Yes, that is Emil’s fuel system filter but those clamps were what I was suggesting. You brought up the question,”how do you clean the filter”, well you cannot do that, it is sealed and you throw it away if dirty. How can you tell of it is dirty? No way other than a change in the way it runs because it is the fuel pressure regulator as well. In Emil’s system the regulator is up under the bonnet and is adjustable, and the filter is in the boot and is a replaceable canister.
There are so many upgrades ! I wish I could do them all at once!
