question to those with Alpine SC

[WormGod]

Reiterating a question from my last post concerning the fuel pressure regulator, but with pictures this time to try to get my point made more clear. Basically, there is a protection bracket (so the workshop manual calls it) surrounding the regulator that houses a wire harness connection and 2 small ports.



(2 and 3 below point to the 2 ports on the protection bracket w/ wire harness port)



Besides getting the right length hosing to finish the install and figuring out where this bracket and these ports fit into the S/C equation, these are really the only things holding me back from finishing. Any out there that installed their own S/Cs got the answer I am looking for?

S/C installs were clearly more simplified on PRE fuel injected cars.

IIRC, & it's been a while...I removed the bracket from the vac. controlled mechanism & put a piece of vac. hose between #2 & 3 in pic 7. Then just zip tie it out of the way.
I think those lines had something to do with the small cannister over by the cruise control/ ABS module which is abandoned also.(not the ABS, but the small cannister) I put a piece of vac hose between the two ports on the cannister to keep things clean in case I ever want to go back to the NA setup.(not likely )

I have a diagram of the vac hose routing if you need it.

Gotta love the incredibly vague install instructions from Alpine.

Oh dear god that diagram would be extremely appreciated!! I understand the majority of the hvac hosing, but the smaller lines have me a little confused. Especially things like that which you mentioned that were "left out" so to speak. That diagram would rock Ldub. I hope to document ALL of this information from my build into the S/C install thread that I started for any future S/C installers or repairers so they dont have to ask as many questions as I am. God knows, if you do a search on here about S/C issues, it turns up more threads than eadlight gaskets and power window issues, haha.

Thanks Ldud!

I'm not sure if this will be of any use, it's a little more vague than I remembered (big surprise, It's from Alpine ), but it helped me get it right.

Actually, that is GREAT. On the bright side, that is exactly how I figured the fuel reg was supposed to go, but it's a good reassurance. Odd that there is no S/C "plan" for an alternative for the sensor on the protection bracket, but, like you said, that's Alpine for ya. Thank you very much. Just need to aquire my vacuum hose now. Hopefully this weekend.

I hope you won't mind if I use that pic in the ref guide I am compiling? It will be a good help for anyone in the future.

Be glad to help, I got it from Tone & assume that he got it from Alpine.

Dub,

Do you know whether you still have the reference hoses to these numbers? Would be so helpful if you did (example: fuel regulator vacuum to number 1 etc). Thanks

It'll take a bit of digging, but I'll see what I can come up with...

Well, I looked at the various shop manuals until I was almost cross eyed, THEN it dawned on me that there is a vacuum hose routing diagram...under the hood.

Smart @$$ directions...

Open hood -> look up ^......

With a bit of head scratching, that should pretty much tell you where everything goes...

That's if you aren't on your 3rd factory hood... like me. Nil a sticker on the hood. *sigh*

I don't envy this task. I was NEVER any good any remembering/memorizing vacuum plumbing. Though, if you know what all the connections are, reverse engineering them is actually not too bad on the VX. Looks like a lot of lines, but it's really not too bad. I have actually "considered" just taking out the S/C and selling to go back to stock it but I think that would lead me to selling the VX. To be honest with ya, the thought continues to haunt me and I do consider it....

Looks like I'd better spiff er up a little & take a few pics for the archives.

Dub,

Thanks for all your efforts! I learned that my SC may breath yet again. All the damn noise I've been hearing is due to a loose 5 lb pulley and a bad bearing in the tensioner pulley. There is always a chance that the shaft may be bent as well but he (mechanic) didn't think so but won't know for sure until he gets the parts. Which introduces the bad news. Alpine is gone but there are places out there that service Eaton SC. So the hunt begins, and if I can find the parts I may be back in business. If I can't find the parts or the shaft is found to be bent, then I'm back to installing the OEM system. Thanks to everyone for assisting me.

FWIW...the NSK part # for the S/C tensioner pulley bearing is:

6301C3 OR 630IC3...depending on wether my illegible writing meant 1 or I...

OK...just found out for sure, it is a 1...http://vehicross.info/forums/showpos...77&postcount=2
