Carburettor, Fuel and Exhaust

Note: Many members have reported problems with un-leaded fuel, these are common to all classic cars. We have O-rings, tubes and hoses in IMProved materials to counteract this.

The problem is that ethanol is being added to make it so called “environment friendly”. This can however corrode many metals, destroy your fuel tank lining and de-grade rubber based elastomers and some plastics. The FBHVC have researched this and we will do our best to supply components using the most suitable materials available as recommended by them.

WARNING: If you leave your car standing and the fuel evaporates, it will leave a green coloured resin inside your carb. This is extremely difficult to remove!

We have a number of Stromberg and Solex kits in stock fitted with Viton O-rings and tubes. We also keep the fuel transfer tubes for Solex, these and O-rings and diaphragms for Stromberg are available separately.

We now have fuel pump repair kits and brand new IMProved pumps in stock which are claimed to be E10 tolerant.

Cables of various kinds have been re-manufactured, and available in lengths either standard or to order for special applications.

We usually order items in bulk, so that we can pass them on to Imp Club members at a favourable price.
