Well my kit finally died. Funny thing, the pump is still going, even though it has Viton valves. I imagine they will show some wear when I tear the pump down.
The check valves went first, they were Viton. Seal is gone, and they leak. I drained lots of methanol into the bottom of the intercooler, and gulped it up a couple of times when I cracked the throttle.
Good news is Buna-N is supposed to be rated A with methanol, and I can quickly replace the check valves with Buna-N ones, and the valve on the pump can be changed with either Buna-N or EPDM (also rated A with meth).
This website sure hit it:

With methanol
Teflon: A
EPDM: A
Buna-N: A
Neoprene: A
Santoprene: A
Viton: D
BTW, ethanol and isoproply rate as a A with Viton.
That could be it, the weakness. Get rid of the Viton in whatever combo you may have and it shouldn't make a difference between denatured and methanol. Viton is pretty common, so most things you may put together will have some Viton unless you try and avoid it.
I had Teflon lines, Neoprene feed hose, and Viton check valves. The Teflon and Neoprene look uneffected, the Viton is screwed.
Oh and you can/should use sintered bronze filters. No sign of any corrosion on mine. Don't use paper, heard first hand meth will eat it to mush and clog.
