question to those with Alpine SC

[ScottinMA]

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.

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

Dub you are the man! I've been calling everywhere trying to get these parts. Is the Alpine SC (I have one of earliest versions) a Eaton M62? Now if I could just find a SC pulley...
