ALL 4.0T - E85 Flex Fuel Sensor Bypass Module - BOOST ETHANOL FLOW FROM YOUR PRE-EXISTING FLEX FUEL SENSOR INSTALL (SRM, aftermarket)
This E85 Sensor Bypass will give your fuel system the boost that it needs! If you already have a flex fuel sensor installed, or SRM/Aftermarket lines installed then this sensor bypass will improve fuel pressure and flow to each fuel rail resulting in more reliable HP! Simply remove your sensor, install it in the bypass and connect your lines with the provided fittings
Introducing the 40T-Performance E85 Sensor Bypass Module!
Engineered and tested in the USA. This Flex Fuel sensor bypass module is:
Cost Effective - Cheaper and less hassle than piecing together a handful of parts and fittings to create a dual path
Easy to install - very quick assembly - no need to mess with the hassle of assembling fittings or finnicky hose ends.
Clean Install - Attractive, compact, high quality CNC component that can easily be mounted anywhere in the engine bay
Safe! - double o-ring seals on the sensor, 4 bolt housing robustly keeps the module bolted together, safe from the risk of fuel leaks and sensor damage from bending when compared to piecing together a handful of parts and fittings. Avoid the risk of engine fire!
This e85 flex fuel sensor housing will allow you to take full advantage of running e85 fuel without any compromise to fuel flow. It does this by creating a parallel dual path for the fuel and completely eliminating the restriction from the e85 internal sensor components.
The 2 pathways: First path, the straight through and the second path, the parallel "bypass" for the flex fuel sensor allowing it to read the e85 content in the fuel. See photos for more details.
With e85 having lower chemical energy, it will require about 30% more fuel volume to flow through the fuel feed lines to the fuel rails. The motor wants MORE fuel not a more restrictive fuel feed by installing an e85 flex fuel sensor directly in-line on to the stock fuel line. This is especially critical when installing the flex fuel sensor on the feed size of the fuel system.
For anyone skeptical that a flex fuel sensor is not a restriction - see the cross-section of e85 sensor internal parts - yes, this does limit fuel flow significantly, especially when running a tune with higher boost and an increase of fuel compounded with 30% of fuel flow required to run e85. See photos
Sensor Compatibility:
Works with most types of e85 sensors with tube diameter of 9.5mm and end-to-end length of 95mm
This includes the GM 13577429, GM 13577379, Continental, VDO, AEM 30-2200, Innovate 3907
*If you have the longer sensor tube 105mm check out our adapter spacer listing
Installation with SRM e85 line kit or any flex sensor using the clip-on quick fittings:
This bypass module can be installed anywhere in the fuel system but since you already have a pre-existing sensor installed, whether just a sensor, the SRM line kit or any flex sensor install, it would be most conveneint to just swap out the quick connect fittings that clip into the ethanol sensor and install the sensor bypass module in its place. S4vage Performance demonstrates this in the video below. This can easily support 1000HP on full e85 and supporting mods.
Installing this fuel bypass will free up electrical strain from your fuel pump(s), deliver a higher flow of ethanol when its needed the most and allow a much safer and secured ethanol sensor isntallation.
Shown below is an pre-existing line kit with sensor installed with quick connect fittings
Sensor with Quick Connect Fittings vs. Sensor Bypass Module: These quick connect fittings may be a risk of failure depending on quality and age. The Sensor bypass module is a rigid assembly that securley houses the sensor for a leak free installation.
Bypass module retrofit into SRM line kit:
All fittings and hardware necessary to do any of the configurations mentioned are included in the kit. Assembly instructions are included.
