car is the deadhead setup and which is the return style? At first glance I suspected the orange car has the return - if so, I would love to see the line connection at the pump that comes from the regulator.

Don’t have a picture with an AVS.

When I’ve done mine, I have found that the Russell and/or Earl’s catalogs helpful in generating ideas with their fitting options. Maybe look there for ideas.
