Bob, I remove the filler neck pipe to avoid metal shavings entering the
fuel system. Others coat their cutting tools in heavy grease and trap them.
I drill a small hole, then use a tapered punch to enlarge it to tap drill
size. Gives a bit more meat to tap for the bung. One could also braze a nut
onto the filler neck OFF OF THE COACH. JWID.

Thank you to Randy Van Winkle for his help with my installation, and ECM
efforts. Then there was Emery Stora, and Ken Henderson. And yes Randy. I
have a small leak were the fuel line is taped into the gas fill pipe. So
now I need to test drive Wed. Bob Dunahugh 78 Royale

Bob,

I picked up a conduit clamp at home depot that
fit tightly around the fill pipe. I coated the
area between the clamp and the fill pipe where I
was drilling the hole with JB Weld. Drilled and
tapped the area. The clamp offered a much thicker
area to tap into.

I got the idea from Bruce Hislop ( aka RF Burns ) and I think he
posted photos on the Motorhome photo site.
