Redditch Nr Birmingham UK, be a helluva trip for you.

Yeah, it's not a great idea but that's how they went from that point. If the bike was a definite keeper it might be something I'd change but as it is I can't be fussed with it. Making up a 50 mm plate and a normal on/off tap to ditch the vac altogether wouldn't be a huge job. Be a bloody sight cheaper than buying a pingel now too. £200:00 for a fuel tap is just taking the piss no matter how shiny it is.

And we have a winner. The offending article was deep in the 'stuff' bucket.

Maybe it was a deliberately passive aggressive move by someone still pissed off at the Americans for warming up Hiroshima and Nagasaki? Sitting at his desk chuckling malevolently at the thought of people running out of petrol half way to Vegas.

So just to confirm having measured it, I need the 50 mm vac tap. That's confirmed as the later EX type, which I believe was carried over to the EZ.

DK have got two 750s for sale on that auction site, a 1980 with the tap in the middle, and an '82 with the smaller tap at the rear. The more pics I look at online the more convinced I am that it was a model year change between ET and EX to move it to the rear for both the 750 and the 1100. Not that it makes a blind bit of difference to anything 40 years on, but it'd be nice to know for sure.

As is ever the case with Suzuki things don't appear to be as straight forward as a 750/1100 split. I CBA posting them all tonight but there are launch/press release and brochure photos showing 1100s with the tap at the rear and also in the middle. So it appears that Suzuki made a change at some point, fuel surge issues, clearance, standardising tap sizes across the range, or simply 'because reasons'.

I could, but given the price of Pingel stuff now that'd be a last resort. This is for the shelf clearance bike so I want to use as much as possible from stock and only buy what I have to on stuff like a new C&S set.

The 750 44 mm one I think and it has a smaller width filter tower, I can't recall the hole size though. I'll need to check tomorrow as there's a serious danger of mixing up which I need unless I'm looking at it. I should have the tap that came off the tank, but it was stripped years ago so I don't know where it would have been put or if it was binned.

I think that's it, trying to compare how they left the factory and how they are 40 + years later is a bit of a fool's errand. I know the bike the tank came off of is an 1100 and not a 7/11 as the VIN's correct as is everything else. So I'll have a rummage and see if the tap's in one of the boxes, failing that I'll see if I can get a tap, failing both of those I'll just use another tank but that'll mean paint which I wasn't planning on.

I couldn't remember what the different fitment was for the tanks but it does make sense. Threw me a bit as it came off of an 1100, but there will have been a fair bit of mix and match going on over the last 40 odd years.

Someone suggested on FaceAche that the 750 was at the back and 1100 in the middle. Just how Suzuki described them, no idea why but it's on the parts listings at CMS and Robinsons. Export was the big tank and rest of world plus domestic was the small tank. It always seemed odd that the UK got the big tank given how small it is and the USA got the small tank.

ET 'export' large tanks have two fuel tap sizes and positions. 45mm between bolt centres with the tap in the middle, and 50mm centres with the tap at the rear. Anyone remember what the year/model change was?

Along with all the above, keep in mind that you'll be fitting them to a bike that's @ 50kg or 8 Stone heavier than they came off. So spring rates and damping will be way way off, and that will affect braking as well as handling.

The G is 19" at the widest part, 12" at the narrowest (rear) and 29" tip to tail. So it's not going to work unfortunately. I suppose you could go for a fuel cell and then make up or have made a fibreglass cover?
