DuoWing Posted October 11, 2012 Share Posted October 11, 2012 I've been using a bosch 044 inline fuel pump in my attempt to get a quieter pump and get rid of my fuel problems. One issue I can't seem to get rid of is the fact that I cannot get it to seal on the inlet. I ordered the metric to hose barb adapters for the pump. The inlet is 18mm x 1.25 I believe. Anyway it came with an aluminum washer that I cannot seem to get to seal. I tried an o-ring that came with the 18mm x 1.5 oil drain plug from the auto parts store. This seemed to work, but is already leaking as I think it's deteriorating. My outlet is fine, but I'm using the brass/copper or whatever it was crush washer that the pump came with. Anyone have any suggestions where I can get a washer/ring/seal that will work? Should the aluminum one work, maybe I'm not tightening it enough?

SleeperZ Posted October 11, 2012 Share Posted October 11, 2012 I've been able to seal these by sanding the washers smooth with emery cloth or very fine grit sand paper. Also do this for the brass fitting. You don't want to over-tighten it, just tight enough to form the washer. Quote Link to comment Share on other sites More sharing options...

DuoWing Posted October 13, 2012 Author Share Posted October 13, 2012 Thanks guys I appreciate it. I feel dumb for posting, I always forget about McMaster-Carr yet I've ordered so much from them. Quote Link to comment Share on other sites More sharing options...
