New Holland TC30 fuel problems

[wintergreen67]

Brief description on how it started....
Was using box blade dragging dirt when i started loosing power. My first thought fuel filter! Made it back to the barn and changed out the filter. I bled the pump with the bleed of bolt on top of the pump. Thought it was OK so i went back to dragging dirt. Started loosing power again so i stopped and bled all the ejector lines at the motor. got it going again and it lost power after 15 min. I'm i missing something?

Welcome to TBN...
How many hours since your last air filter change. Maybe that's dirty as well. Seems like you got the air bled out of the fuel lines.

Thanks
I cleaned the air filter when i changed the fuel filter. Did that for cheap security, just in case it was the air filter too. The fuel bowl had a lot of sediment in the bottom. The only thing i havent done yet is blow out the line going back from the pump toward the bowl. Thanks for the tip....

Sounds like it might be a clogged pickup tube in the fuel tank or debris clogging the bowl inlet. Maybe you can blow backward toward the tank. You could also loosen the filler cap to make sure you are not pulling a vacuum on the tank. I made the mistake of adding gas to my 29DA and it would lose power when warm and working, but start and idle OK.

That's what has happened to my Sc2400. Some times it will run for hours without problems and some times every 15 minutes it will loose power stutter and then shutoff. I then get under the tractor unhook the fuel line coming from the tank and stick a piece of wire in the nipple. Hook the fuel line back up and it will run fine for a few more hours. One day I had to do this 4 times in 30 minutes before it would run the rest of the day without problems. When I changed the filter there was black sludge that I assume is sitting on the bottom of my tank that some how I need to get out.

I had thought about taking the tank off and cleaning it but after seeing that I'll have to disassemble the drive shaft, I'm thinking about using some type of suction pump/vacuum to see if I can get whatever is in the tank out. I tend to notice that the fuel tank is about half full when I start having this problem if I do have problems.
