A consistent and reliable fuel supply is essential for a high-performance diesel engine. The FASS STK-1003 Suction Tube Kit (In-Fuel Module) is a precision-engineered upgrade that replaces your truck's factory pickup tube, ensuring your FASS Titanium Series lift pump receives a constant, uninterrupted flow of fuel. Machined from durable 6061 T-6 Billet Aluminum, this suction tube functions as both a suction point and a fuel return port, designed to pull fuel from deep within your factory fuel module. This intelligent design is a direct solution for the common "quarter-tank issue," where a lack of proper fuel delivery can lead to a significant drop in pressure and engine performance. By increasing fuel volume delivery, this kit guarantees your engine receives the fuel it needs, when it needs it.
