I installed and electric lift pump on the bobcat a year ago.... it ran fantastic...i never thought of checking the clamps to make sure they were still tight. Perhaps I have air going in from the clamps. I will keep you guys posted. Thanks for all your help
With it bogging down when useing the hydro and getting better when you let off I think your main problem is your hydro filter(s) and your ajustment for your steering

I have the big brother of yours a 743 so im pretty sure we are close one thing that is missed is greaseing the ujoints from the engine to the hydro pump there are three zerks if they break it will cost you dearly you can replace them for about a hundred bucks and a half a days work
