Looking to make 700WHP+ on your N54 powered vehicle, need the fuel to do to so, and don't want to spend a ton of money? Look no further than the PFS bucketed "External Series" fuel pump upgrade! The external series takes our already best on the market bucketed design and adds a 3/8 Quick Disconnect bulkhead fitting to the top hat which allows you to run the secondary pump independent of the factory lines. This allows FULL FLOW from the second pump unhindered by the factory jet pump, siphon, fuel filter, or fuel pressure regulator. We add a few more options to get the fuel flow needed to make your N54 king of the kill!  Note:  PFS external series are normally custom builds -please allow a few extra days between ordering and shipping, and don't be afraid to shoot us an email detailing what the end use will be!

(If ordering our PFS PI kit, we can work with you to get the proper line configuration so you are not buying multiples line sets)

(Custom line kits can be ordered, simply let us know your needs, and we will build you a custom set up)

    Modern fuel systems no longer use rubber components because of their incompatibility with modern enhanced pump gas which contains ethanol and other solvents such as toluene, xylene, and MTBE. Unlike flex tubes, rubber hose will break down very quickly when exposed to these types of fluids. This will allow vapors to leach into the atmosphere and cause the hose to swell and burst. Rubber particles may also contaminate a modern fuel system causing jet pumps, siphon pumps, check valves, regulators, diverters and injectors to fail. When replacing a fuel pump in a new fuel system, it is imperative that a new fuel tube be used. PFS uses fuel tubes in all of its late-model fuel pump assemblies to guarantee compatibly and reliability with the factory fuel system.
