Bad luck with Q1250001 filter assemblies.

It seems i get only a few primes each unit. Is there a rebuild kit like they have for duramax's? Anywho got an assembly on the way. The original lasted a long time and several uses. The replacement, an exact match I got one maybe two primes and its been at most 2 years. Now I've ordered the LS x-ref- It has a hex head instead of thumb screw air bleed. Everything else is located the same. I'll be taking apart the one i remove and maybe concocting a way to circumvent the silliness and plumb in a primer somehow. very frustrating to be down for days waiting on a part. I tried the blow compressed air across the bleed hole trick. I've had that work before. Not this time. If the new one works, I'll buy a backup. Would be nice to have rebuild kit.

4340c ... stopped like you shut the key off...

The 4340c just shut down like you shut the key off ... had the hay cutter on it and the grandson was cutting ... she just quit. I topped off the fuel, primed the pump on the filter ... it fired and ran about 10 seconds and died ... so I'm thinking fuel filter is bad. Today I replaced the fuel...

got it running. the above thread has lots of good info. i pressurized the tank and got fuel out the bleed screw. then the last post in above link helped me understand bleeding the injector pump. there is a fitting with a bleed nipple. i did both procedures a few times and finally got the air out. and it started up.

now primer works.
