Frequently Asked Questions:
Does VaporWorx manufacture fuel tanks?
VaporWorx provides the parts and technology to tank builders in order to provide you with a top-quality, OE level of performance fuel tank. Rock Valley Antique Auto Parts is an excellent source for a complete VaporWorx fuel tank and system.
Does VaporWorx have distributors?
VaporWorx does have limited distribution.

Can a VaporWorx PWM system be used on any fuel pump?
Currently the VaporWorx controller has been validated to work with the following fuel modules and hat systems:
Cadillac CTS-V (single and dual)
Camaro Gen5 LS3 and ZL1 (single and dual)
Late model GM Truck when OE vehicle is equipped with OE FSCM
Fore Innovations twin or triple TI 450 LPH ‘267, DW300, AEM 320, Stealth 340.
Aeromotive Stealth 340 single or dual Phantom (drill mod must be performed.)
Later model Ford fuel modules originally equipped with PWM control system.
DeatchWerks CTS-V direct-fit pumps (custom controller calibration required.)
Can a voltage booster be used with a VaporWorx controller?
In most cases, yes. If your controller was purchased prior to June 2015 then the input voltage should be limited to 17.5v. Later versions are rated to 22v. The voltage booster should be used to feed the VaporWorx controller. Note that many boosters lack sufficient power to drive high-power modules. The JMS FuelMax is the best unit we have used. Installation instructions can be found in the documentation section.
Does VaporWorx perform special fuel module modifications?
Yes, depending on the scope of work. Please contact VaporWorx.
Can a VaporWorx PWM fuel pressure based controller be used to slow down the fuel pump in a full-return system?
No. When two pressure regulation systems are operating near the same pressure they may overlap. In that case, which has priority? In order for the VaporWorx controller to work properly the fuel pressure sensor should be the only pressure feedback mechanism, no mechanical return at or below the VaporWorx set pressure.
What is the power rating of the VaporWorx controller?
60A in standard form. Higher power units are available if needed.
Can VaporWorx test fuel modules?
Yes. VaporWorx can test fuel modules for PWM compatibility and have flowrate testing performed. Please contact VaporWorx for more information.
Why would flowrate testing of my fuel module be needed?
If modifications to a fuel module are performed it is highly recommended to have it tested for flowrate output. With this information the known flowrate vs. pressure curve can be used to determine if it is suitable for the engine build.
But the pump that was put in to the new fuel module is rated at 450lph. Isn’t that good enough?
No. Modern fuel modules use some high-pressure fuel to drive the suction/lift pumps. This amount of fuel is unknown, hence flowrate testing is needed to know the true fuel module output. VaporWorx has seen +15% of fuel pump output loss due to the need to drive the suction pumps.
Can a fuel module designed for PWM be used with an external pressure regulator?
Yes, but only if the return is sent back the module reservoir. If not the reservoir will run dry under many circumstances. However, excessive fuel heating due to full power operation may occur.
Where are your parts made?
The good ol’ USA. We use genuine Texas Instruments and National Semiconductor components in our controllers. The connectors are sealed Delphi GT series connectors. The potting materials, box, conformal coatings, etc. are all UL-94 rated. Even our circuit boards are made by a company in Southern California.
