fuel tank return line
needed a #8 fitting in fuel tank for my return, was told to drill & tap the sending unit, which I did, but not enough room between edge of tank anr elec part of sender, could get fitting in sender but hits tank, it's #8 w/3/8NPT on tank side..what have anybody else done for a setup like this ? thanks Rob

I make a setup similar to a sending unit. I use about a 2" hole saw and cut it out of a sheet of 1/8" aluminum. It will have a pilot hole in the center of the circle you just cut out. I open that hole up to the size of a #6 (#8 in your case) bulkhead fitting. I actually use a bulkhead fitting designed for fuel cells. It is a high flow fitting with teflon washers to seal it. I install that fitting in the center of my round plate. Drill 4 mounting holes around it. I then drill about a 1" hole in the tank (it's just larger than the OD of the bulkhead fitting) Then, using some self tapping SS screws, you mount it to the tank. I use a little piece of rubber and make a gasket. Works great.
It's hard to put into print exactly how I did it. I'm not sure if I explained it well enough. If you have any questions, feel free to give me a call. Good luck.

Cut your rubber tank fill hose, install a sleeve from steel or aluminum, weld your fitting in with a slight downward (toward tank) angle. Hose clamp sleeve back in and your done. Eddie's idea is more professional but drilling the tank would make me a little nervous!

Nothing to it. We use a hole saw to drill the hole. Just drill it very slowly and have someone hold a vacuum. That catches all the shavings. The piece should stay in the hole saw when you punch through. You won't get more than a couple of small shavings in the tank, if that. It won't make any sparks so there is nothing to worry about. I have probably done 25 or more of them over the years and have never had a problem. Never blew up either

Yikes, I would seriously worry about the gas fumes entering the vacuum, the vacuum has plenty of sparks.

If you have access, you can also tee into the fuel fill hose? I think the fitting is readily available.
