Wanted - 202 bayonet fuel filler cap

The fuel tank I have for the 202 didn't come with a fuel cap, so I need to track one down. It's a bayonet type but seems to be an odd size and I haven't been able to find anything so far with the right dimensions. I've attached an image, which shows the filler neck dimensions so hopefully someone knows a source (nozem ?). I've sent an enquiry to Bob Wright, but no response yet.

The parts list I have shows that early models (1964 or so) of the 202 had a flip up fuel cap and I've found a few of those available in Italy. If necessary, I'll modify the tank I have to accept a flip up type, but would prefer to get a bayonet type if available.

TIA

Actually Nozem's restored 202 shows a bayonet fuel cap. Hopefully mine will look like this one day :)

did you only search for an original Gilera part?
Maybe you will find something fitting in the range of other oldtimers, traktors, boats, garden machinery....

good luck, Joachim

Thanks for the reply, Joachim. Yes I've done extensive searching. There's a 50's era volkswagen fuel cap that comes close, but the spring steel bayonet is too short. I'll keep searching, or perhaps Bob might get back with good news, but if worst comes to worst I still have the flip-up cap option, which I actually think looks better anyway. Here's an early 202 tank with a flip up cap....

Hi Lambs,

Sorry for the late response! It took me a while to get to my bike in these strange Corona times... *durchdreh*
I have checked the fuel cap of my Gilera 202 and I think that you are searching in the right direction.
Because my bayonet cap is marked with Patent Blau, this probably is the same as the VW cap that you found?
But as you already found out these bayonet caps were available in various dimensions.
I have taken pictures and measurements of my fuel cap, I hope this will be of any help.

The fuel tank in your previous post is actually of a Gilera 175 Giubileo Extra, not a 202.
The 175 models had the flip up fuelcap, I think that the 202s always had a bayonet cap.
Late models of the Gilera 124 (1965 and up) also had the same type bayonet fuel cap fitted.

Good luck!

Blau is simply a brand.
Producing fuel caps since.... many years
I think they are still alive

ciao Joachim

What's interesting is that the 202 factory parts book that I have shows a flip-up style fuel cap as the standard part (PN 27808), see attachment. The parts list was printed in 1965 and 202 production started in 1964 (I think) so maybe early production bikes came with the flip-up cap (??)

I must admit I like the idea and looks of the flip-up fuel cap and it would be simple thing to mod the tank that I have to accept one. My bike is an early one based on the frame and engine numbers.

Decisions, decisions..... :roll:

Great stuff Lambs, I never noticed there was a flip-up cap in the 202 manual!
This way we keep on learning new stuff about our Gilera's every day . :kacke:

I also happen to have a Giubileo 175 fuel tank over here.
It has the "Supercortemaggiore" flip-up cap, brevetto 59316.
Notice that the fuel cap of the 175 fuel tank is about 5-7 mm smaller.
So if you decide to go for a flip-up cap, be sure to get the right diameter.

Greetings,

Supercortemaggiore seems to be a reference to a type of AGIP fuel:

Looking at the Blau website it seems their type B50 fuel cap will fit my tank, specifically the B50 MBE-OENTL type:

Now I have to decide which type I go for - bayonet or flip-up......decisions, decisions :roll: :D
