I have an MoT advisory relating to the offside lower wishbone suspension bush on my classic.

What's actually involved in replacing them? Does it involve using a press and are the bushes in half?

I'm wondering will it be worth simply changing the wishbone direct from Caterham that has the bushes already fitted?

On a separate note, just giving the car a service & cant locate any form of fuel filter. The car is running a bit lumpy so thought I would replace it however there is no filter from the carbs to the pump & tank unless there is one in the tank which is not practical!

It's a 1600 Vauxhall engine by the way. Cheers as always

With the bush, it depends which one...
There are a couple on the wishbone.
Personally, I swapped to Powerflex all round - way better.

No idea on the fuel filter.
I have one in the Facet fuel pump, as well as in-line.
