Installing + tuning Injectors, Delivery Valves, and Governor Springs in a 12v Cummins: Part 2 

Glad to be a bad influence in your potential next purchase 🤣 start looking, they aren’t getting any cheaper!

I'll get on a pump timing video, I have a hillbilly way of doing it where you dont need any special tools and it can be done in minutes!

Glad it was helpful! Thanks for the comment :)

Good idea! Maybe I got a faulty one, I’ll see if I can get in contact with a snap on dealer

Thanks!

I’ll have to give that a try! Sometimes there’s a little dot in the centre of the tamper proof screw, I imagine that’s what you’re hammering into

@Hazardous-Hotrod-Knowledge Yes, it has a small indent on the top so when I tap the torx in, it is able to make its own shape, plus I think the shock helps loosen the bite before trying to turn it. I believe it is a 25 or 27 on the top and 20 on the smaller afc housing back plate. I reuse the same fastener once doing this.

One guy suggested to get it warrantied, so I’ll try that and if it’s still junk I’ll pick up one of theirs!

@@Hazardous-Hotrod-Knowledge yeah they're awesome specially made for delivery valves

Ive used “handytek” Amazon 4k gov springs in more applications than I can count and have never had a single issue. What trouble have you been having?

I used a set of DAP springs in one truck and they were super touchy. Almoat felt like 5k springs. I've adjusted them multiple times and still can't get them how I want them. The other 2 trucks I've done I've used cheap ones with decent luck.

It’s more than that for the differences between the pumps. The 180 and 215 Hp injection pumps have a completely different pump cam that delivers fuel at a faster rate, as well as having a better plunger design. The copper washer is just a different sort of thing they did with the barrels in the 160/175 pumps to seal the delivery valves and was done away with the later pumps

@Hazardous-Hotrod-Knowledge Thanks for the reply I did some research and found out the same , I am bummed because my engine was built as a high output with a 215 pump, but a shop replaced the pump with 175 horse yrs ago .

I set up the AFC housing pretty mild but typically a truck with these mods on the stock turbo will go to about 350hp

No estoy seguro de cómo traducir al español y puede ser mucho trabajo con todos los subtextos que tengo en el video también. Gracias por ver y estar interesado en el video, espero que de alguna manera puedas disfrutarlo :) Utilicé un traductor en línea para esto, solo puedo hablar inglés.
