Grey tank cap and seal (2 Viewers)

[Colin McCourt]

I have a 2019 Coral Supreme and have unscrewed the cap underneath to try and give it a good clean. The seal around the cap in one area was squashed in and I reseated it. The end of the thread, which was very thin, was broken ( 1cm) as well. Having done up the cap and filled the tank to test, it is leaking slightly and I can’t seem to tighten it any more when lying under the van, which isn’t raised. Think I may need a new cap/seal. The cap is red. Does anyone know where I can source a cap and/or seal? Another solution may be to grease the cap before putting it back on.

You could warm the seal in boiling water so it is flexible when screwed up, these should remove the misshapen seal from when it was nipped. Which thread was broken, cap or tank?

Saves having to do a big empty.

Cap. It’s only the last 1cm of the end of the thread which was very thin. I don’t think that is the problem. I suspect it is the seal as the thread just allows you to tighten the cap against the seal. Your idea sounds good so will try that tomorrow.

Can you add a thicker washer on the cap ?

Did this and reshaped the seal. Also added some grease and all good. No leaks now!
