We got newbies and ladies and variousfeller-type folks who really can't understand why the stock vac actuated petcock can be the root cause of so so so many of the different issues that they bring to us.

We have put together a visual aid so you can see graphically and metaphorically the exact issues that take place when you give your vac petcock equipped engine the gun in traffic (expecting it to perform) and it begins to sputter & choke and die on you in traffic.

You don't need the words, just look at the faces as the operator gives it the gun in traffic and the vac petcock fuel starves the engine until it dies leaving the poor operator aghast and completely stupefied (and stranded, of course).

The last little bit, when the engine is on its last gasp is when the diaphragm splits down the middle and drowns the engine (and the oil in the sump) with copious amounts of raw gasoline .....  


(watch his eyes roll back and his tongue hang out,   exactly perfect !!)
