Vacuum line size

The 1.8 vacuum line diagaram here shows a 15mm line from the intake to the decel valve. Pelican doesn't have a 15mm line listed for sale, so do you use the 14mm for replacement?

I think that will work.

Yep it will work. I just did the vacuum hose changeover on my car (with Pelican sourced hoses of course).

I think the diagram is for a '74 though, and I noticed you have a '75 like me. You want to measure all hoses in your car that you plan to replace before you order. Although the sizes were right on the diagram, some of the lengths were different when I did it. No big deal though. Just had some extra.

Thanks, guys. After I looked at the entire page more carefully, I noticed that the sizes 13mm, 15mm, 19mm, and 22mm on the diagram became 12, 14, 18, and 21, respectively, in the table at the bottom.

Thanks again.

If you're planning to do them all, the largest sizes are not always stocked, you have to make do with heater hoses. I just clamped them and it worked just fine. Take a sample to your FLAPS and get the closest size. When it comes to hoses "tighter is better"

by looking at the diagram and specifically, at the decel valve, i thought the diagram was for a 75 1.8. my 74 1.8 is noticably different ie, style of the decel valve (similar to d-jet style) and charcoal canister is in front w/gas tank. no big deal.

Could be. All I know is that I ended up with a little too much of some hose, not enough of others. Maybe mine being a CA car is the difference. It's a great reference point though.
