Hi all

Does anybody know if there is a repair kit to repair a fuel tank tap for the CB400F (m20 thread)

Mine does not fully shut off and £80 for a complete new tap from DSS seems a tad steep

Plenty of cheap m16 taps about on eBay but no m20 type?

Many thanks in advance

Best wishes Al

DSS sells an o-ring repair kit for the fuel taps.  It's two o-rings placed side by side as the full thickness o-ring is no longer available. I used them on my fuel tap and it cured the leak. Make sure you use some rubber lube on them though otherwise they bind making the tap very difficult to turn.

Hi Dave

There no actual external leak from the tap but fuel is still passing the shut off valve to the carbs

I am reluctant to take apart just in case anything rubber fall apart but I think a seal like this needs replacing?

I had the repair kit from DS but retained the original large O ring as I wasn't keen on putting two O rings in. If the tap is leaking externally by the lever you pretty much have to use the two rings. I cleaned all the staining off the plastic centre part - so far it hasn't leaked. There are two O rings in the kit as the ones supplied are too thin. It's a shame they are not supplied with one ring the right size. My tank filter was in shreds so it was worth the cost.

Hi all

Thanks for the info so far

Ok as I read it there are just two orings that will require replacing and not a big rubber disc with holes in?

Is that correct

Many thanks. In advance Al
