I have done the breather mod on my car already but not the MX-5 valve. I am not that keen on the MX-5 one, due to availability of the part, adding spacers and jubilee clamps on the outside. So I am looking at combining both mods into a single off the shelf filler neck...
I have a used filler neck and can use for parts to make mine but wondering if new parts are easily/cheaply available to save me cutting up my spare filler neck.
So wanting to know what other cars used the same filler cap/neck as the +2?

I just noticed Robinshaw & Ross calls up Jensen Healey as using the flip type fuel cap.
However, these pictures of Jensen Healey parts shows a bit different looking neck and rubber attachment. The Jensen Healey neck may work better for you?

This link has a better picture of what they claim to be the new Healey replacement part (cap and neck). A similar looking locking cap and neck appear on page 80 of the current Car Builders Solutions catalogue.

Thanks Stu, the jenson part does look right but it's a bit pricey for my needs.
I also found the Norton one, with just the neck topper which is exactly what I want but it listed as 1 3/4" ID and the lotus one is 2 1/8" ID.
I've gone and ordered the bits and plan to use the old one I have here to convert mine. I was just hoping to find cheap new bits so other's could copy and fix two problems with one neck

Chaps, could someone clarify please, I want to do this mod and can find MX5 MK1 and MK2 filler necks on eBay. Which one do I need please? Is there a difference from the point of view of just wanting to scavenge the valve? Thanks.

As long as it has the non return valve it doesn't matter. I fitted mine in the neck of the tank, turned up an ally collar that the valve fitted into made the outside of the collar a snug fit in the tank pipe with a small flange same size as the outside of pipe.

Good day!
I am getting ready to perform the MX-5 check valve into my 1968 Elan+2.
I was wondering if you had a spare mounting ring for it? From what I've seen, your solution is the cleanest way to go. I really do not look forward to cutting up a MX-5 pipe and using reducers.
Thanks!

No sorry, I just made the one ring. I made it out of some ally, turned it to be a good fit in tank neck with a small flange to stop it going into tank, and made the mx5 pipe a good fit in the ring, I left the mx5 pipe slightly long so I could bend the tabs over to ensure it didn't drop into the tank.

Thank you for the quick reply! Looks like I will be sawing a MX-5 pipe after all!

Thanks for the list of places to obtain the valve.
I'm going to go to E-bay and look at the availability of the fuel filler pipe, just in case I have to go that route.

I got my mx5 filler pipe from an online breaker yard. £8.00 bargain.
