It could be that in Al’s state, he can get Mogas without
ethanol. Tracy, however, in Florida, can only get it
without ethanol if he buys it from specific places. Distributers that
sell it, or boat docks that sell it. It is not available from a regular
gas station in Florida
as far as I know.

Well then, either you're very lucky, or VDO changed materials for their
sensors.

runs mo-gas which most likely contains ethanol?
Mark S.
I have run mogas more than 95% of the total hours.

SO, I can no longer recommend using the VDO
pressure sensors for use on fuel systems. Either an
isolator must be used or a sensor rated for fuel exposure be installed.
I've been using one on my -4 for >7 years with no problems. About 3
years ago VDO started putting a sticker in the pressure sensor package saying
not to use them on fuel pressure applications. I suspect they changed
something in the manufacturing process.
I’ve had my VDO pressure sensor in
service on the fuel system since first engine run in Jan, 2004. Still
doing fine. Must be they changed something after that.
