I recently bought my first steer loader. After several hours of operating, I noticed fuel leaking from gasket on top of injector pump. I ordered the gasket and replaced it. But when I took off the cover all fuel from injectors lines emptied. Now I can get fuel up to the pump, but cannot get it back up to the injectors. Can anyone give me a suggestion?

I assume a perkins or isuzu engine?
There should be a hand primer in there somewhere, give it a good squeeze. If you crack the injector lines and spin it over, you should get fuel to the injectors. Tighten them and you should be good to go.
I have never worked on one of those engines, but the priming is pretty well the same on all diesels.

It is an Isuzu-4JB1 engine. I've tried that, I even have the front 2 injector lines off. But I pump it up and bleed the pump then turn it over, no fuel. Its like the fuel is shut off inside the pump. Thanks for any other suggestions.I assume a perkins or isuzu engine?

You mention it's acting like the fuel is off, could the fuel shut off be the cause? Do you get fuel coming out just before the injector pump if you squeezt the primer bulb?It is an Isuzu-4JB1 engine.

Just want to make sure you are getting fuel all the way to the pump.
Yes. I have even removed the bolt at the end of the plunger barrel and I get fuel there, but it still dont deliver out the injector line fittings.You mention it's acting like the fuel is off, could the fuel shut off be the cause?

Yes. I have even removed the bolt at the end of the plunger barrel and I get fuel there, but it still dont deliver out the injector line fittings. Also today I removed all injector lines and pulled the delivery valves. They had some grit in them. I can hear the fuel shut off valve open when the switch is turned on. I am running out of options, and I don't want to remove the injector pump because I know nothing about the timing of it.You mention it's acting like the fuel is off, could the fuel shut off be the cause?

You have gotten in about as deep as my knowledge goes, hopefully another member can give you some advise to sort it out.Yes.

Is the fuel shut off staying open while turning it over. I have had various machines that would drop the shut off while cranking it. If possible hold it or tie it so it cant shut offsomeone, Everyone, I STILL NEED HELP!!!!!!
