We have aux electric pumps on both the Royale (JimK design) and the Clasco (JimB design) and have not needed either since adding ethanol conditioner to our fuel. We only buy regular fuel from Costco, Chevron or Shell. No odd ball brands and have done so from coast to coast without issue. Mileage suffers in the Midwest but even in the extreme heat of TX, NM and AZ no vapor lock.

Recirc systems can get to be a bit of a project. I believe necessary sooner or later. However for quick, cheap and reasonalby effective system Jim
Bounds trick of installing a booster fuel pump between the aux tank and the selector valve can't be beat. The pump is powered from the selector valve
terminal. If you start getting vapor lock switch to the aux tank. The booster pump will pressurize the system to, hopefully, block the vaporization.
