anti siphon valve removal

[gaptaker2000]

I just bought a 2004 sea pro bay boat. The siphon valve coming out of the gas tank broke . This appears to be an aluminum fitting. Any tricks on getting the fittings out. they seem to be seize together. I have used a can of liquid wrench, this has not loosed it up. The location is not the easiest to get to and I am afraid I will crack the plastic gas tank.
any ideas?

try PB blaster.

I had to use a pipe wrench, but mine was metal to metal. When you replace it, put pipe dope on the threads but use the blue tube, not the silicon tape, which will melt from the gas. And while you want a good seal to keep water out, it doesn't have to be air tight to function, so don't over-tighten.

I appreciate the thoughts... what is BP blaster? will it work on aluminum? this is driving me crazy. any thoughts about just attaching the hose to the part that is still sticking out?

PB Blaster is about the best "loosener" out there, most auto parts, industrial supply stock it even Home Depot. A little heat on the outer fitting only, back up with pliers, vice grips or something to help from cracking your plastic tank. If not you may have to remove the bung from your tank and do it on the bench.
