Process West Anti Surge Fuel Tank - Twin Walbro 460 - Subaru WRX MY08-14 / STI MY08-14



Process West's fuel anti-surge system is the ultimate in fuel delivery for your G3 WRX or STi

The system sees the pump (or pumps) mounted internally to an externally mounted anti-surge vessel made from  6061 billet aluminium. The vessel is mounted just above the transmission cross member... This is not an in-tank system.

One of the main objectives when designing the system was making sure the system was easily upgradable when the need for higher fuel flows is required.  This “basic” system comes installed with 1 x Walbro 460 pump and is a simple plug and play option. Alternatively we offer a twin Walbro 460 pump system. 

When purchasing a twin pump system it is worth noting that the system concludes at the pump outlets of the surge tank. From this point on you will need plumb into your existing system.

When a second pump is added to the system the flow is greatly increased and the factory fuel pressure regulator is unable to control fuel pressure. At this point you will need to install an aftermarket fuel pressure regulator. For this reason all twin pump systems are configured with -6 AN fittings at the pump outlets to enable ease of plumbing into after fuel rails etc.

This system comes with a pre-assembled wiring harness. Wiring installation is very simple and only requires soldering of 2 wires.
