The PressureWorx ZL1 LSA fuel module control system has everything needed to provide a stand-alone, OE-type returnless fuel system that meets the GM LSA crate engine fuel pressure requirements.
This kit is intended to be used with the GM LSA ECM and wiring kit for the LSA engine only. For other applications: BoostWorx Returnless Pulse Width Modulation Kit, ZL1 Fuel Pump Module
When used with the Gen5/6 Camaro ZL1 fuel module the system will provide the needed manifold referenced (MAP sensor based) fuel pressure that cannot be met with traditional return type pressure regulators.
Suggested compatible fuel modules:
ZL1 Gen5: GM Genuine M10081 or MU2101 (with OEM fuel level sensor)
ZL1 Gen6: GM Genuine MU2369 (with fuel level sensor)
The OEM fuel level sensor is not needed for VaporWorx controller function but it may be used. It is a popular option for gauges that have either a 40F-250E ohm range or those with a custom programming option.
When combined with the Gen5 Camaro ZL1 fuel module, a 650hp supercharged fuel pumping system is easily obtained.
This setup has been used in hundreds of applications with good success, easier fitment, and low overall cost.
Though the Gen6 ZL1 fuel module is less expensive, it it typically more difficult to use due to its increased mounting height, vertical fuel line attachment, the need to plug a large vent hole, and the need to plug the small nipple used for remote high pressure fuel pickups.
It is strongly suggested to NOT use an inline filter with with OEM fuel modules except Gen3 Coyote GT500. Final filtering is built in. Some aftermarket fuel filters have a built-in check valve which will cause a heat-soak related overpressure condition that will lock up port type fuel injectors.
