I think my rear passenger side injector will not clear whatever box is sitting adjacent to the engine valve. If this is the heater box, how do you remove the vacuum reservoir? I didn't see any bolts fastening it, so tried to pry with a screwdriver. I got one corner up, but met alot of resistance and didnt want to break anything. I'll take a picture and link it if that will help. Going to get working on the other injectors for now, but will have to cross this road eventually to get that last injector out. Any help is appreciated.

Here's a couple of pictures of my engine above that #7 injector. The first is slightly zoomed out, you can see the #7 injector at the back:
and a bit closer up:
In this latter picture I drew a few arrows to point some aspects of this box. The red arrows show the only real seam on it - but no bolts to hold it down. The green arrow shows a moderately loose corner that I was able to get a screwdriver blade under - hoping it just popped out - but met more resistance than I thought was wise to force.
At this point I have swapped out injectors 1, 3, and 5 with rebuilt ones, but try as I might I couldn't get #7 past that box. Tried removing the top hold down bolt on the injector - but no luck there. Need a few more millimeters clearance, but it looks like removing that box will be essential.
So - any thoughts on how to get that out given that it doesn't have bolts?
The body of my truck is a 92 (with 97 engine, trans, differentials and suspension), so it might be a different part from the 92 vehicle.
Nope, it's the same. There's a little reservoir on the motor-side of the heater box that's about 5x10" and it has two screws in it. Just remove that reservoir and you'll clear.
Woah, nm my last post... It is different. The PBS trucks have a removable reservoir. Must be for that very reason. You're gonna have to figure out how to move that box over somehow.
Hmmm... If you go through the trouble to get box free and/or out, might wanna think about converting to the later housing so that you don't have this issue later on.
If I have to remove the heater box I may look into replacing that - if it turns out the reservoir is indeed difficult to remove. If its easy to remove, probably won't need to. I just was hoping someone who knew what they were doing might stroll by and give me a heads-up before I break something

Thanks in advance!
Ok, now I know that the reservoir of the 92 model its different.

I agree with that.

You know, if that glue acts as a seal (the reservoir does NOT have it's own back), I would almost say put a bead of RTV back down and attach it back with self-tapping screws. If the reservoir DOES have it's own back, then I'd just screw it back on with self-tapping screws. Then you'd be able to remove it later if you ever put injectors in it again.
Yeah, but I would think with that seam, you'd be OK... but I mean, even if it did leak a little, just a little bit of RTV on the screws would take care of it.
