I cut mine off about 1/8 and then cleaned the edge up and it worked  fine.

If it's tapered pipe thread, cutting off the end probably won't help  

much. The taper determines how far the fitting will thread into the  

valve not the length. It probably won't hurt to try it. You might be  

able to find a shorter 90 degree fitting, there are some designed for  

tight places.

 hi list



 i want to cut off some of the threads on one of my 90

 degree fuel fitting exiting the fuel selector.

  i want to cut the end off the threads

 so that it screws all the way into the selector.

If you cut it off it will go in further.

I didn't catch the start of that thread - that sounds like very  painful advice!

  

 (sorry - I guess it's Brit. sense of humour!)

Hi John,



I have some good news and some bad news.



The pipe thread fittings should not bottom in the female 

threads.  Both male and female are tapered so the threads make a seal 

when the parts are screwed together.  This means cutting off some of 

the narrow portion of the male thread won't make any difference in 

how deep the male part goes.



The good news is the fittings are not expensive and are available in 

any hardware store.  So, you can give it a try and replace the part 

if you don't like the results.



Good luck,



Paul

hi list



i want to cut off some of the threads on one of my 90

degree fuel fitting exiting the fuel selector.  i am

making the center consul more narrow and the left tank

fuel line restricts the width of it if i want the fuel

lines to be hidden.  it looks like  there is about 3/8

of an inch of thread showing after installation in the

fuel selector.  i want to cut the end off the threads

so that it screws all the way into the selector.  it

looks like it is a little tappered so i am wondering

if cutting off the end will be a problem.

it would also be feasible to cut off the male and deepen the tapered pipe thread in the body. You might have to cut the tap off progressively as you deepen the female thread. Make very sure that you COMPLETELY remove ALL cuttings or chips. ALL of them...

You can cut the threads off, then you need to get a pipe die of the proper size and run it over the remaining threads. If you cot off three threads you should make about three turns of the die to get back where it was.

Hope that helps. just cutting off the end won't gain anything

Since it is a tapered fit, be careful as to not over challenge the material receiving the fitting. Screwing one in “Could” cause a crack if there is not enough material around the opening.
