Yup. Covered that with when i said NPSHR.Big Tea wrote: ↑28 Mar 2022, 22:53But if the E10 was more volatile would it not be more prone to 'producing' vapor locks?PlatinumZealot wrote: ↑28 Mar 2022, 18:12It wasn't E10 degrading anything. They confirmed its low suction pressure. Very likely way below NPSHR required for the pump.atanatizante wrote: ↑28 Mar 2022, 09:47
Maybe Scarbs has better authority and knowledge than me and you believe him when he said it`s a true possibility that the new fuel had affected the plastics which encapsulates fuel pump electronics:

He was suggesting that it was a material compatibility problem of the pump, which is extremely unlikely. It would be very shocking even for an undergrad engineering project.
Pumping E10 fuel or any other liquid you're gonna use the material compatibility charts for that plastic or resin. There are some really exhaustive material compatibipity charts you would be surprised.
The other thing is the pumps would have been tested in the liquid under different concentrations and temperatures, and even inside more aggressive fluids.
It would be extremely unlikley for this sort of part.
