Gentlemen, I got the E8135 installed for the primary pump, It installed well in the factory position. The top line is a bit of a stretch, but I got it to reach and hooked up. Runs like a champ again. Next weekend I'm going to replace the Aux pump as it has failed too. I'm going to Light In The Dark's post as a reference. I'm actually hunting a second generator for my neighbor. He likes my set-up and wants to duplicate it at his place. I'm going to check the classifieds now. If anyone has an alternate source for an MEP 803 it would be much appreciated. Thanks again fellas!
