Evap port for M4M
« on: June 05, 2013, 06:03:47 PM »
Just got an M4M for a friend but it's missing the evap port. Looks like the tube is 3/8" but the hole in the main body is only .335. Does this make sense?

Anyone know how/where I can source something like this?

Thanks. Much appreciated. It's the one just under the front airhorn screw, points down and to the driver's side.

I'll double check my measurements but can't believe I was off .040 with a mic.

It's a 17080270 - for a 80 Firebird 301 W72 (non-turbo)
