Don't be tempted to vent crankcase fumes up to a breather through your piece of hacksawed plate that you're using as a block-off for the fuel pump hole.

So much oil gets thrown up there that you'll wish you hadn't. I stated at the beginning that an electric fuel pump should be engineered in properly.

But if there is any chance of vapour lock, it's better to place the filter between the pump and the carburettor.

This operation is considerably easier on Beetles than nearly any other car. )There are two reasons why mechanical fuel pumps are prone to vapour formation.Firstly, the fuel pump picks up heat, and the fuel lines are necessarily routed close to the hot engine.Secondly, much of the fuel line is under a slight vacuum, as the pump has to suck its supply of fuel from the opposite end of the car, often through the added restriction of a filter, which lowers the pressure in the fuel line even more. So if you move the fuel pump to the front of the car, underneath the fuel tank (there's no point in moving the mechanical pump, because there's nothing up there to drive it, so it must necessarily be an electric one), all the fuel lines near the hot engine run at elevated pressure, and the temperature at which the fuel will boil is a lot higher. I stated if the fuel pump has to suck through a filter, the pressure on the suction line will be lower.And they can even afford to have the filter before the fuel pump for its own protection.It's a joy to realise the intricate details of Good Design in the microcosm of the engine compartment. I have even asked myself if those same Wolfsburg engineers, or their older colleagues some years previously, designed in vapour lock as a backup system for the engine's well being. On more than one occasion (twice, in fact) I have come to the aid of Volkswagens with overheating while driving along the road.
