Ok, I've got all the parts to install my fuel pressure guage (tapped banjo bolt, needle valve, flex line, isolator and guage).

I'm staring at the test port going into the injector pump and thinking that might be the easiest place to put the tapped banjo. Looks scary....book says 18 ft/lbs of torque...Do I use teflon tape on all brass fittings? Two washers with the banjo bolt. One on either side of the fuel line? Looks like I have to preassemble everything up to and including the isolator before mounting to keep from twisting the line. Am I going about this right?

no tape needed the washer will seal fine if torqued to spec.

Getting a torque wrench on that thing is a PIA. The way I did it was to install it and tighten it down. Start the truck and see if it leaks. If it leaks, tighten it slowly until it stops. If it doesn't leak, your good to go.

You're much better off using no teflon tape on the fuel system at all.
Problem with it is if anything ever needs taking apart the tape debris is almost impossible to completely remove from female fittings and can do a good job plugging up an injector.
I've used Permatex #2 on diesel fuel lines for years with great success. It's available at any auto parts store.
Use no sealer on banjo bolts.

Bigblue:

Where did you put the two washers? One either side of the fuel intake line banjo?

Thanks,

That's right Jay, one on each side of the banjo. I kinda wet mine with fuel and didn't wipe them off until I was through and checking for leaks.
Someone once said finger tight then add 1/4 turn...worked for me.
Snug down as necessary to stop any leaks.

Thanks Clunk.

I'll go to work on it this morning. Hopefully my guage mount will show today.
