Chief Alen, heh, there. Not sure if you remember me but I installed a pertronix dizzy in my bayliner 2150 sierra sunbridge with a omc cobra 5.0L. I need some advice.....OUCHÔǪ hate to admit that....Finally got the outdrive shift cables adjusted correctly. found a factory defect and corrected it. shifts great now with little effort. But....took the "ole girl" out and it was hesitating out of the hole. top wot was 4300rpm at 38 mph swinging a 15├ù17. SoooooÔǪtook a look at the fuel and the carb. It was a 6 year old rebuilt carb but I pulled it anyways. Then decided to pull some fuel out of the tank because it smelled pretty varnish-ee, know what I mean? Made me think of day old stale beer cans.... Inline fuel filter was a little black but not plugged. So I when I put my little electric fuel pump on the fuel line, I got 2.5 gallons out and the fuel stopped flowing???? HUH?? I blew on the fuel inlet hose with 20 psi and nothing. Nothing would pass, so increase pressure to 60 psi. and it feels/sounds like the air is passing into tank pickup tube at the bottom of the tank.
So Looks like the problem is in the "check valve" hose barb that is located on the top of the tank that goes into a 90 degree fitting. Is that really a check valve??? Is the check valve suppose to prevent fuel from coming out or going in?? Doesn't make any sense to me. Why would you put a steel check valve in a water exposed fuel system???? The rubber hose is about 12" long and rises about 6 inches to the water separator filter. Does it prevent fuel from back flowing into the tank????? Then have I blown the check ball into the pickup tube with compressed air??? Or is it just gummed up and need to be replaced?
Does it prevent the tank from siphoning out, then how does the pump pull fuel through it? Any suggestions beer influenced or sober would be helpful in understanding what is going on here. Where I would get one to replace the existing one? In automotive we use a check valve to maintain the pressure in the fuel lines to make starting easier but the pump is in the tank and pushes fuel through the valve. These valves are usually plastic and stainless steel, not aluminum that will corrode. Huh???? what is going on here?? why would one install a check valve to keep fuel from coming out of the tank? isn't that what the fuel line is for??? to take fuel out of the tank? Only thing I can figure is that this must be a "political" valve..... you know what I mean, some politician decided that his brother in law needed a business making wrong way check valves?
