Don\'t know if anyone can help me on this,
I\'ve got a Mazdaspeed AST for my car, but the supplied cap is rated at 1.3Bar which is way too high!
The factory cap will fit but it\'s a very tight fit which makes me think the cap will not work properly.
Does anyone know where I might be able to get hold of a 0.9 Bar replacement?
I\'ve noticed Re-Amemiya supply their AST with a 0.9 Bar cap but can\'t seem to find it on it\'s own, only with the kit.
Thanks,
Andrew.
Cant imagine the tightness will affect it, as its regulated by the spring not fit.
Sorry dont know who will supply just a RE cap
Yeah not too sure myself Gary.
The rubber seal is about 4mm too big in diameter for the filler neck so I have to push to get the cap to fit.
My concern of course is that the spring won\'t be able to operate the cap seal, it will get stuck.
