Measuring fuel pressure from clamp block

by Tom Delaney in 912 / 914 Technical Questions 11 years ago

I have a mechanical gauge and hose with NPT threads and I am looking for ideas/source for adapting to the metric threads found in the clamp block on the cross-over tube.

I would appreciate your help.

Thanks,

Tom

M10 is basically 3/8" NPT
See the chart. You can buy if you would like an M10 male to NPT on Ebay.

Thanks Roger!

The chart did the trick for me. I wasn't aware that 1/8 NPT has an o.d. of .405. Always learning :)

Just a note that Rotax and Diamond allow the use of 1/8NPT sensor into the fuel manifold M10 threads.
This is better than using an adaptor that introduces another failure point and more weight/arm=moment.
This has been confirmed by engineering.
