I am currently rehabbing a 1994 SN, taking off Protec and bringing boat back to life. I have replaced the electronic fuel pump with the mechanical pump. In replacing the fuel line from the tank, I thought "why not use the electronic fuel pump to pump out the bad gas?" But in hooking up the fuel pump to the old line, and wiring to the battery, I first got a splattering of (small amounts (teaspoons at max)) gas. I waited a minute or so, and nothing, so I reversed the wires (thinking I might have wired it in reverse), and still nothing. I put my finger over the exit of the pump.... (which is in the gas tank). Nothing. No gas, and also no pressure (doesnt feel different either way I try to get gas to come through (reversing wires etc). I added 1 gallon of gas to the tank (to see if I was just out of gas), but even this gallon of fresh gas doesn't pump out.
Is there a screen in the bottom of the pickup line in the tank? I dont want the new carberator getting bad gas, so before pulling the tank to check (and having to mess with the filler hose and vents) I thought I would ask advice. Thanks! Erik |

Have you tried to siphon the remaining gas out?

I have siphoned with a small hand pump. Got 4 gallons out of the main filler line a month ago. But then I couldn’t get any more. Figured it was my small pump, but I wondered if that was all in there. I’ll go back to that, but with larger hand pump. You’re right. Just figured there might be a screen that might be clogged. When I first disconnected the gas line from the pump (before removal) I got nasty whitish sludge gas coming out of the line. I hand pumped a few ounces out of the line before it stopped coming. It finally had normal looking gas before it stopped. But that led me to think there might be some other obstruction. The gauge reads full. I don’t believe it (as I know -4gal atleast) But tank is yellowish, and I can’t see if there is any in it. The pouring new gas in yesterday, and it not coming out when turning on the pump, made me think something is obstructing. Siphoning it is |

Take a short piece of hose and hook it to the electric pump, put the other end in a portable gas can and see if the pump is pumping. If you use a piece of clear hose you can watch the gas move up the suction line from the gas can. If the pump works, then you can look at the anti siphon valve where the fuel line exits the tank and unscrew the fuel pickup line from the tank and see if the strainer is plugged or if maybe the suction line just plain fell apart. Click on the link below for some reading and a picture of the anti siphon valve. Start at the top of page 5 http://www.correctcraftfan.com/forum/forum_posts.asp?TID=49697&PN=5&title=2002-ski-nautique" rel="nofollow - link It's good to check the valve and line now anyway while things are apart  |

Thanks for the advice! I had a collapsed fuel line, once I cut the line on the other side of the collapse, I was able to pump gas out. Got it all out! So the old fuel pump works great as a way of getting old fuel out Thanks again! |
