[Healeys] Leaky Banjo Fittings at Carbs

[rct2bnc at aol.com]

Bob,
I think that SU fittings are Whitworth size wrench sizes...not 13/16". And you can strip out the threads in the cast fuel bowl lids.

Are the washers brown or black? I believe the brown ones are the 
original type and the black ones are being proffered by some suppliers 
and may be slightly undersized. I usually, if I think of it, soak them 
in WD-40 for an hour or so before installing, and re-torque them after a 
day or so because they do take a set. I torque them 'elbow-tight*' with 
a 13/16" half-inch socket and wrench (fits the bolt head well). It would 
be difficult, but not impossible to strip the threads on a banjo fitting 
as they're coarse (you'd likely strip the carb or pump threads, not the 
bolt).

* Torque settings : finger-tight, wrist-tight, elbow-tight, 
shoulder-tight and all-you-got tight.
