Sounds like a good idea. I have the same regulator, but opted to put in a p=
iped bypass. Don't know if it works yet, but I don't see any reason it woul=
dn't. I press fit a rivet into an AN fitting and drilled a .020" hole throu=
gh the rivet, and piped it past the regulator.
Yours sounds like a much simpler and definitely lighter solution. Good thin=
king!
