Re: No Start/no injector pulse

Glad to hear it's back up and running - that's a LOT of fuel washing down the cylinders - I'd make sure to run it and get the engine oil hot to evaporate any remaining fuel out of the crankcase

43-47 is the spec I recall - you'll be fine pressure wise with the 50 PSI fuel hose as they usually have some margin built into the design.

Get the right hose - that hose submerged in ethanol fuel constantly doesn't last real long in my experience - you'll be replacing it in about 2-4 years... Get the new ethanol "flex fuel" hose.
