120 hp vacuum??

[contractorguy]

I have a '90 Maxum w/the l-drive 120 hp. It was a basket case when I got it, and was missing a few parts...

It was missing the flame arrestors, and the originals are nla. I was able to get some for a newer ones ('92 I think).. The new ones are basically a cover w/ one hole for a vac line (I think), while all the diagrams I find (for the '90)show like three vac lines running to the underside???

Is there a check valve or something in there that I'm missing??

I have vacuum ports from the carb bases, and also the two bowl vent lines that need to go some where.

Any diagrams, pics, knowledge that might help me?? Thanks!

Steve,
Here's a diagram from dougrussell.com. You might be able to contact them to find the right ones or there's a place in Indiana called Indy Boats I think.
These covers look to be the same as the ones on my 1992 120 L Drive.

Thanks for the diagram MaxMan

I guess Im just wondering what's under there where the three vac ports on #18 are.

Also where does #24 and #22 go to? 22 to bowl vent?
