DeatschWerks’ New DW400 Drop-In Fuel Pump Module For GM Trucks

A fuel shortage is a bad situation, especially on a modified vehicle. Without the proper amount of fuel, you will never hit the full potential of your combination. Installing an aftermarket fuel pump comes with its fair share of problems too. The majority of these pumps are universal, and it’s up to the vehicle owner or the shop working on the car to make the new pump fit correctly. Thankfully these days are over for the 1999-09 and 2014-18 GM truck crowd thanks to DeatschWerks (DW).

DeatschWerks now offers a new DW400 pump module kit for the GM/Chevy 1500 trucks. This 415-liters per hour pump module is compatible with all Chevrolet gas v8 trucks from 1999-09 and 2014-18. The DW400 fuel module manages to cover the low-level pickup, filtration, and regulation the stock fuel module does. It also utilizes all if the factory fuel sender functions for a super easy and quick installation.

The 1999-2009 module kits come with return system plumbing including the DWR1000 high flow adjustable regulator, -8AN feed lines, and -6AN return lines. The return systems include everything you need for installation into any truck configuration from short bed single cab to long bed crew cab. DW also includes extra fittings and additional hose is so you can route the lines perfectly. These kits are available with either CPE or PTFE hose.

The CPE kits are easier to install and are compatible with fuels containing up to 85% ethanol content. The PTFE kits feature zero vapor permeability and are compatible with e98 and e100 fuels. The 2014-18 models do not require return plumbing kits due to the direct injection fuel system.

Want to know why the DeatschWerks DW400 Pump Module is such a great product? Here is what happened to us while trying to adapt a universal style fuel pump in a 2000 Chevrolet Silverado recently. Since the factory fuel pump basket is designed for a small pump, we had to modify/hack it up to accept the new pump. This basket was super brittle due to being almost twenty years old and ended up cracking in areas. After about two hours of modifications, we got it all worked out or at least we thought we did. After buttoning everything back up, we fired up the truck, and it idled for about 30 seconds before the factory tube failed. At this point, we were down from 58 psi to just 4. We pulled the factory basket and pump back out of the tank and modified the unit even further to fix the hose. All of this would have been avoided if we could have used the DW400 fuel module.

The DW400 module is a drop-in design, meaning that you don’t have to do any of the things that we mentioned above when doing the installation. In the past, that might have been the only option but not anymore. Now you can save valuable time and not experience the headaches with a do-it-yourself kit. Finally, a fuel high-performance fuel system that offers factory reliability with aftermarket performance.
