The fuel system was actually simplified by the fact that the car had factory installed 3/8inch pump-feed and 5/16inch return alloy fuel lines. All that remains is to install a non-return Holley pump, a Surge Tank to prevent any air entering the high pressure side, High Pressure Pump and Filter. This system also allows the use of a Carburetor later if needed. |

Pressure Testing The Fuel System. SurgeTank is constructed from an old aluminium fire extinguisher and fitted with a low pressure gauge for checking any pressure build up (Holds just over 1 Litre). Left pump is a low pressure electric pump to simulate the engine mechanical pump. Next to that is the Airtex A8228 high pressure pump feeding a filter and then the fuel rail input. The system was tested to 100PSI with no leaks and no pressure in the surge tank. |
