I can't givevan opinion on your water pumps.
I don't know what's available or how they hold up.
I always tried sticking with new ACDELCO
I stay away from Rockauto. No customer service if you have any issue with the water pump - that's my experience, anyway.
Rockauto was all good until...
I'm not up to doing anything right now. Maybe in a few months.
Just got back.to bed from trying to bait some traps. I've got a long list before messing with the dash would get to the top.
I don't have much luck finding anybody hire for anything simple. Much less something like that.
I've never had much luck reviving an auto trans with a fluid change.
Even though I always changed my trans fluid and filters, I still never made it over 300,000 on an automatic transmission.
I'd just change the filter and see what it does.
I know there's Triangle Diesel in Irwin Illinois and the place in Michigan I used to use.
I don't know that either are still doing 6.5 Diesel injection pumps.
I sold the 1996 with rebuilt injectors and injection pump for less than the IP was worth.
I know Triangle Diesel was still...
Are there any places that would rebuild either of your injection pumps that you could overnight it to And get it back in decent time?
Could your air infiltration be after the fuel supply hose to the IP - at the nipple or the fuel pressure gauge T area?
Is there any area you can isolate and put air pressure to?
I've added ball valves and pressure gauges to things and then pumped them up.
How much pressure can the fuel system stand between the tank and the IP?
I think I might be suspect of your IP or FFM. Possibly fuel pressure gauge sending...
Been there. The water can't be lower than 25' or it won't suck.
I wish I hadn't plugged my old well. At one time, I was dug down deep enough, I could have put a pit in.
I'm guessing they lied to you.
I seriously doubt autozone would sell tested and balanced injectors
You need to take them to a good rebuilder or contact rockabilly here
