How to mount fuel pumps within the Walbro GST Fuel Surge Tank.
The fuel surge tanks from Nuke Performance come delivered with everything you need to easily install all common fuel pumps but we recommend adding one of Nuke Performance's fuel pump mounting kits for optimal functionality and serviceability. For internal fuel pumps, you need a single fuel pump kit for each fuel pump, so if you run two fuel pumps you need two single kits. All fuel pumps are securely mounted in all conditions thanks to the internal Aluminium billet fuel pump bracket.
How does a fuel surge tank work and how does it flow?
Your stock fuel pump or aftermarket lift fuel pump functions as a pickup fuel pump that fills the surge tank and ensures that the high pressure fuel pumps within the over-sized surge tank. The fuel surge tank always ensures you have enough fuel to maximise fuel flow and minimise the risk of starvation that can seriously harm your engine.
