Dat73z Posted July 7, 2015 Share Posted July 7, 2015 Does anyone have any idea what size threads the tapered fittings on the factory mechanical fuel pump are? Is this a common fitting that can be purchased off the shelf? I've attached a picture of the fitting in question. Thanks! Quote Link to comment Share on other sites More sharing options...
Tony D Posted July 10, 2015 Share Posted July 10, 2015 They're all over Asia. They are not NPT, they are JIS/Metric Quote Link to comment Share on other sites More sharing options...
Dat73z Posted July 10, 2015 Author Share Posted July 10, 2015 Thanks Tony, attempted measuring against NPT tables earlier in the week with no result so that makes sense. Any idea of the JIS/Metric size? Otherwise will attempt once I wrap up the work week here and report back with a size. Quote Link to comment Share on other sites More sharing options...
takayuki Posted July 11, 2015 Share Posted July 11, 2015 Most likely 1\8" British pipe thread. Just like the oil pressure sending units Quote Link to comment Share on other sites More sharing options...
Dat73z Posted July 13, 2015 Author Share Posted July 13, 2015 Thank you takayuki, it was indeed 1/8 BSPT. Quote Link to comment Share on other sites More sharing options...
Pac_Man Posted July 13, 2015 Share Posted July 13, 2015 For the record, JIS is the same as BSPT. Quote Link to comment Share on other sites More sharing options...
