The item you are viewing is a professionally rebuild SU HIF Dual Carburetor assembly for an MGB 1.8L engine. It also includes an accelerator cable. I purchased it in 2017 for my 1979 MGB as a replacement for my Weber Carburetor and manifold assembly. I never installed it on the car and sold it in 2018. The buyer was not interested in purchasing this assembly with the car. The care that went into this rebuild is very impressive, I do not believe the photos do it justice. The air filters are not included because I never purchased them. I also have another EBAY listing for the exhaust manifold (non-Catalytic Convertor) that is compatible with this unit.
