heres a dumb question(s) for you as I am very mechanically challenged… I have a 4gpm 4200psi honda gx390. The pump it came with is garbage and will soon crap out on me. However I know that the honda engine is pretty good so I would just like to upgrade the pump to an udor or some other high quality pump. My questions are:
-Does direct drive/belt driven have to do with the engine, pump, or both? If I have direct drive could I make it belt driven with a pump or is that all on the engine?
- My assumptions are that the GPM and PSI are dictated by the pump that I buy as long as it is compatible with my GX390 correct?
-Im also assuming that a GX390 would be able to handle a 5.5GPM pump but probably not a 8gpm ?
