Just An Op, I agree with you alot. There are flaws in all machines. Our rep in this area didnt mention anything about an upgrade steel plate over the fuel tank on the pt-100g. Sorry bout that. I subbed a contractor today to help me finish some work im behind on, he has a C-series CAT and i saw the non-repairable fuel tank in the rear. I noticed it when i told him his oil drain plate was missing. He commented " Its there for looks anyways!". Mine is a metal fuel tank, dont understand why they would put a plastic tank on a machine. As for the pump flow, after warranty ran out i sent it to a hydraulic specialist and asked him to do whatever he can to help with the flow and psi to be better productive. We even put in a radiator that has larger openings to let dirt an trash pass better. I've had it for 3 years now+/- and 1900 hrs. Its been good for me. SO FAR! Like the rest of us, im always trying to come up with a better idea to help.
