    I've never seen one like that on a Chevy. The arm is wrong to bolt it on, unfortunately.

    My son used a "Professional Products" fuel pump for 2 years before it failed and nothing I could do would repair it. Sorry but I bought one of the knock off intakes for a circle track engine and it performed great. We used it on Dart heads and it needed very little work to port match. It was a case of $$$'s as a Dart intake was over double the price and on a comparison dyno only gained a few HP.

    I was told to get one for a 59 Chevy, but I still knocked my frames.

    Got a 32 chassis pinched for Model A. Third pump I tried fit. It’s the one @squirrel posted in the beginning of the thread. It’s a carter 4685. Just fits[​IMG]

    ^^^^^^^^^^ Thx for that Carter # I also am running a '32 frame pinched for an "A" body and a Holley pump wouldn't clear the frame. Do you have any idea what the pressure output of that pump is? I'm running 2 Edel 4bbls and it sure would be nice to get rid of that noisy ass electric pump and all the necessary plumbing along with the fuel pressure regulator:cool::)

    Is it a Brookville? Mine is, pinched too much !
    There’s a M before that part number. It’s described as a muscle car pump on Summit’s site, so I don’t think you will have a problem with pressure.

    I expect the pressure/volume out put of the stock pump shown is just fine for a pair of 4bbls on a mild small block.

    It is if you call or they will tell you who handles them.

    OK Jim ( @squirrel ) called CARQUEST first and they confirmed that while their site showed it for SBC is indeed for Cummins diesel and do not know why it came up on a search for SBC.

    Also called Summit they said that they no longer handle the pump but that Race Pumps no longer manufactured it and it was a quick fuel product. They referred me to Jegs who said that it is no longer available.

    Dino 64: Yes it was ordered as a rolling chassis from Brookville by a previous owner who never finished it, and the engine wouldn't even go down in the frame onto the mounts with a Holley pump installed.
    Jim: Although it isn't a "mild" small block, I'm not too concerned about insufficient output, but rather that since the carbs are Edelbrock, they are not at all tolerant of pressures much above 4-5 psi, and it would be nice to get rid of all the extraneous hardware and plumbing required for a decent pressure regulator:)
    Beaner: Yeah, at least you tried;)

    I run a fair amount of pressure on dual AFB setups, and they seem to do fine. But every car is different.

    Summit site was down earlier today, but is now back up Carter #4685 shows max pressure of 7 psi and free flow of 45 gph. Several people in the reviews claim to be running them on AFBs and Edels w/o regulator & w/o problems. Tempted to install one and try it, as I'm not at all a fan of electric fuel pumps on street cars.
    Wouldn't really be too much work to do a quickie install, leaving the electric pump in place,but off and a bit of fuel hose for a temp setup, bypassing the regulator, and if OK, then go back and do it right. Worth considering:)

    I'm under the impression if you don't pinch a 32 frame when using a 28-9 body it looks like s--t.

    ^^^^^ Mine's a 30-31, and even it wouldn't look right without a pinch in front and a tuck in the back to match the wheel well. But they continued on inwards or something cause it's quite narrow up front. Also has an "A" front crossmember, but I'venever measured it against a stock "A" front crossmember,.

    I'm sure it's a personal thing but even the deuce on deuce looks better when pinched when built as a hiboy.
    3/4" (per side) eliminates that unsightly gap between the hood sides and frame rail nearest the grill shell.
