3SX Custom Fuel Kits - COMPLETE - BulkHead Sending Unit w/ Aeromotive Stealth Fuel Pump FueLab FPR Filter Lines Fittings Rails

3SX Custom Fuel Kits with 3SX Custom Sending Unit
Complete Kits - Pump + Bulkhead / Filter / FPR / Lines

After 2 years in development we have finally released our 3SX Fuel Pump Sending Units! These units define versatility in your fuel system - from STOCK to 1000+ hp! These kits include custom aluminum bulkheads that are basically the LAST sending unit you'll ever buy! They are set up with AN10 ports for feed and AN8 ports for return - meaning they can be adapted down to serve as a stock replacement unit on a stock SOHC or adapted to run however much fuel and power you are going for! The wiring is properly insulated and "putty'd" in place ensuring a safe seal for the electrical connections - no "nuts-n-nylon-washers" here! The hanger bracket accommodates all of the "smaller" pumps from Walbro, Aeromotive, and AEM. Or remove the bracket and the giant Fuelab Prodigy pumps directly attach to the 3SX Sending Unit allowing for up to their 1800hp rated 722 lph / 190 gph 42402 series pump!

These particular kits are designed for cars running up to about 600 AWHP as they are all built around the Aeromotive Stealth 340 lph fuel pump. A single Stealth 340 pump has been dyno tuned to nearly 600 AWHP on our own in-house dyno!

All of these sending unit bulkhead kits INCLUDE a new gasket/seal for where the sending unit mounts to the tank. The fuel gauge level/bobber assembly is NOT included.

These kit options are "complete" kits in that they replace the factory sending unit and pump assembly with our custom sending unit and an Aeromotive Stealth 340 pump. All kits include a FueLab filter with the 6-micron fiberglass element inside - good for ANY fuel you run from pump gas to e85 to leaded 116 fuels available at tracks. All kits include a FueLab adjustable pressure regulator. The variations are in the fuel rails and delivery and return options.

Installation Notes

1) You will have to transfer your original gauge sender and bobber from your old sending unit to this one. It's only 2 screws.

2) You will also have to wire this unit into your factory system. Instructions are included.

3) Disconnecting the factory fuel sending line can be a challenge. This hose can often get corroded or damaged from trying to remove it to either drop the fuel tank or remove the fuel sending unit.  It is recommended that you disconnect this line FIRST from the long line running up under the vehicle rather than at sending unit - the line's ends are not swivels and can damage the sending unit if you try to disconnect it there first. You can see this line from under the car near between the tank and rear subframe assembly as pictured here.

4) You may need to modify the fuel sending unit cover plate a little to allow for clearance of the fittings. Alternately, you could just space it up as it is not a "sealed" cover.

5) A new Fuel Pump Sending Unit gasket/seal IS included!
