Ok i HAVE the vacuum line that has the 2 little diaphrams.. im missing the one vacuum line that goes from the intake elbow to the opti.. i really dont want to spend $70 on ebay for those lines..

anyone make their own? Anyone know what size that little blue 90* hard plastic fitting is than goes into the elbow?

bring the blue fitting with you to an auto parts store and get matching hose, thats the easiest way if you have the fitting that is

I need to make a set from scratch, anyone have an idea where you can find those check valves/filters,...what ARE those, anyone know?

IIRC there isn't a valve, filter, or diaphragm in that line. Just got to a parts store buy an assorted set of fitting for a pew bucks and I think its like 1/16 or 1/4 id tubing.

just replace the hose as stated or if you want the whole thing..

I bought 2 back in 2009..they were around $35 with shipping then.

vacuum harness I think was the term..
this is the part number from shoe box's online stuff..that's the best resource I've ever found..

I've never found the blue diffusers anywhere seperately..but someone
may know..
their purpose is to slow down the air so it's not a direct vacuum leak..

yeah i have those check vavles.. and that particular vacuum line.. the line i need is the one with the 90* blue fitting that goes into the intake elbow.. it just looks like a 5/32 vacuum line with the blue fitting..
