Reply to lil cat mec:
im not sure about the brass nuts, mine was replaced with steel if brass came factory, last month i made my own gastket and replaced with grade 8 washers, studs and nuts!
I have not painted mine yet so im subscribing for what others say for the manifold!
yes the on/ off switch should go to the mag...
there is a sticky at the top of the discussion thread with parts, Then and now 1-781-335-8860 .you must have the stamped # on the fuel pump before thay will sell you the kit.
i do not have a muffler on my 22 just a set of radio earmuffs lol
good luck with the POR15... im thinking about using it!
I suggest you get your new studs and manifold gaskets from Florin Tractor Parts, I bought some manifold studs from my Cat dealer for my 15 and they were $112 for 10 of them, ouch, and they flew them in from Singapore, so I had a freight bill too!! I just bought new manifold gaskets from Florin, about $6 each, and new exhaust outlet stub ($40 I think it was), they have the studs, but not the brass nuts, nor does Cat. I'm 99% certain because I asked a month ago here in Australia. Use high temp thread lube on the studs in case you need to remove those steel nuts at a later date.
I use the high temp exhaust manifold paint in the spray cans, it works well and no need to bake, costs about $16, Cat. have their own cans available. I just bought new fuel pump diaphrams for my 22 from John Matta down in L.A, you need to cut the holes, but at $5 each you can't complain, he has the small gasket for the glass bowl too.
Good luck
Mike
