I was tightening the fuel vent fitting to the vent line inside the tank to 120 inch pounds...(tag on Vans screen pickup tube says 110-130 inch pounds) and just for reference a marked a dot on the flats where I started torquing after getting it finger tight. (I got the fitting to 120 inch pounds, but it took about 1.25 turns of the nut...about 450 degrees rotation)...
Now I'm looking at this information on a chart that someone posted here that if you dont have a torque wrench available it is ok to finger tight the nut and then mark the flats and for a #4 fitting (1/4" tubing) rotate the nut about 1.5 to 1.75 flats.
Now something seems out of wack here. I rotated that thing about seven flats...It did seem fairly tight to me, but I dont have any experience with this tubing stuff.
I double checked my math on the torque wrench extension formulae.
I didnt use any lube on the fittings at all. I dont see anything anywhere where it says to put lube on the fittings, but I see some on this site do.
I would think that if I lubed them, I would get more rotation.
Can someone shed some light here for me please?
Has anyone noticed this also?
Please help.
