Here's some nice torque wrench formulas to keep on hand.

With any added extension to the length of the torque wrench, you will add torque to the hardware when set at the original setting. So if you set for 135 in/lbs, with a crowsfoot added to the end, the resultant torque would be higher.

 

I had similar issues and used some nose savers to cure leaks. Nose savers are thin pieces of soft aluminum that fit over the tip of the male AN fitting. Your local AN vendor should carry these. It's very unlikely that you over under tightening your fittings as they do not require much torque.

 

I have never heard of these. I tried a search for them but came up empty. Do they go by any other name?

 

Alternate Tightening Method Two
The second alternate method of tightening is very simple and
easy to remember. Bring the nut to hand tight and then rotate a
quarter of a turn. This applies to all sizes. Mark the fitting as
indicated in the flat method to confirm the quarter turn.

 

This is the method I use.

Earl's conical washers

If you can't find them let me know. Mine are made by Earl's.

Look for conical washers or seals for AN fittings. Summit Racing has them.

I found them, thanks! It's nice to know those are out there. They could come in handy later once I get to the point of moving fluids through all the lines I have run.

Crowsfoot wrenches

I just happened to have these in my tool box from way back when. They work perfectly for my aluminum fittings and appear to hold better than a standard open end style wrench.

Still not completely comfortable with the torque specs. I posted as they do not seem to coincide with the flat and a half method. I guess somewhere in between is about right.
