Bleeding the injection system and do not get any fuel to the injectors. Hand pump pushes fuel out all the bleeding taps, but nothing out the lines. We have spun it over with the starter and still no fuel. Is their anything else to do before taking it to the repair shop? Thanks in advance. Jo [Reply]   [No Email]

Almost 1/8 NF pipe but I am not certain. Pump shop kept my fitting and I am having trouble finding the fitting. [Reply]  [No Email]

We have a older cummins with the old style pump and it was running rough , removed the injector pump sent it to shop, complete rebuild now it just like yours, fuel thru all the bleeds and lines but no injection pressure .

Spent another 4 hr's on checking every thing out and finally pulled it off. The shaft is turning and every thing seems okay. It's got me stumped so it's off to the repair shop on Monday .
