My vote is yes. It will just dirty up a spot on your intake.

Looks legitimate. I'd be careful to not over pressurize it, use a bicycle pump maybe?

Put a pressure tester on it and let it sit. The leak will become apparent

The crickets are chirping... Did you make any further progress on figuring out the issue?

In your thread title you state you have a new injection pump. Is it new to you or was it rebuilt by a shop, tested on a bench and a known good pump? The fact that you are getting mist out of the injectors but cannot get diesel to drip with the injector lines cracked makes no sense whatsoever...

Is there a little metal tag with the letter E stamped on it under one of the three screws that holds your injection pump cover on? Metal "E" tag = newer style governor weight retainer. No tag = old style retainer that urethane ring falls apart and does fun things inside your pump. Tag is...

Any 73-87 2wd pickup, suburban or blazer. You don't actually need the entire box. All you need is the sector shaft. Most CUCV'S are low milage, and your box case is most likely in much better shape than whatever 200,000+ Mile junkyard special you may find. Just pull the pitman off of the...

Put the wire back on the injection pump. Pull your glow plugs and turn the engine over with the injector lines cracked loose until they are all dripping diesel. Tighten injection lines and turn over until you have a nice misty cloud of diesel puffing out of each glow plug hole. Install glow...

What size tires are you running? I have seen flat spots cause issues like this. Support your axle on jackstands with the tires just off the ground. You can turn the wheel by hand and gauge if it has a hump or flat spot. Some plywood and metal scraps can be stacked and placed under the tire so...

The nastiest paint remover you can get your hands on works well. I don't know what you can get locally, I have had decent luck with "Dad's" brand. Pull the heads, brush some paint remover on, sit, scrape repeat. I really don't like getting abrasives involved. A final good scrub with a rag...

That is way too high... unless it includes a new head and rotor...then it is still high. Unscrew the top, pour out the fuel. Double bag your pump and box it up. There are plenty of good shops to ship it to. I have had good and economical results with Redding fuel injection in Redding CA. I...

The 4524 is a HMMWV pump... I think. It will have a 24v solenoid that you will need to swap with a 12v. You might also find the HMMWV pump to be pretty aggressive. I think the total advance available in that pump is quite a bit more than the one you have. The 4544 should work nicely without...

If you want to clean up the wiring I am pretty sure the matching plug and pigtail for that glow plug controller is a ACDelco PT262

Both guys posted solid ideas. One thing, if you are not used to driving an older pickup with hydroboost brakes you will lose power steering under moderate to heavy braking while the engine rpm is low or at idle. The brakes get priority.

Honestly the best thing to start with the pump you have. Most CUCV's are low mileage, and that is good thing. There are a lot of different pumps out there, and the differences are the max fuel rate and advance curve. There is a steel piston that controls injection timing. It moves back and...

If you are heading north on I5 during your trip I know someone who has a starter in Yreka CA. It is about 300 miles north of Oakland

There are lots of options that a lot folks have done on the forum. Personally I have re-centered a couple sets of wheels. The stamped centers make the wheels about 3.5" offset. Flat centers set in as far as possible result in 5" ish backspacing. Stock HMMWV wheels are about 7" backspacing...

I am not positive about this, but I think with the steering wheel unlocked and with the vehicle supported with the wheels off you can actually manipulate the drag link and the arm that bolts to the top of the knuckle over the studs without taking any of the ball joints off. With 100% certainty I...

What are these Clark urethane springs you speak of? Personally I run around with the 5 coil Spicer kingpin springs and have not had any problems with plain Jane Spicer bushings. The old springs were 4 coil, and once they get a little weak they create problems. I know some people have posted...
