Just Orange Bosch 19's, I'd get the updated ones. 4 hole I believe. Nah they don't need to be new...rebuilds or remans. Same as new, all wearable parts are replaced. As dirty and caked up as that engine is, I bet you notice a nice boost in performance. I changed mine out at 160,000 and it felt like a new truck again. Went from a slug to having a little pep lol.

How about these?

 

Those will work for you.

The set you receive might not be as polished up as the injectors shown in the pics but will be rebuilt and function like new.

I swapped mine for an ebay set @170K and definitely felt an increase in throttle response.

 

FYI - Those are not the 4 hole design, which atomize the fuel.... and they are the injectors JBrew speaks of. Those have a single hole pintle cap.

 

Now I'm confused. The description says 4 hole, but they aren't? Sorry don't know anything about fuel injectors. Will start googling!


Update: The seller is great at replying and provided this picture. Good?

 

Yes those are the best you can do. Fat 19lb 4 holes. Those are the truck injectors. There's 2 body styles short fat and tall skinny types. The injectors you posted are the best for the original power plants in these trucks. The truck engines upgrades.

Whitegt was most likley confused because of the hats (brown jet caps)...or thought the design 3's were the upgrades (tall skinny type 19's they used in car lines).

 

My bad... those are indeed are 4 hole. I was not aware that there was ever an EV1 injector with a 4 hole tip. I thought they were all pintle (one hole). I thought the EV6's were the first style with 4 holes.

I apologize for being misleading.

EDIT: Stole this pic from the web for a comparison.... the left is pintle, the right is 4 hole (aka DPMO - direct plate multi-orifice)

 

Yea, these came later. They look like the original single hole, until you see the pintle.

I'm using the other, these are 5 hole, -



But, they aren't as good as fat 4 hole.

 

Now I gotta figure out what came with those injectors. I have six brand new 19 lb EV1's in a box somewhere (I just moved, so good luck to me finding them). Never taken the red protector cap off of them, so I don't know what those are. I have 30 used EV1's that are all single for sure.

 

EV1's were gen 10's originally. EV6 were car lines. Just to be clear, the difference between the two (1 and 6) is just connector type. Not injector type.
