This is the section which describes how we are able to carry out Conversions from traditional leaded fuels to unleaded fuels. This is a common necessity for many classic cars still on today’s roads and is quite important for the environment too.

Yorkshire Engines can carry out your complete conversion from Leaded Fuel over to Unleaded Fuel without any issues which sometimes present themselves from some methods used by certain compaines in the UK.


This is quite an important and tricky job to get 100% correct and we are happy to say that to date we have not had a single head returned to us after conversion and more importantly, we’ve had excellent feedback from our work.
