My 57 3200 was bought with a 400 CI motor. The fuel pump just broke. The pump that broke had two 3/8" threads leading straight down out of the bottom of the pump. This allowed the supply and carb feed to basically take off in any direction. The pump had no identification on it and two part stores deemed it obsolete. Both suggested a stock 350/400 pump. These pumps have the carb feed pointing right at the motor mount. I have tried to bend 3/8" tubing close enough to the flare but it still hits the mount. I have tried to find a single brass 90° fitting to go from inverted flare to flare and the only thing found so far is two fittings mated which is too long and hits the mount. Is there a 350/400 pump that has the carb feed pointing down or straight forward? Is there a brass fitting I'm missing that will turn the carb feed up so it misses the mount? I do have the mounts that change the |6 to V8 but it just seems odd that of all the 360 degrees available to point the carb feed they chose right at the motor mount. Trying to stay stock (as much as possible) and not interested in electric or Summits polished aluminum with clockable in/out. Looking for a fix that will enable stock pumps to be swapped out in the future. Thanks in advance.

Are the pumps you’ve tried made to have a fitting screwed directly into them? Sounds like they are. My pump in my ‘76 Malibu had an elbow that a rubber hose slid over and got clamped in place. That was for the tank side and the carb side. I don’t recall which way the elbows faced, but I’m fairly certain neither pointed at the motor mount. You can always use a 90 degree fitting that you can screw a nipple fitting into, cut and bubble flare the fuel line from the tank and run a rubber hose run from the tank line to the nipple. That was the factory setup my Malibu had.

Yes my pump has a hose connection from the tank(pointing forward which is odd) and the carb feed is a 3/8" flare pointing towards the mount. I'm not that familiar with Chevy motors. Does the '76 in your Malibu still have the pump push rod? I have found better set ups but they are for later generation blocks with a cam riding on the pump. I have also found a marine application pump that still looks stock but the ports can be clocked around to a better position. I'm avoiding the hose up to the carb setups as it runs right next to the exhaust manifold. I would prefer a tube line.

Yes the pump in my Malibu ran off of a push rod actuated by an eccentric at the front of the cam. If the pump has a female port that you screw a fitting into you can make your own line that screws into the pump and takes an immediate bend just past the fitting and put a bubble flare on it to connect the hose to.
