Thank you.👍

Absolutely.I drained off the solution into one of those DEF fluid containers.I’ll save it and screen it for the next time since the solution still looks good.

The 3271 pencil injection pump is back together and ready to go back on the truck.I bench tested it with some fuel and cordless drill and it’s spraying fuel pretty nicely like it’s supposed to.Hoping tomorrow to have it installed.The ultrasonic cleaner did a great job of getting all the internal...

I used the vevor brand ultrasonic cleaner for the first time today and I was really impressed how well it cleaned up all the internal parts within the injection pump.The pump needed to be disassembled anyway to get rid of the flex ring and once I did,I found stuck pumping plungers.They are now...

Sorry it’s not in Missouri.He is located in Kansas.

That’s my plan as well.I have a few of these olds pencil pumps.Two have the EID updated cage but haven’t been used in a long time.I want to take them apart and freshen them up a little with a new seal kit after I put all the internal parts in a ultrasonic cleaner.Like you were saying as long as...

There is a guy on Facebook in Missouri who does a real good job on those pumps and injectors.A lot of people recommend him.Its Dennis Erickson.

It’s only found on olds 5.7 pencil injection pumps along with older John Deere and case roosamaster DB and DB2 pumps.The 6.2/6.5 just has a small pin that slides into the cam ring.This particular Bristol drive bolt threads into the cam ring on the olds pencil pump.The olds diesel with poppet...

Here are some pictures of all the parts on a table after taking the pump apart.Everything is pretty good except the Bristol drive bolt and advance piston due to the rust.The Bristol drive bolt is brittle and easy to break.I usually place a torx bit into the bolt with a couple small whacks of a...

Tonight the 3271 pump is apart.I found some rust on the metering valve area and down in the advance piston section.It had the flex ring as I suspected.It was on the verge of turning black and flaking away but the updated EID version will take care of that area. I plan to use my ultrasonic...

I have a ultrasonic cleaner here I bought from Amazon.Its the vevor brand.I plan to put it to use very soon.

I have a 3271 pencil injector pump I plan to put a EID inside along with a new spaco seal kit.Theres no “E” tag on the governor cover screw so it most likely still has the flex ring inside.The umbrella seals are leaking also on the driveshaft.I’ve used this pump I’m going to say at least 15yrs...

I had a few of my nos gm pencil injectors tested a couple weeks ago at a local stanadyne shop that I bought from eBay and the shop called to tell me they are junk.The pintle is seized with no way to fix them.Thats the thing with buying new old stock pencil injectors for this type of engine...

No problem.Glad I was able to help👍

Yes that is true.I believe I’ve seen this sort of thing with the 6.2/6.5 as well.

Here are a couple pictures I found online showing a hole in a 5.7 diesel piston because of a bad pencil injector.I’ve never seen this happen on the olds diesel.Very interesting to see that’s for sure.Supposedly the owner was saying the engine ran pretty good all along until this happened. It...

I’m heading back to work in a couple days so I’ll get back at the truck when I return home.I’ll put a clear hose on the pump return fitting and see if any air is upsetting delivery.I have a fuel pressure gauge here with a barb fitting on each side so I can easily make it a permanent thing under...

Yesterday I noticed a small amount of coolant under the radiator on one side.Has all new hoses and clamps on it.New petcock with sealer on the threads as well.It must have a small pinhole in it someplace.This morning I ordered a new all aluminum radiator on Amazon with good reviews so I went...

Here’s an updated video of how it runs now as of today.Much,much better at the moment.It runs smooth and then after awhile after reving it a few times and when it returns to idle it becomes rough again and not steady.Maybe an injection pump problem causing something to hang up or stick inside?I...

I have a new pop tester here I can try them on when the injectors arrive.I read the opening pressure on those pencil injectors is 1700psi and the later model poppet nozzle injectors is 1000-1225psi depending on the year. I have heard they are a throw away type of injector.Once the needle and...
