Electric Fuel Pumps
On another thread kens64 mentioned he was running an electric fuel pump. I am using a Carter electric unit, forget the model number, but it puts out 8 psi. It was too much pressure so intalled inline is a Spector adjustable regulator set at 3.5 or 4.0 psi. I was just wondering what other electric pumps people were using and how they liked them. My unit sure is noisy when it is first turned on, but it gets drowned out with the two glasspacks. It seems to me that the 8 psi Carter always being regulated to 4 or less will be prone to early failure. Mike

An edit note on the above post. The pump is pushing gas to a 600 CFM Holley on top of my 292, which is an estimated 250 HP. This note is to let you all know I am talking about y-blocks with electric external fuel pumps, as opposed to the stock type y-block eccentric driven fuel pumps.

54efffie, that is encouraging. Sometimes it seems like I invent things to worry about.
Janet, my understanding is that the pressure issue is not with the 292 but the carburetor. Too high a pressure and gas will flood out the carb pushing past the float seat.

Mine is a Holley pump, not sure what model number. Its from a Pro-Jection system I had on it for awhile. I changed back to a carb because the computer went bad, and just kept the pump hooked up.
I was sure the pressure would be way too high, due to it being setup for fuel injection, but it ran great.

I looked for the box, and can't find it, and i noticed under the cab, they are the red big holley pumps, and had forgotten i also put a fuel pump in front of it also and put fusable links on both, they are big pumps and are red, and i paid right at 100 dollars a peice on them too... I remember they were the 7 lbs plus types when i bought them though, maybe i can find that darned box, and im also using that 2bbl motorcraft carburetor 2bbl on both these 292'2,(just the ones they used on thosse early 197o'2 302 engines), si i know it works good 46Y and ive gone on trips and everything and never had trouble....Janet

Thanks all for the information and replies. There probably are not too many of us with the external pump. The only reason I installed mine was due to the eccentric driven pump interfering with the front motor mount.

I know mine work just great, and i get good gas mileage....But i plan to put a togo switch on mine just in case i ever stall, and may even install a fuel pressure reducer, who knows, my MPG may increase, all i can say is with my holley set, i have absolutely no afterburn from my exhaust, and she runs cool too....Janet
