Hi Guys,
Have any of you experienced cavitation (aka vaporization) due to 90 degree fittings on the supply side of your pump?
I'm putting an SDS injection system on the -8 and just bolted in the beautiful twin pumps. They are a tight fit so I have 90 degree fittings on intake and output. To make it interesting, I'm also using an Andair valve with 90 degree fittings. The tanks of course have 90 degree fittings coming out of them.
So tracing the fuel from the tank it will go through five 90 degree bends: at the tank exit, the valve entrance, in the valve, the valve exit, and the fitting into the pump.
I can eliminate three of the five bends by drilling four more holes in the floorboard to reorient the pump and getting straight connectors into the Andair. I might want to use mogas in the future, but this is just a four cylinder engine. The fuel flow can't be that high. Am I obsessing?
Cheers,
Bob
