Re: [FlyRotary] Re: Vapor Lock
Hi Paul;
    I'd suggest that now that you have the vent tube, you really aren't concerned whether the Facet pump will allow backflow. As a matter of fact I 'd even suggest that I wouldn't want it, but I'd certainly want the ability to pump it forward to force cool fuel into the header tank, thereby forcing any possible vapour back through the vent line. I don't have any problems drawing fuel through my Facet pumps and I wouldn't be without them.
 
Just my 2 bits

Thanks for the info, Tracy.  My only concern is this....if the Facet pump was not involved, might it be better to have it back in the system so that if I have a future problem, I could turn the Facet pump on to pressurize the sump tank with fresh fuel?  Ed seems to be comfortable with this, and has had to use it.
