cat d 315 fuel issue

these engine often need to be force fed the fuel to get it to bleed out and run. Try applying a light pressure to the tank and open up the bleed valves both on the pump and elsewhere.

its better to have a filter between the tank and transfer pump--will collect all the crud from the tank
systematically check fuel flow from tank.from transfer pump,from fuel filters,from injectors

tap ur fuel cap and use a valve stem with matching threads, pressure ur tank, like about 15-25 pounds, bleed system with compressed air is the trick i use. dans right, leave filter.

That's to high a pressure and will balloon your tank. 5-10 psi max is what I would recommend and even 10psi is high. (figuring all those square inches of tank surface)

I used my air compressor to help bleed the filters, Worked fantastic! Cracked the nuts feeding the injectors threw the compression release and the engine ran wide open! The throttle was about a quarter open. The shut off did not work, Released the line from the tank to the first filter and she ran out of fuel. Wow had no idea a d 315 could spin over so quickly, What do you think happened? Is the governor not working? I have a spare engine with another injection pump. This is powering my 1954 insley crane Thanks for the help

OOPS! Sorry! We should have mentioned that pressurizing and bleeding is done WITHOUT the engine running! :doh:
