petrol cap problems ?

[hillmanimpman]

i brought a new petrol cap at a autojumble for the morris marina but i am missing the adapter that the cap locks on to does anyone know where i can buy an adapter as don't want have to buy another cap?
this is the same cap as mine but without the adapter

Have you tried the manufacturer?

An important lesson here is always check that what you're buying is complete.

Probably a stupid question but have you tried the cap straight on to existing filler neck. I can't remember exactly but thought the Marina cap had internal flange already. Some cars such as the Minor & Austin 1100 had external fitting caps which needed the adaptor to be fitted. Just a thought but I am sure you will have tried it.

I remember from our old Marina, we had the same make of cap & the adaptor was necessary; can't recall why, I was too young to pay that much attention - possibly the original cap fitted on lugs on the outer rim, which isn't practical for locking caps?

there only external locking point because the marina was stripped for parts for moggy 1000 luckly i had alot of the missing bits so fitted them. this only thing i haven't got in my spares box. but i have a look on my very rotton spares allaggro estate see if there adapter on there

Allegros don't need adaptors for locking petrol caps; none of my fleet has one.

my allegro has but it is a series 1 1974

Hm; my 1974 has the same filler neck as the other cars, so even that adaptor would be unlikely to fit the Marina. Can't hurt to try I suppose.
