Your video saved me, I was discouraged and never would of realized the 2 pumping plungers existed and how it works, mine must have been seized up so I ressurected it.

Warren, the hand sure take a beating in the mechanics trade, just part of the job. This will kick the old guys ass later in life. Hands of a working man. Thanks for the video on this pump.

Thanks for the video, i just went through the pump one my john deere combine saved a bunch of money.

Thank you for all your videos. I was a marine repairman and I changed jobs. I had been missing the great dealing of solving trouble with machines. I found your vedios and have been able to enjoy the great since of repairing the machine and staying clean at the same time. You do outstanding work. I wish you all the best. Jesse

I love the history you add to your videos.

Very interesting to see the inside of a pump. Good for you I guess to have a break from the heavier stuff !

Thank you so much for making this video! I broke off the throttle lever on my 1976 Case 480c construction king and was faced with buying a new injection pump or fix the one I had. Found out that I could replace the rod and wanted to see what to expect. This video is awesome!! Thanks again brother!

I'm working on a Stanadyne DB4327 right now. This video helped me out quite a bit Thanks!

Nailed it again guy, super job for us trying to learn. Thumbs up BIG TIME Warren.

thanks to your two educational videos I rebulit my 6 cly JD induction pump Roosamaster. Updated weight cage new bushing new vane pump assembly ect ect. Installed it and with the help of a gasoline soaked rag started right up runs just perfect.

Thank you Warren. Had my first run in with one 9of these today. Leaking from that bottom flat head plug.

Hello Sir. I understand how busy you guys stay. I have a Massey Ferguson 50A backhoe I hoped I had gotten a good deal on.and I wish the pump had been that clean. Mine was full of Sludge under the top cap. It's a DAV type. Had water half way up the lower part. The rest had went inside the motor. Because I believed what the seller told me I tried to start it. I think it messed up all the injectors has it pumped just enough to move the dirt/dried fuel . To say the least parts are putting a hurting on my wallet. : ) May has well laugh about it.

Thank you for making this video as well as all the other ones. Every time we had one of these pumps give us a problem, it cost us between $500-700. Just took one apart today and resealed thanks in part to your video! Total cost: $37
