hey there i have a D1105 kubota diesel that is not getting any fuel up to the injectors. the pull in hold in coil works. i put a new inline fuel pump on it. It pushes fuel up to the injection pump and the return lines on the injectors and back to tank. there is only 30 hours on the engine. and it has been sitting for about 4 years before i was able to get it. any help would be great.
