I doubt the return bung has a pickup tube welded on it in the tank.

Bud, rip the old one off. Get the drill out and drill the rest of it out. If the old tube falls in the tank no big deal. Tap the remainder of the bung to the new size pickup and call it a day. It will drill like butter. It's aluminum...

Crawfoots suk..including no real leveage......nothing else will go on it ????

I'm assuming that little add a filter is for your fuel tank transfer pump to drain fuel ?

If that is actually how the boat is rigged, you may have better results if you get rid of it.

We have over 750+HP NA running -6 lines from the tank. At WOT at over 6500 RPM we hold a min of 6.0 to 6.5 FP (can't remember). My suggestion is to not change your fuel lines and put a FP gauge(s) either at the carb to test or permanently on the dash. If you have steady FP, this is all you need. If you want to confirm your AFR, put bungs in your exhaust tails to measure your AFR.

I have a 1/2" drive socket I notched to fit over the pick-up. Then you can hit it with a 1/2" impact gun.

those are good pumps.imo they will work well if used with the right regulators.

Okay, so I went back out there and slipped a 15/16ths socket over the pickup fitting and put my breaker bar on there and wrenched it out of there. Sure as hell, the aluminum threads galled up and stripped off the pickup. Now I am probably going to have to find a tap big enough to clean up the threads on the tank bung for the new pickup tube / fitting. Fok!



To make matters worse, the location of the original pickup is slightly under the floor up above it - to the point where there is not much of a way to get a tap in there and hold it straight. I would have to pull the back seat and the access panel over the fuel tank to give me a good shot at doing this. At this point I am real tempted to just use the other bung for my new pickup and crank my plug into the galled up original location with a liberal coating of gas resistant sealant. Not sure how comfortable I am with that scenario - don't want to be out in 4 footers with a full tank to have that fitting start leaking on me.

Can I have something go right on this damned boat?

Anyone have an idea where I would locate a tap to fix the threads on that bung? Probably a 3/8" or 1/2" pipe thread from the look of it.

Anywhere that sells machine supplies. MSC, McMaster, travers

Did a quick search and it looks like the taps are available many places. Going to try some of my friends to see if they have one laying around - probably a common item on a plumber's truck. Also, HorribleFreight looks like they have a cheap set, which would probably work fine cutting through a soft metal like aluminum. Stay tuned.
