The product was installed last Friday and was relatively easy. The only issue was the two hoses were extremely tight to fit on to the fuel tubes but with a little dish washing liquid and a lot of persuasion they went on very securely.
I assume this might be in part due to the different original pumps that were used Pierberg, VDO, Bosch etc.
The new VDO fuel sending unit I purchased fit the pump like a glove and the pump worked like a charm
