Fuel shut off ideas!!

[Chris Hays]

Looking for some ideas on a way to shut off fuel supply from the tank to the fuel pump conveniently and safely, as ive had previous bad experiences with gasoline being left to sit in carbs over a period of time. My idea is when im done with the boat for the week/month, that when im done running it on muffs in my driveway, i can shut off the fuel supply from the tank and let it run the pump, lines and carb dry of fuel. That way i can prevent bad fuel issues. Ive used Stabil etc but would rather just do it this way. My questions are will i damage the pump by restricting the suction line, and what should i use as the actual shut-off? Its on a 3.0l Mercruiser btw, 1990 MY.

Re: Fuel shut off ideas!!

you could use a manual shut off of some type, look thru the brass fittings at an auto supply store,or, an electric line lock such as is used in a dual fuel set up( gasoline-propane)

from past experience it's not a good idea to run it dry the diaphram in the fuel pump could dry out and dry rot same for the carb the accelerator pump could dry out. Why do you want to run them dry if it is because they sit for some time why not use some stabil? thanks
