thedawnpatrol Posted March 29, 2016 Share Posted March 29, 2016 I'm just plumbing the fuel system on the Morris PU. I have noticed that there are two different threads used, on all the pipe ends, tank selector cock and fuel filter the mail threads are all the same, quite a course thread, however on the two outlets on the Autovac unit the threads are the same size but a finer thread? Is this the norm, or are the two outlets in my Autovac wrong ? ( this assembly was missing when I got the truck) Jules Quote Link to comment Share on other sites More sharing options...
Tony B Posted March 29, 2016 Share Posted March 29, 2016 (edited) Yes the second pipe is the induction pipe to create the vacum. Fuel goes from the bottom to the carb. Long time since I had anything to do with them, so can't remeber where the vacum is drawn from. Edited March 29, 2016 by Tony B Quote Link to comment Share on other sites More sharing options...

thedawnpatrol Posted March 30, 2016 Author Share Posted March 30, 2016 JULES the set up shown is correct and yes those two threads are finer than the others Thanks guys, yes, i think i know the set up, the top right pipe from the Autovac goes to the induction manifold, the top left to the fuel cock ( connected), then the bottom pipe from the Autovac goes to the fuel filter then the Carb. my problem is, i need one more fine threaded female connector to go on the induction pipe so it can screw onto the Autovac ? any ideas ? thanks for your help Jules Quote Link to comment Share on other sites More sharing options...
Tony B Posted March 30, 2016 Share Posted March 30, 2016 Try a plumbers supply place. BSP is often used on things like this. Quote Link to comment Share on other sites More sharing options...
