I bought these kits a few years ago and only opened one of them. I bolted it up in place only to find the fuel outlet was in the wrong place. It was positioned directly behind my raw water pump. The pumps work on all Chrysler Big Blocks. The pump was bolted up but never hooked to fuel lines or started. Comes with flame arrestor and vent tube. Don't use a car fuel pump on your boat. Marine pumps are designed to route gasoline to the carburetor in the event of a diaphragm failure. A car pump will drip gasoline in your bilge and cause a dangerous situation. I am tired of seeing these sit on my bench. My loss is your gain.
