Plastic tube bolted to front of block

[Naj ✝︎]

Been following this thread for a while and I finally went out to look at my car to see if I have the mysterious plastic tube. Nope. My car was built in July '68 and sold as a '69 so this must have been a later addition to the California SL's.

Hi, John,

Your car should have the 'FSVT' (funnel shaped vent thingy) under the right rear bumper between tank and exhaust box.

Hello Naj,
 You are correct, I have one of those little "FSVT's" hanging down next to the exhaust. Looks a little grungy in this photo:-(

John, I see that another project has just surfaced.

More evidence no two MBs were built alike. ..

Looked at my 280SE four door- and there was the barbed right angle fitting coming out of the dizzy/FIP drive cover plate bolt.   It has the later head with the temp sensor back at the #6 plug.

Thanks very much for all the comments on this question.  If you have been following my post on the 062 distributor, you will see that the mystery has been solved.  Apparently this 68 of mine has a 70/71 engine.  That explains the vent on the front of the block.   Earlier engines do not have this vent.   Any harm done in leaving this tube open as it is now I would think some type of screen or filter may be in order, to keep anything unwanted going back down that tube. 

Your input is appreciated.

If you don't connect the tank vent to the block(barbed tube), I'd seal both ends- the barbed tube and the plastic tube to the tank.  If the barbed nozzle isn't sealed, outside air (and dirt) will be sucked into the block.

Thank You Glenn, I'll get to work and get this done.  I'm thinking a cap on the tube might be the ticket.
