I'm afraid I don't know what is in your boat. If it has a "standard" Moeller type fuel gauge fitting you can get a replacement from Moeller that has a fitting to allow you to out on a bit of hose as a pick up.
You have to be careful, there are two part numbers, one allows a return only, the other will work as a pick up or return.
It's a bugger to find on the web site.
Ah ha! Found it, first try.
Can a return or pick up be added to my fuel tank
Yes, with a Moeller sending unit with a return built into it. (035724-10 just a return)(035789-10 pick up or return).
