Hi all,
I did my searching and purchase a 75/76 air cleaner housing and oil filler housing with the bigger vacuum opening.
I have some questions about vacuum hose routing.
Per the pic attached and numbered my questions are as follows:
1. Circle #1 Oil filler opening to #2 on air cleaner (large 20mm openings)
a. Please confirm if this is correct.
b. Anyone know of a source to purchase these large diameter vacuum lines?
2, Circle #3 Two vacuum/vapor lines running from the frunk to the engine
compartment.
Question: Two lines and a single port left #4, how should I route these?
As always many thanks to the braintrust on the forum.
Thanks again
Click to view attachment#1 Yes, 20mm oil filter to 20mm air filter. dont know of any source for the original hose, you may need to go aftermarket silicone.
#2 Those are the lines that run to/from your charcoal canister on your gas tank. on the engine bay side one end connects to a port either on your fan housing or engine tin (depending on which fan housing and engine tin you have) and the other side goes to your air filter.
You may need to get a little creative with your house routing as the 75-76 cars had the charcoal canister in the engine bay so #3 in your picture didnt exist and the ports moved around a bit.
