Welder - I am really not sure what was the actual cause cause but I want to make sure there is no strain in the IP from inadequate incoming fuel pressure . I will heed your advice ( pressure guage, run both fuels through HE) but am concerned about problems with hot diesel causing problems for the IP during those times when t can't use WVO ( because of supply problems ) . - Thanks

Shane, what PSI does "XX" represent? The 23 Amp unit shows XX PSI.


"XX" represents whatever the application needs and the pump is preset to from 10-80psi. So one could order the 23amp version at a preset pressure up to 80psi and it will still be covered under warranty.
The 8amp is currently only being warrantied for vo at 10psi.

Adding about 5-10% of veggie should easilly remove any risk of damaging your IP by heating the stop/start fuel. Apparently veggie has even better lubricity than bio.
