would air in my fuel system cause this????

ok so a little info ive had a miss and injector cackle going on. i noticed tonight that when i went to start it i listened to the fuel pump and it kinda sounded like there was something like air going threw it. my question is if air is getting in there can it cause a miss? im still kinda new to diesels. if there is air getting in im assume its gettin in where the fuel line connects to the pump cause i replace the pump cause i though it was bad. i still have the oem one that i kept for a spare. the issue when i replaced it was the power wire was groundin out on a bracket that it had rubbed threw the wire. sorry for babling any info would be helpful. thanx

Yes poor fuel supply can cause a miss and poorly running engine. It is possible you are sucking air with the fuel pump.

Order the pre-pump/tank kit from diesel innovations and it possibly could eliminate your problem. I did mine and the truck is so much quieter it dont even sound the same.

Well im gonna try putting my original pump in and see what happens. the stuff in that kit i can buy at the local hardware store if i can figure out the sizes if compression fitting and fuel line they use for cheaper than they want for it. though i will keep that in mind if i can't figure out the sizes and the oem pump doesnt cure it.

found guzzles right up on the in tank prepump mod - Welcome to guzzle's In-tank Hutch Mod Web Page - so now i have the sizes and i actually have the compression fittings and metal line sitting here collecting dust. so if the oem pump doesnt stop the air im gonna do that mod.

well upon further inspetection cause my dad siad he smelled diesel when i was at his place, i found out that the water seporator valve is leaking fuel whick would mean air is getting in so i guess im replacing orings. i will be doing the tank mods when it warms up.

well it was the orings on the drain vavle. still has a miss and knock once in a while. im gonna do a buzz and contribution test as soon as my buddy gets back from bein otr. figured i update incase any one was havin an issue.
