[QUOTE="dano5535, post: 121300, member: 19025"] Hi guys, kinda new to this, but hopefully someone can help. I recently changed glow plugs and installed new fuel line, pickup tube/check valve and screen, squeeze bulb, and filter. Had a heck of a time getting all of the air out, and the fuel lines filled, then found the diaphragms in the lift pump punctured. Replaced them with some home made diaphrams I made myself with punches. Flow seems good. Also had to replace a o-ring on one of the injector pumps. Since then, the engine speed is erratic, and increases and decreases even when the throttle setting is fixed. Anyone got ideas as to how I can fix this or what is wrong? Thanks for any help, Dan [/QUOTE]
