All in one unit with a longer filter/reserve than standard,.Italian made, .Some other taps have no ethanol resistant o ring,.Sold many for two years now.Never had an issue with fuel tube.



Hi Shaun,

Those are exactly the ones I have.
I only had the problem on one side of the S. I thinks I'm using Cavis green fuel line.
No issue on the race bike using the same replica taps.

Actually my favored fuel Petcock as they are very easy to dissemble and clean: however, the inlet and outlet tubes are weak (Tend to break off) and corrode the threads when using modern Alcohol % fuels - For maintenance, I suggest you unscrew the inlets and outlets every 2 years, lubricate and use Teflon tape.

Aside for maintenance, you can depend on these Petcocks to stop the flow of fuel before it trickles over your pistons, wiping the bores and saturating the crankcase oil. Dellorto fuel bowls float needles can't handle to stop gravity feed.

Always Shut Off the Petcocks when you shut down your Breganzie - Even for 5 minutes ;o)

I never used the reserve stack ='s Missfire before you're empty.

Good advice there Ron.

I'm baffled that for probably three decades of very regular use, main means of transport, touring, racing, commuting on my SF, I NEVER turned the fuel taps off and never once had the float valves cause my cylinder/s to flood. I agree it makes perfect sense to turn them off when stopped, and I'll try and make a habit of it when I get the spesh on the road, but seriously, never once turned mine off.

Same here: either “on” or “reserve”. Only used to use “off” when removing the tank or carb(s). Can’t say any of my mates did any different back in the day either. Only seem to be having problems with taps these days because I keep turning them on/off and am probably wearing them out..  (bolt)

The difference is that today the parts are 40 years old, worn and /or damaged.

I have drained 8 litres of black 'water' from the sump, a mix of oil and degraded fuel.
Owner left the bike for 5 years with the taps switched on.
Luckily all the fuel had found it's way into the sump.

If the combustion chamber is full of fuel conrods WILL bend.

Exactly. The risk of the fuel tap leaking is undefinable, but the consequence of the risk is huge and expensive.  So why not just switch em off and lessen the risk?

Having said that, I'm working on getting a new-ish triumph scrambler at the moment. Has been stood for a while. Fuel tap firmly off, but ALL the fuel was in the sump. Off sometimes ain't off.

On the later model bikes [90's] with carbs that don't have a fuel tap to turn off,  does anyone fit petrol taps?

They're already fitted aren't they?
Depression taps of some sort, or electro vanes.

I searched electro vanes and depression taps ......... I'm still confused.

Do you mean vacuum-operated or maybe now, electric powered Paul? Fuels injected and pump operated have no probs.

The ZZR250 has CV carbs and the vacuum type fuel taps and the fairing makes it as good as impossible to drain the bowls when I park i knowing it could be months before I want to use it again. Just means I have to turn it over several times for as long as I dare each time to get fresh fuel into it (assuming the stuff in the tank ages better than the stuff in the bowls - or else the stuff in the bowls evaporates away?). Eventually it starts - huge testament to the tiny battery that often sits untended for 3 months.

It's the Dellorto float needle that tends to leak into your engine not necessarily the tank petcock valve . To ensure it does NOT happen always shut off your petcocks when you shut down.
