The Stovebolt Site Forums The Shop Area Engine Shop Higher capacity oil pump in a 216

Well, I ran into a snag. The original pump uses a 1/2" OD inlet tube. Apparently the M29 pump used in the '53-'54 235's use a 9/16" inlet tube. If anyone can confirm that for me I would appreciate it. I ordered what I thought was a correct fitting, but I messed up on the thread size and wound up with the exact same sleeve style fitting that was on the original 1/2" inlet tube. Did a little casting around and found that a 1/2" flare fitting will screw into the M29 pump inlet, but need to figure out some way to connect the 1/2" OD tube to it. One place said the pump connection was a "bump tube" fitting that uses an o-ring seal. Those were apparently used for power steering pumps. I did find one of those but there was no way to connect the tube, as it was too long (if adapter to compression.)

One possibility is to find a 9/16" tube sleeve fitting (see the attached screen shot from the part listing) and some 9/16 tubing and sweat it to the 1/2" tube that the 216 uses.

Another option is to hit up one of my friends with a lathe and turn the flare fitting into one that uses a compression ferrule for the 1/2" tube.

Or try to find a power steering tube and adapt that to the 216 pickup connector.
