Hi Everyone...
I'm having repeating trouble with a fuel line on my '71 multifuel deuce.
You know the fuel line in the engine compartment on the driver's side of
the engine that goes from the final filter outlet by the firewall into
the fuel viscosity compensator inlet? This is the fuel line that goes
along next to the steering shaft on a deuce multifuel.
Well, my truck has busted three of these lines since I've owned the
truck (in about 10,000 miles).
The last failure was in central California at 1 AM in the morning...no fun!
I have managed to get the line repaired and drive home each time this
line has failed, but I feel like I can't depend on this line anymore,
even when I install a brand new one.
I want to replace this stock line either with a commercially-made
steel-braided hydraulic line, or with simple barb fittings with some
high-quality fuel hose and double worm gear clamps so that if (when) it
does fail again in the field, I can at least replace the hose more
easily than I can with the original compression fittings and line.
Here are my questions:
1.) What is the darned thread size and threads per inch on these
fittings? It looks a lot like a 1/2" 20 TPI, but I tried that and it is
loose in the engine's inlet and outlet connections...it won't tighten.
I need to know the thread size before I can get the proper fitting,
otherwise I will have to take off the elbows and tap them to a standard
tapered NPT thread so I can use standard NPT fittings.
2.) This must me a common failure on deuces...what have you others
done to permanently fix the problem?
Thanks for any tips!
