Having said that, if you are alreafdy "Yam connector'ed" up, the cheapest way would be to stick with a yam system, then you'll only need a couple of in-line connectors (could cannabalise your old tanks).


I may as well dump the forward fuel line hints while we're on the subject & i got 5 mins.
On the SR I arranged it so the line went straight to the tank, and used the primer between the "transom connector" from the hose & the engine. Net result - it was a b'stard of a thing to priime if the hose had emptied - those bulbs really don't work well with air. I now have a longer tail at the engine end that goes straight to the engine connector, and have secured the tank end of the hose under the front of the console. I now use the "jumper hose" at the tank, meaning it primes really easily as the bulb is near the tank and so gets fuel relatively quickly. Also saves a messy coil of hose up fwd whnen not in use.

youv'e walked into a minefield, there's loads of ways to manage your fuel, 3 way valve, two going in, one coming out, switch one way for one line and back for the other.
fuel filter, has the option of two lines in and two out added bonus of a filter, don't put anymore weight at the back, your'e transom will be low enough with everything else, tank under the seat maybe, the weight now needs to be just aft of midships.the rule that we work on is KISS, (Keep It Simple Stupid)

Thanks all for the responses - sounds like two tanks are the better solution

I'm beginning to appreciate nothing in the boat world has one best solution but rather each solution is dependent on preference, experience, finances and sense of adventure

Hi jean, you probally seen them anyway but i tried different options and came back to these, picture one is 43 litres and the second pic was 30L.
East to swap over fuel lines as i used Suzuki fuel connnector (like a airline), and with the tanks places where they were made it a superbly balanced set up!!

That's a nice set-up Matt. How far forward is the battery? Underseat or in the console?

So what was better balanced two full 43l tanks or the smallers ones full of fuel? I'm betting you couldn't see any difference?

Very neat Matt - will be dropping the RIB down to Biffer in the New Year to take a look - one of the needs being to sort the fuel tank position - but that looks like a good solution

Many thanks
