3SX Custom Fuel Kits - BulkHead Sending Unit with Walbro or Aeromotive Stealth Fuel Pump - Drop-in Stock Replacement

3SX Custom Fuel Pump Bulkhead Sending Unit Assembly
Stock Replacement to Mild Upgrade!
ALL Years & Models 3000GT & Stealth

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!

THIS particular listing is designed for the stock replacement and BPU systems and is nearly a drop-in installation!

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

 

3SX Fuel Kit BH-02

This is your OEM replacement fuel sending unit kit! Coming in over $100 less than a factory sending unit assembly, AND this INCLUDES the Walbro 255 pump (!!!), this kit is perfect for ANY 3000GT/Stealth owner than needs a new sending unit assembly due to rust or corrosion. It includes the bulkhead and hanger, Walbro 255 fuel pump and adapter kit, fittings to adapt to AN6 out, and a stainless braided PTFE fuel hose with our own customer adapter to properly connect to the factory hard feed line running up to the engine. All you have to do is transfer your fuel lever gauge assembly from your old unit to this one and wire it in!

 

3SX Fuel Kit BH-03

Step it up a bit and opt for the Aeromotive Stealth 340 lph pump! It includes the bulkhead and hanger, Stealth 340 fuel pump kit, fittings to adapt to AN6 out, and a stainless braided PTFE fuel hose with our own customer adapter to properly connect to the factory hard feed line running up to the engine.

3SX Fuel Kit BH-04

Next Level! This kit includes the 3SX bulkhead sending unit with the Aeromotive Stealth 340 lph fuel pump and is fitted to mate to a full fuel kit with AN8 on the output and AN6 in the return. It includes the bulkhead and hanger, Stealth 340 fuel pump kit, fittings to adapt to AN8 feed and AN6 return through the bulkhead (just cap the stock return tube on the tank). All you have to do is transfer your fuel lever gauge assembly from your old unit to this one and wire it in!

 

3SX Fuel Kit BH-01

Already have an upgraded fuel pump on your old stock hanger? Then you can get the 3SX sending unit bulkhead without a fuel pump! Includes everything in kit BH-02, except the actual pump kit. This kit is perfect for ANY 3000GT/Stealth owner than needs a new sending unit assembly due to rust or corrosion but already has an upgraded fuel pump. It includes the bulkhead and hanger, fittings to adapt to AN6 out, and a stainless braided PTFE fuel hose with our own custom adapter to properly connect to the factory hard feed line running up to the engine. All you have to do is transfer your fuel lever gauge assembly and fuel pump from your old unit to this one and wire it in!

 

NOTE: All the fuel lines included in these kits are crimped lines and made with stainless braided PTFE fuel line. PTFE is compatible all automotive fuels (gasoline, e85, methanol additives, etc) so these kits will be compatible with whatever system you are building!

 

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 OEM fuel pump sending unit gasket/seal IS included!

 

 

Wiring Harness Plug End
Now that we have sourced various harness plug connectors, we are also INCLUDING the female 3SX 6-pin 2x3 Harness Plug Connector so you can more easily wire your new bulkhead to plug into the stock wiring!

 

Don't Let Your Fuel System Look Like THIS!!!
If your fuel tank and sending unit look like this then you NEED one of these kits!!!
