I have a 1991 Crestliner Viking 170. I can no longer pump fuel from the underfloor permanent fuel tank (I've tried multiple bulbs) which leads me to believe either the underfloor fuel line is fouled, the anti-siphon value is bad, or the fuel pickup tube is plugged.
But in order to check out any of the above, I need to access the fuel tank inlet value. Even with the aid of a fiber optic inspection camera and removing all of the seat bases, I still cannot find the under floor location of the damn value.
If I knew where the value was, I figure I could cut an access port to troubleshoot. Alternatively, it looks like I could remove the floor but that looks like a real PITA which would also necessitate removing the console. I'd be happy to hear informed opinions on which is the better route.
Attached are bow and aft photos of the floor. If it helps, the tank is 22 gallons with a 4" depth at the fuel sender (I've searched in vain online to find a similar shaped tank to provide a clue but this shape seems to no longer be manufactured). The fueling port is on the port gunnel (visible in the bow photo).
Many thanks!
