Mine went out the first week that I got my vette. I knew nothing about what I needed to do at the time and had no knowledge of the forum for help, so I let a dealership do it. Hope no one else makes that $650 mistake.

Practice makes perfect! I think I did the last one in 2.5 hours.

Fuel injectors are way more fun.

Yep you got into the prize area of R&R.

Wouldn't you just love to have that design engineer over for tea...or something like that.

Funny you should mention that. The first time I did injectors, it took me, oh, 7 hours to do. I broke parts. I cursed. I started around 10PM, and by 2AM was at the point of violence so I turned in for the night. Came back the next day and buttoned it up. Sneaking those runners back in is the hard part, if you ask me.

On the other hand, I just went out tonight and pulled the plenum/runners to send them out. It took me 25 minutes to get everything off. I think I could do injectors in about 1.5-2 hours now.

I think I'd just give him a friendly kick to the sack.

When the engineer made the decision to route all those lines through the brace he must have been drunk.

Do you have the cold start injector? That makes it even more fun. With the allen bolt kit and some special tools, i don't fret it anymore though. I need to program out that 9th injector.

To get to the water pump i believe only the fuel lines had to be disconnected to slide the a/c bracket off the left w/p bolts.

First major repair to mine and I discovered again what I learned in the Navy. I still have a very good four letter vocabulary. If I had the engineer over I would tie him to a chair and make him watch one of the religious channels for about 48 hours stright.

Hi Tony, how have you been?

When I was removing the A/C / tensioner brace, I made an executive decision with the help of my friend the sawzall. I removed the part of the brace that runs under the fuel lines, so I didn't have to disconnect them. While I was studying the design of the brace, I saw no benefit to having that section of the brace. I did have to disconnect the heater hose and thread it out of the brace before I could remove the brace from the studs on the pump. Once I got it off, I put a notch in the backside, so I can just slide it over the heater hose now and zip tie it to the brace to keep it from moving. Next time will be MUCH easier to RR the pump.

I do, yeah. Maybe you can shed some light on this, as I'm going to have to pull the runners on monday - do you have a good way to get to that rear, drivers side bolt? that must've taken me a good 30 minutes with varios extensions and u-joints....

Nope. Not at this time. I still need to get this part looked at. I should put the broken part in from of the computer...

The two pictures above show how I modified the A/C / idler bracket so I didn't have to disconnect the fuel lines or heater hose.




I painted the air pump flat black, can't even tell it's there anymore.



The leaky problem. The inside of the pump looked good, but the front seal and bearing was shot.
