My ZenNoh ZL2000DT was recently run out of diesel. I've tried everything I know of to bleed the lines and reprime the pump. I simply cannot get the fuel flowing. I am afraid the problem may be with the injection pump. Is there anyone in the San Antonio, TX area that repairs or rebuilds block type inline injection pumps? I have found a couple of sources on the internet but they want an arm and a leg for their product.

Now I'm not positive but doesn't the smaller lift pump have a manual lever on the side to cycle it? Usually you can open the fuel filter bleeders and cycle the lift pump and then crack each injector line maybe 1/4 turn, cycle the starter for a few seconds and repeat until there is a drizzle of fuel at each injector, tighten the lines and it should start right up. use two wrenches on the lines for safety. If your tractor is gravity feed, then just opening the injector lines at the injector end should work. Best all around fuel injection pump rebuilder I've ever dealt with is Boston Fuel Injection in charlestown ma.
