Goal is to have an extremely robust setup that can manage fuel of dubious quality whilst preserving the integrity of the system

But- I’d be the first to admit I don’t know a great deal about fuel systems

I can’t work out how to add a picture as when I try the forum software says “images not allowed”

Ok, doesn't appear that you can tell the software that this is a link to an image, so I'm afraid it won't display it but you can click on it to see it - this is not malware I promise.
