no teflon on Mallory 4309??
I noticed when I got my AFPR from MAllory, it said not to use teflon tape to eal the threads. Can anyone tell me why? Im getting leaks from 2 of the ports, and I cant stop them. I originally used thread sealer, the same thing I used on my freeze plugs and head bolts, but I cant get it to seal properly. Can I use teflone on the regulator, or should I completly stay away from it?

Im thinkin they're just thinkin some people would overdue it, and the teflon would get into the regulator. I dont think a little would hurt, just enough to seal it. I gotta get these lines sealed asap!

Not sure about the teflon tape part, probably they figure it could either blow out or come off and clog something, not sure. I used the thread sealer by Permatex and it works fine for me.

well, other than this, I havent had any problems out of it. I mean, its a universal part, so they cant expect everyone to use AN lines. They gotta think of people, like me, who are on a budget for the time being and can jsut use barbed NPT fittings and rubber hoses.
Screw it, I put a little teflon on it. Worse case scenario itll f**k up the regulator (which is rebuildable), or screw up the carb (which Im replacing with a 650 DP soon). Either way, I dont see how teflon is going to interfere with the fuel delivery or regulator as long as it isnt protruding into the lines/flares, whatever the case may be.

Shreds of teflon tape can come loose and find their way into inconvenient places. Liquid teflon or some other fuel safe thread sealer is a better idea.

I used teflon tape made for sealing gas lines. I got it at Lowes. It is yellow and slightly more expensive. I couldn't get anything else to seal. Don't put it on the first few threads and you shouldn't have any problems with it clogging anything.

I think Mallory replaced the 4309, with the 4307-M... it's supposed to be much better. Lemme see if I can find a link for ya.
Here ya go;

With the engine off and pump on, I can get a consistent 5.5psi. Anything over that the gauge starts jumping. With the engine on, I can get it a little over 6psi. Im using the stock return and feed hard lines with 3/8 rubber hoses connected to the regulator. I know i know, trashy lookin, but its workin for me now, and it IS only temporary.
So far the teflon tape seems to be working. I can it last night for a little bit trying to get the timing right, and it didnt leak once. But only time will tell. By then hopefully Ill have all new AN lines.
