Fuel Starvation Problem

[Capt. Bob]

ok makes some sense. i thought it was just there to keep the motor primed with fuel so it was easier to crank since it wouldn't let fuel drain back to the tank after the engine was shut off.

That's the job (at least half of it) of a properly functioning  (and correctly positioned) primer bulb.

It is my understanding that tank builders include the anti-siphon on all tanks, based upon gov. regs. for inboard engine use.

They of course can't ascertain specific use without notification....so they're included on all to satisfy regs.

When ordering a new tank for outboard engines....instruct the builder to delete the anti-siphon.

I was thinking about taking it out (assuming I have one) and leaving it out. I think it would eliminate future possible problems.

I was looking around at my fuel lines yesterday. from my rear pie-plate I can reach up under the floor and can feel that the lines run through a bulkhead there with a securing clamp wrapped around them and seems to be mounted to the underside of the floor. im debating leaving that man line from the tank line alone as it feels to be in really good shape, and just replacing all the other lines

Are you running ethanol fuel or non ethanol fuel?  If you are running fuel with ethanol in it I'd replace everything.  The reason is the ethanol will attack the inside of your fuel lines and turn them to goo.

I run non-ethanol every chance I get.

I took the fuel line off the shut-off valve today (what a PITA, it was stuck hard). tried removing the shut-off valve but couldn't get it to budge with a 3/8 ratchet and socket and a crescent wrench on the pickup tube. after that didn't go well I decided id see how far in the valve I could stick the straw off the wd-40 can in there. I held the depth with my finger and put it ont he outside and it goes to over halfway back into the far side of the pickup elbow. soooo im figuring that I do not have the anti-siphon ball. that main fuel line is attached to the hull hard, I tried pulling it while I had it off and it didn't budge AT ALL.
