Hi , please unerstand electric or vacuum the princeables are the same ! just remember its all about flow ! think about it, all you have to do is get a schematic and isolate the circuts !! whats the differance between a
vac-pod or a solinoid ? a diode or checkvalve ? wire or a hose !!to me its the same! For the amount of time to convert I could rebuild a 617 !my 2 cents !
