The fuel tap on my Suzuki DF2.5 leaks in the on position. The rubber gasket inside looks somewhat damaged. Does anyone know if the gasket is available separately? Or do I have to buy a complete new tap ? The filter attached to the tap has also broken anyway so renewing all might be the best way to go.

Yep same here. Also the rubber disc was swollen and causing fuel starvation.
Got rid of it and fitted an inline filter and an external tap acquired off of fleebay
 
I had the same with swollen rubber blocking the supply. Ethanol in the fuel? I only use super unleaded in outboard/lawn mower/hedgetrimmer now.

Probably very sensible especially with older equipment which may have components in the fuel system which are not compatible with ethanol.

I'm also inclined to use it in my car because of the very low mileage I do these days

Did you know that " Power " a local fuel supplier in the S.East with a number of filling station in East and West Sussex sell only E0 petrol
or that Esso Synergy Supreme+ 99 is actually ethanol free except in Devon, Cornwall, North Wales, North England and Scotland.

I have a couple of classic cars and only use Super in them as well, Esso if poss (SE based). Our rural village garage now only sells diesel and E5 as everyone wants it for their chainsaws & garden eqpt.
 
There is a general consensus both here on other forums, to use premium with these engines. I will do so in future, thanks.
 
I know that this of no help at all to the OP - but I'm going to write it anyway :D
But the fuel tap was leaking in my Yam 2.5 and I used an online diagram to suss it. They wanted £9.70 for the O ring! I took one out my box of metric O rings and job done. Obviously the Suzuki is a specialist unit, but I liked the idea of simply replacing the unit, especially if it is a flawed design.
 
Had this problem with mine. Conveniently I had the Yamaha 2hp equivalent. Fitted that instead , vastly superior fitting, much easier to use too.

Got a part number for that? My Suzuki one is leaking too, and that's just a year after replacing it with a brand new one for a silly price. Definitely not going to buy another of theirs!
 
It sounds ethanol related. These were made before the increase in ethanol was proposed, so the fuel lines are not resistant to it. The hose, tap and filter are likely to be affected and should be replaced with E10 compatible components.

Also affected is the needle valve in the carb. There may be an E10 replacement available, but the best preventative is to make sure the carb is emptied of fuel when you're not using it. Usually by turning the fuel off and letting the engine stall.

Sorry don't know it was just one I had from another engine. Have look at parts diagram on one of the yam sites or go to a yam dealer. Basically the same device, just different design and better.

Unfortunately you are still left with fuel in the carb. The fuel inlet to the main jet is around 7mm from the bottom of the bowl. With e10 water will lie at the bottom of the bowl. The only way to be completely sure is to completely drain the bowl prior to storage

Yes, if you are going to store it for a while. If you're not using it for a bit, it lowers the fuel in the carb enough to not affect the needle jet rubber.
