Ok, so I got a spare tank off Damon and thought since it was off the car I might as well make sure it's future-proof enough to outlast the rest of the car. The outside is all POR15 painted, which I might just go over, but I thought I might seal the inside with that POR15 tank sealant stuff too. Anyone had any experience of using this? I'm guessing Ian has, lol.

Plus, the filler hose could maybe do with replacing. Certainly the little overflow/breather pipe has cracked, though this is easy to replace as it's just flexi 15mm fuel hose. The filler neck hose is the problem; it's 48mm diameter and proper fuel necks with bends only seem to come in 45, 51 or 57mm diameter You can get Samco silicone "fuel" hose in 48mm but it states it's only for short-term exposure to fuel, not for permanent immersion or transfer of it. The bend in the original pipe is gentle enough that you could probably get away with a straight run of silicone pipe without it kinking, but I don't want to swap in something that's going to degrade quickly. The original isn't in too bad a nick, but is it worth taking a chance on putting something back that's probably already 30-odd years old?

Finally, gaskets... is there any way of discovering parts numbers for the cork gasket on the lift/return pipe plate and the rubber gasket on the fuel sender? Is there like a Mazda parts list online anywhere?

Thanks as always in advance

Oh, and finally, finally.... found this little filter thing rolling around loose in the bottom of the tank. I'm guessing it should be attached to something, lol. What and how?

Think you must ask Damon

Never used por15 inside a tank, only outside.
The filter thing goes on the end of the pick up pipe... when you remove the hardlines from the tank, you'll see which one it goes on, if not, check out the thread on that silver car I scrapped.
Personally, I'd reuse the original filler hose, I know what you're saying about age but I reckon it's got more chance of leaking if you try to make your own... just my 2 cents

Really?

They're American?

The filter thingy goes on the end of the supply pipe.

You can get cork gaskets from Mazdatrix and Black Dragon.

This is what I figured, but I'm confused by the little black plastic clip thing... there doesn't seem to be anything for it to clip to It clearly only fits on the one line in the tank because the other is too small a diameter, but it's hardly what I'd say a tight fit. Is it really as simple as when it's in place there isn't enough clearance between the bottom of the filter and the base of the tank that there isn't space for it to fall off? Seems weird


I found this on Ian's silver car build thread



but I dunno if that helps. Is that really how it fits?

By the way, is this the same car that the windscreen surround has rotted through, Ian? It almost moved me to tears going through that thread thinking how cruel it's turned out

yeah, it's the same car ................................still, every cloud and all that

Ian,

Did you not think of getting a roof cut from a US car and get it shipped over the pond ?

Surely worth looking at ?
