Over the years, we’ve fielded a lot of questions…

Given the nature of our products, most of the questions we’ve received have been specific to the application, but on this page, we’ve presented the most frequently asked ones with common applicability, which we hope can give you a sense of how we do things here, and the kind & caliber of the products you’re buying.

You can browse the list by category, and if you don’t find an answer to your question – or have a specific one, technical or otherwise, about whether our products would be a good fit for your project – feel free to contact us anytime!

General Questions

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.

We use Made In USA or USA-owned wherever possible:

Genuine Texas Instruments and National Semiconductor components are used in our controllers.

The connectors are sealed Delphi GT series connectors, the same parts used in the latest GM cars and trucks.

The potting materials, box, conformal coatings, wire, etc. are all UL-94 rated.

Even our circuit boards are Made in the USA.

How American is that 😉

All of our products are covered by our 1-Year Limited Warranty.

In case of malfunction, your VaporWorx component will be repaired free of charges according to the terms of the warranty.

After the warranty period has expired, repair service is charged based on a minimum and maximum charge rate. (Contact us for current rates).

Compatibility

Currently the VaporWorx controller has been validated to work with the following fuel modules and hat systems:

  • Cadillac CTS-V2 (single and dual)
  • Camaro Gen5/6 LS3 and ZL1 (single and dual)
  • Late model GM Trucks (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)
  • DeatschWerks CTS-V2 direct-fit pumps (custom controller calibration required)
  • AM A1000 (custom controller calibration and bypass fitting required)
  • Bosch ‘041 (custom controller calibration and bypass fitting required)

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.

60A in standard form. Higher power units are available if needed (contact us if that's the case).

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.

Fuel Modules

Yes.

VaporWorx can test fuel modules for PWM compatibility and have flowrate testing performed. Please contact us for more information.

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.

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. We have seen +15% of fuel pump output loss due to the need to drive the suction pumps.

The other factor is that a “450lph pump” will have a different flowrate for each pressure and input voltage change.

A rule of pumping is that the higher the pressure, the lower the flowrate.

The TI450lph pump, F90000267, flows 455lph at 30psi/13.5v.

At 60psi/13.5v, the flowrate is 381lph, a 16% reduction in flowrate.

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.

Yes, depending on the scope of work. Please contact us for more information.
