Hello, I'm having a fuel delivery problem with my 2003 T300. Runs fine from a supply line from a 5-gallon fill can to the primer bulb and up. When I connect back to the tank supply line (1/4" ID). It may run on low idle w/ no load. But when I try to do something with it, it will slow and cut out. Problem is I want to replace this line but access seems to be almost impossible. Is their any tips or tricks for me to look for. I've had the cab up but it appears the hydrostat is sitting over top of where I need to be? Thank you, Tom
