The Nuke Performance 2G 3 liter fuel surge tank can be run in a dual or single internal pump setup. The two pumps combine to output into a single 7/8 NPT outlet which can supply steady fuel flow for over 1600 HP. Fuel pumps are mounted with the billet internal mounting bracket. A 7/8 NPT to AN10 fitting is supplied. With this tank you minimize the risk of fuel starvation when running at low fuel levels and where the fuel system can't cope with the extremely hard driving such as drifting, drag racing and track days. By generating higher g forces, fuel can be pushed to one side or sloshed around too much causing starvation to the high pressure pump that supplies the fuel rail. This is a potentially catastrophic situation, particularly in turbo applications, but also on naturally aspirated engines. With a high quality fuel surge tank like this designed for use with top tier pumps, fuel starvation should never happen. As is the hallmark of Nuke Performance products, this tank is designed and manufactured to handle extreme amounts of power. Designed to stand up to the destructive properties of alcohol fuels, including methanol and ethanol. For use on turbo-charged, super-charged and naturally aspirated engine applications. Delivered with stainless-steel mounting plate for easy mounting, 3x 3/4 AN8 fittings and 1x 7/8 AN10 fitting for all the top cover connections. Any 3/4 AN6-AN10 or a 7/8 NPT AN12 fitting can be used if desired. No fuel pumps are included. This fuel surge tank is compatibly with Walbro GST 450 pumps. It can also be used with any 39mm fuel pump such as DW200, DW300, AEM 340L etc. with use of included internal bracket for 39mm pumps.
