Pressure Gauge Optional.
Fuel flow improvements begin directly within the fuel pump module. Entirely bypassing the integrated fuel filter housing, fuel is pumped directly out the top hat of the fuel pump module through a PTFE hose and -6AN bulkhead fitting. Returning fuel is brought in through the original output port and plumbed into the venturi jet-pump system by replacing the original in-tank pressure regulator with our billet regulator delete assembly.
As the internal filter housing has been bypassed, its internal filter can optionally be deleted to make room for the Walbro 450 or 520 fuel pumps, and/or increase surge protection volume inside the fuel pump module.
The S1.E plumbing kit is constructed from stainless braided, black PVC coated, PTFE hose with crimped aluminum hose ends. An Aeromotive inline filter and a CJM "no-drill" filter mount is included standard. Hoses in the engine bay are secured to the firewall with included cushion clamps. A billet aluminum fitting is also included to adapt the regulator output hose to the original fuel feed pipe, re-purposing it as the return line.
Options:
Vehicle, Pump Type, Filter Media:
- Select your vehicle type, describe what size hose barb your fuel pump has, and choose your filter media.
- 8mm (5/16"): Stock, Aeromotive 340, AEM 340, DW200/300, Walbro 255
- 10mm (3/8"): Walbro 400/450/520
- Cellulose: Gasoline Compatible (10 micron)
- Microglass: Gasoline & E85 Compatible (10 micron)
- For Twin Pump: Deletes the components used for modifying the stock fuel pump housing. Must be installed to pre-existing return compatible fuel pump module, such as CJM twin pump, or used with CJM Return Fuel Pump Kit.
- 3 feet is sufficient to add some protection to hoses just in close proximity to the exhaust manifold.
- 6 feet will provide additional coverage or can be used for other plumbing or wiring harnesses.

Additional Components:
Billet Fuel Pump Hat: Follow the link to learn more about this highly recommended upgrade. Fuel Pump Upgrade: There is no better time to install a fuel pump upgrade! Be sure to opt for the new strainer, pigtail, and relay kit. Fuel Injectors: Complete the package with a set of fuel injectors. We recommend 1050cc injectors for all boosted VHR applications under 700whp.
Technical Notes:
- To emulate the factory fuel system for use with your existing tune, set the fuel pressure to 52psi and do not connect a vacuum line to the regulator.
- Connect a vacuum/boost reference line to the regulator for a 1:1 constant pressure ratio. Consult your tuner.
Additional Photos:
The 4-way fitting interfaces with the stock fuel rail inlet tube. Fuel feed is sent in through the top, straight into the rail inlet. The rear port feeds the fuel pressure regulator. There is a 1/8 NPT port on the front for the optional fuel pressure gauge.
An Aeromotive filter with 10 micron element is included, allowing the bypass (and optional removal) of the factory filter inside the fuel pump module. A "no-drill" stainless filter mount is included to secure the filter to the underbody using an existing underbody cover bolt. The filter is secured to the bracket with heavy-duty Nylon cable ties (provided but not shown). The appropriate adapters are included to adapt the filter to the plumbing kit.
