What have you done to your CUCV today/lately - Part 2

[Finnegan1008]

Try adding some Power Service in the gray bottle. Don't be afraid to pour it in on the heavy side of recommended rate. Easy to see if it helps!

I’ve been adding opti-lube and I think it’s making a difference in my truck. Seems to start faster and idle smoother.

Realized it’s finally time to take off injection pump for a rebuild.

Not looking forward to this………

Getting started.

And you're halfway done

(Somebody's quote, but I can't recall who)

Getting started.

And you're halfway done

Been meaning to find out where/why the pump on the M1008 is leaking (other than because the vent line is plugged) for years.

How close to done am I? After all, they say that the first step is to admit that you have a problem. No idea who said that.

Pretty sure that it was NOT George Armstrong Custer. But that's all I got.

The hardest part about doing the injection pump is getting the intake manifold bolts out. They're the double ended ones and if the bolt breaks loose before the but does you have to figure out how to get a wrench under th fuel like bracket. I make sure to torque them during assembly and then a light snug on the nut.


Take your fuel lines off in pairs. Don't undo the brackets that between lines.

Update on my losing power issue.

Drove it yesterday and she starts right up and no issues whatsoever until you need to put your foot into it a bit.
Problem was worse. Not a lot but noticeable.
Exhausting every possible failure point before IP removal.

Is my fuel pump going out?
I cracked the bleed screw and cranked it (pink wire off) and no issues there. Great fuel flow

Used bore scope to check for water in fuel tank and condition of pickup sock.
Everything fine there……

I installed another new wix fuel filter.
Bingo!!

Truck runs normal now and plenty of power, well….., for a CUCV.
Clearly my almost new wix fuel filter that was installed a few months ago was bad.
Why? Didn’t have a clue.

Disassembled the “bad” filter and discovered the issue.
The paper filter element is held into place with some sort of really strong glue.
Some of this glue had somehow gotten out of place and blocked the fuel intake port just ever so slightly.
Don’t know why problem seemed worse, but just a different day’s perception

Random quality failure.
I didn’t take pics unfortunately

Best part!!
I don’t have to take my IP off just yet. !!

This is the first problem I’ve ever had with wix.
I will continue to use them and will probably never have an issue again.

Edit;
I am planning this fall having the pump rebuilt.
I have a complete set of NOS fuel injection lines in case one doesn’t cooperate during removal.

I think you should still change out the IP. This way you will know how to do it when the time comes.....

Glad to hear that you found the issue!

Absolutely agree.
Planning on it this fall.

 

[antennaclimber]

Let me know when you are changing it out, maybe Ill stop by with my lawn chair and supervise.

 

[Tinstar]

Since you’ve done at least 4, not a bad idea!!

Glad for you, Tinstar, that you solved that problem.

Life is good when a problem has a clear-cut resolution. Not always that easy. Good, though, when it is; you know?!
