Fuel line valve question

Mark

I dont have a twenty ....but things to check in general if you havent already [img]/images/graemlins/wink.gif[/img]

Does the vent work (vent blocked , vent hose kinked etc)

Fuel delivery line (kinked/ blocked fuel line, primer bulb direction and operation, filters clogged ...Also See if fuel comes out of the tank without the fuel line hooked up to the tank, etc.. )

Fuel pickup in the old tank ( is that clogged inside the tank as a result of above (no fuel out of tank when lines are removed [img]/images/graemlins/confused.gif[/img])

Doesn't sound like anything with the motor if the engine runs on an aux tank.

Start eliminating things one by one .... sooner or later you find something ...if not a combination of issues that will not allow good fuel flow


Edit:
After re reading your post ...how old is the fuel i.e. Has it turned to VARNISH !!!!

One thing we discovered on my father's 23 Sceptre a couple seasons ago was a small screen inside the 90 degree fitting that comes out of the tank to the fuel line. After 20 years, it was pretty gunked up. We weren't having any fuel delivery problems, just doing some inspection and came across it, but it may be worth checking out.
