You've lots of good advice and I would suggest you do the following, this will tell you lots of things I think everyone should know about their fuel systems.

Starting from scratch:

First disconnect the fuel line and using the primer bulb try and suck out fuel into a container (I guess the 10 litres you put in afterwards would be enough). If plenty of fuel comes out then I guess there might be another reson for your motor cutting out. If none comes out go to the next step.

Physicly measure the amount of fuel in the tank. Take out the sender unit and insert a piece of rod to get a measure on how high the fuel level is referance the bottom of the tank. This will then tell you if the fuel pickup is on the bottom of the tank or not. If the level is high then it might be possible that the pickup tube isn't on the bottom or something is obscuring the tube preventing flow.

If the level is low, you're empty.

You could also remove the pickup tube at this point and see what you've got.

I would suggest that you empty the tank completely and note the amount of fuel that it takes to fill in one go. This will give you a good idea if you can get the full capacity or not. Bear in mind that the boat level on the trailer might be different from that in the water.

If the pump keeps cutting out then either reposition it in the fuel filler neck or get a bigger tank breather. The pump often cuts out when I start to fill mine up. This is because there is a bend in the tube that causes the fuel to back up a little. If I pull the nozzel out a little it fills without problem.

Hope this helps,

The Searider Cruise boys where at the Folly on Saturday, did you not see all the RIBs just North of the Folly Pontoon?

That's a shame. Next time perhaps

Just follow my instructions, it's a little longwinded but will tell you everything you need to know.

Will do & I don understand what you mean to do . I've just toped it up as far as possible and managed to get 120l in - so either it is a smal tank , or the pick up is missing around 60l worth. I know all tanks have an unusable amount & have always been paranoid about it as its somehting I learnt when flying - never trust the gauge. But was stunned it ran out after using 95 ( according to the fuel used gauge, which seesm pretty accruate compared with the LPH and what I have been doing. )

So tomorrow night the sender comes out and I 'go in' - I have already stunk the house & car out with petrol so it cant get any worse !

Thanks again for all the info - As an aside I managed to upload a few videos to youtube :



etc

BlackRoady,

Why don't you run you tank down as far as you dare then go to the pontoon and moor up. Then use the primer bulb to draw out any remaining fuel into a jerry can. Once you have done this re run the calibration process on your smartcraft guages

I liked the Videos, perhaps if you have the time you could post some pictures in the Gallery of the rest of the RIB, I'm interested in seeing the cabin and cockpit area.

You may find it easier to 'go in' via the filler tube fitting, rather than the sender.

As an aside, I find the Smartcraft fuel flow and level gauges to be very accurate, so I'd be surprised if this is your problem.

A little low

My Smartcraft "fuel used" trip always says i've used a little less than I manage to get in the tank when I fill up - perhaps a 5% difference.
