What damage does ethanol in fuel do and how to tackle it?

[taylormj4]

Hi Folks,
As the title, what gets damaged by ethanol in fuel: E5 / E10 or worse?

Is it just rubber components like fuel hoses or are there other areas that we should look to replace (fuel pump, valves, inlet manifold seals)?

If things like fuel pumps get damaged, if we replace with a new one, will that just be the same as it's old stock or do all components sold now have to be ethanol-fuel compliant?

Or are you all just using E0 fuels or additives ?

I've always used V-Power(previously Optimax) in my TVRs and now I use V-Power in everything including BMW , Lawnmower and Rotavator ) My understating is Ethanol is hydroscopic and absorbs water when left standing ... since filling my tanks is infrequent I suspect more prone.
In addition to it attacking fuel lines.

This in a nutshell
Secondly as Tvr were mapped on super or 99 it’s not good to be using a lower octane fuel if your going anywhere near high revs.
It’s fine if your cruising around mind
