[alfa] Re: Bosch FI hose replacement, 7.5mm v. 5/16"

["Dean W. Cains" <dwc@xxxxxx>]

Hi Jason, and Group:

Here's a pointer to a site that shows the "correct" injection hose 
replacement procedure.  I can't criticize anyone's method's, as I haven't 
yet done the job on what is my first non-Spica Alfa, but this method seems 
very sensible and directly addresses the issue of 7.5mm versus 5/16" hose, 
at least for the L-Jet cars.  Someone else will have to confirm what's 
right for the Motronic's.

I've already got all the parts, though, and I bought the 7.5mm hose from 
the local BMW dealer.  I snagged the URL from a previous posting to the 
Digest, but can't recall the original poster.

Regards,

Dean
