    Could be but I suspect that whomever is performing the service isn't properly priming the fuel system. Do yourself a favour and stay away from ether. That stuff will crack rings and damage the liners (takes the lubricating oil out of the crosshatches).

    Get a section of clear plastic hose (Milk house hose) and put inline from existing hose to your fuel filter. or where ever you want to look. Low pressure line.

    You mean when they pull your fuel filters off? You’re going to lose prime if you have spin on filters. I’ve never messed with a Davco. My secondary filter has a valve on it to keep the line to the injectors from back flowing.
