Is it ok to use teflon tape on a threaded fitting on a diesel intake line (before the lift pump)?

I would not if a small piece of the tape comes lose it could cause problems. General Motors stop using Telfon tape because it doesn't brake down if floating lose in a system.

Greg what to use
I would us something like #2 Permatex Or Non Hardening Sealant. Use very LITTLE!

THE ONLY WAY
According to the manufacturer's, You should be using copper "crush type" washers, now from experience, these washers, do work, but you have to be careful on how much torque is applied, or they'll, leak.

1996 Racor Manual says
"Pipe thread paste is recommended on port fitting connections. Do not use pipe tape- a loose piece could clog the system." 1996 RACOR 200R spin-on filter manual.

Leaking
There is a leak either at the copper washer (which I plan to replace) or some fitting that is threaded into another fitting connecting to the hose coming from the tank. It's a little hard to see exactly what is there. I am trying to have anything I might need ready so I only have to repair (and bleed the line) once.

Replace the washer.
Greg: I would recommend replacing the washer. These fittings should NOT leak and putting goop on them is just a temp. fix. I believe that you can also take one of these washers and heat it with a torch to get you by in a jam. Cannot imagine that this washer is going to be more than a buck or two.

One use washers
Some of the copper washers that are used on the Yanmars (and I suppose others) are one-use washers. Once tightened, the copper washer conforms to the shape of the fitting. Trying to reuse them is futile and you won't get a solid seal. Check with Yanmar. I bought a bag (10 pieces) of washers for the pressurized fuel line (banjo fitting) starting at the lift pump for $4.00 Now I have spares on board.

Teflon tape
Regarding Teflon tape use in fuel lines,one word: DON'T! A fuel-proof non-hardening sealer (A Pep Boys item) used sparingly in the threads, as someone recomemmended, is a temporary fix that worked for me.
