Fuel cap adjustment and fuel pipe to tank seal

[Tipidave]

Hi again, 
recently the chrome fuel cap has been difficult to locate. There are three brass lugs that need to locate. Is there any way to adjust? I am assuming that the cap needs to breath so as not to create a lock. 
as another issue, the fuel pipe where it emerges from the tank is loose and wobbly and smelling a bit of fuel. The reserve tank lever will not stay in the ‘main ‘ position.
 

Any idea where I can get a replacement ‘top hat’ style rubber insert. My guess is this is hardened, cracked or otherwise failed. 

Thanks once again in anticipation of ideas and help

the fuel cap problem is more likely the tank neck is worn/damaged  and the bayonet flanges dont fit the lugs on the cap

most old caps locking or not are breathers

the dip tube just needs a section of fuel rubber hose cutting to make a olive to fit under the sleeve nut 

you need to remove the tank to get the dip tube removed  

if that helps

Thanks... I will wait until tank is near empty and then get on it 👍👍😀

if you never use the reserve lever action you can use any  plumbing type brass  olive , as it only needs to seal and turn the pipe a small amount 

if you dont use it just nip it up to seal .

one advantage of new tanks is this is all left off.

odd some people run out of fuel all the time others never have in 50years

its a state of mind hic up thingy
