There are two fuel pumps for 455.
One has a metered vent line, these are not the part for our coaches.
The other has no vent provision.

Because of fate's intervention, I now have a coach with the wrong pump. (I am thinking this is temporary.)

To combat vapor lock, has anyone ever taken that vent fitting and piped over to the fill vent line(s) that are in the left rear of the engine space?

There were a plethora of such things done in the mid-70s when engine space temperatures went up. They were known to have varying degrees of success.
