FASS Suction Tube Kit
P/N# STK-1003.

FASS Fuel Systems is proud to announce the newest addition to its product line. The STK-1003 5/8" Suction Tube Kit addresses many requests to deliver fuel from within the factory sending unit. As you can see in the photo, the 5/8" convoluted tubing connects to the very popular Bulk Head Fitting, which mounts securely to the fuel tank. Unlike other similar products, this will eliminate the possibility of cracking the factory sending unit, along with being able to receive return fuel. Once the fuel module is cracked, fuel can leak from the tank, making it necessary for the fuel module to be replaced. This makes the STK-1003 the best choice in fuel delivery through safe and simple installation. The STK-1003 comes with all necessary hardware from the bulk head fitting to the suction tube in the basket. The STK-1003 family is recommended for pumps up to150gph. FASS will soon be introducing the revolutionary STK-1004 family for fuel flow demands exceeding 250gph!!


Prevents 1/4 Tank Fuel Starvation
The stock OE fuel tank location in pickup trucks is generally along the inside of the drivers side frame rail. With space between the frame rail and drive shaft limited, the fuel tank must be narrow to fit and have clearance away from the drive shaft. Consequently, to contain the volume of fuel required, the fuel tank must be quite long. With vehicle acceleration and/or deceleration waves develop which, with a low fuel level, can cause a fuel suction tube to suck air. To overcome this problem, the vehicle manufacturers incorporate the use of a fuel module with a collection basket.

When the fuel level is low, the collection basket catches fuel as it flows back and forth. Containing fuel in the basket ensures that the engine always has a fuel supply. However, once the fuel level drops below the top of the collection basket the high flow of a High Performance Fuel System will drain fuel more quickly than it enters. This will eventually empty the basket and starve the engine of fuel. Additionally, the suction lines of the stock collection basket are too small to handle the higher flows without cavitation. To make matters even worse, some pick up truck manufacturers have chosen to locate the lift pump in the fuel tank which would block the flow and prohibit the use of the stock suction tube as it is.

This upgrade kit for the stock OE fuel module overcomes the issues above. With this fuel module modification, a high flow after market fuel system can draw directly from the fuel module without problems. The Fuel Module Upgrade Kit has all of the components necessary to convert the stock fuel module into a high flow system.
