I have been doing some research...
The A917C and the A1236C air filters are the same size in length and width. The difference is in the depth. The A136C is about 1/2" thicker.
If you want to stay with AC filters and want a 1 qt version (yea - DriVer I know .....
) then look for a PF1218.
Lastly the gas filter is "custom" made for WCC and nobody else uses it. The design remove the return fuel line from the engine according to I have learned. So, you will have to wait for the price to drop or make the converter to use the 03 style filter.
