Part # HKS-1001

This splitter allows for easy connection if you are utilizing (2) dual FASS Electric Heater Probes

Part # HK-1002

When the fuel temperature drops below 34° Fahrenheit, the thermostatically controlled High Output Fuel Heater Disk will automatically power on. Fuel is then heated by the 300 watt heating element as the fuel is entering the FASS System, preventing gelling of the diesel fuel in the FASS filters. As the FASS continually polishes the fuel it will heat the fuel in the fuel tank, further preventing gelling. Once the fuel reaches optimal temperature the High Output Heater Disk will automatically power off, eliminating the possibility of overheating the diesel fuel.

FASS Suction Tube Kit P/N# STK-1002. The Suction Tube Kit for FASS and AirDog high flow fuel pumps was developed to retrofit the stock fuel pickup basket assembly to eliminate the need for a new pickup tube assembly, or "Draw-Straw", on trucks with in-tank equipped fuel pumps. This kit is not a replacement module, it is an upgrade kit for modifying your existing fuel module. If your 98-01 Dodge 5.9L ISB has had the "In-Tank" fuel pump conversion, then this kit will be required to install your FASS or AirDog system. On all other vehicles, this suction tube kit will prevent "quarter tank fuel starvation" issues, and allow your FASS or AirDog system to flow unrestricted at it's highest potential. This suction tube kit works with all FASS and AirDog complete systems as well as aftermarket high flow fuel pump assemblies such as the FASS HPFP & DDRP pumps and AirDog FRRP & Raptor pumps. This kit may not be required on some vehicles or certain FASS and AirDog systems. If you're unsure, then please call us before ordering.

Installation Manual

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.

• 5/8" Radius Cut - This is like your Mandrel Bends in your High Performance exhaust system. This radius cut not only cuts down the "eddy current" (unwanted flow disruption - swirl) but reduces noise by 2 - 4 decibels!
• 5/8" Suction Tube - Gives a true ½" I.D.!
• Angled Return Port - Directs the returned aerated fuel away from the fuel supply!

Part # HK-1001

A bolt on option for the Titanium Series Fuel Air Separation System, this Electric Heater Kit will begin warming your diesel fuel once the key is in the “ON” position and will automatically shut off once the fuel is at its optimum temperature. This will aid during a cold weather start and prevent fuel from gelling inside your lift pump.

Part # 32283

A replacement element for our FASS Electric Heater (HK-1001). This item is intended for replacement parts only.

FASS Fuel Filter # FF-2003 has been discontinued and replaced with filter # FWS-3003, which utilizes a different thread that is more widely used in the filter industry.

If your FASS already came with the new # FWS-3003 fuel filter, then you already have the new style FASS and no further parts are needed when replacing your filters.

If your FASS originally came with a # FF-2003 or # FF-5712 filter, then you will need to buy a FASS Nipple Adapter # FSN-2001 so that the new filter (# FWS-3003) will fit properly. You will only have to purchase this adapter once since it can be re-used when replacing filters in the future.

Part # PF-3001

Our New Particulate Filter is rated @ 144 microns. The 144 Micron Particulate Filter on the suction side will drastically reduce cavitation, increase flow properties, lower the sound output of the FASS System, and removes larger fuel particulates.

The new PF-3001 MUST bus used in conjunction with the XWS-3002, the new filters cannot be used in combination with the FF-3003/FF-3010 or FS-1001/FS-1020.

When replacing the discontinued filters with the new XWS-3002 and PF-3001, the XWS-3002 will now be placed on the pressure side of the pump and the PF-3001 will be placed on the suction side. PLEASE SEE THE LOCATION DIAGRAM ON THE NEW FILTERS FOR PROPER FILTER PLACEMENT!
