Some More engine questions on my 94

Ok, so i dont know if you know, but i own a 1994 Chevy ZR2 S-10. With the vin "W" motor, and the 4.3L engine, now i have a spider injector setup. My questions are as follows:

1. When you turn the key off is the fuel system supposed to hold pressure or drain off?

2. Does the fuel regulator valve supposed to change between idle and throttling?

3. Should the fuel pressure change between idle and throttling?

4. Does anyone have a really good diagram of the spider injector setup? and or the vacuum hoses and system?

Any answers would be great. Thanks.

1. I'm not sure what year they went to draining off, but if yours does drop, it should be almost instantly at 0, or no drop at all (a few PSI would be ok).

2&3. Fuel pressure should rise with throttle. It should almost double if you snap it to WOT.

4. I'd buy a repair manual for your truck. Should have a diagram.

So I go to this get-together at a friends house, not remembering it's a few days before Halloween. I see a bunch of dirty looking strangers. Then I see a guy that was clearly wearing a Halloween costume and I make the connection, and say "Oh yeah, Halloween... y'all goin' as a group of bums?". Turns out they weren't wearing costumes.
