Racetronix introduces its new E85-compatible billet aluminum filter assemblies.

FEATURES:

• ORB ports for full flow and reliable seal
• 10-micron SS magnetic filter elements
• E85 compatible
• Flow direction indicator
• Low restriction / high-flow capability
• Black amodized aluminum

Racetronix filter assemblies are an affordable, reliable and visually attractive way to protect your fuel system components from contaminants and potential engine damage. Unlike many aftermarket fuel filters which only offer 30, 60 or 100-micron filtering, this Racetronix unit filters particles down to 10-microns. This specification is comparable to factory filters which are designed to properly protect fuel injectors, check-valves, jet-pumps and other sensitive components found in late-model fuel injection systems. A magnetic pick-up is integrated into the filter to trap small metallic particles for added protection. ORB adapter fittings, mounting brackets and replacement elements are available. Optional 30, 60 and 100-micron SS magnetic filter elements are available as pre-filters to protect fuel pumps from fuel tank contaminants.

Racetronix introduces another innovative product with its new QDF-series EFI fuel system hose ends.

FEATURES:

• Male / female 5/16″  and 3/8″ versions
• 90° versions available
• Full-flow crescent-lock versions available
• E85-compatible
• Replacement locks available
• Radius FF crescent-lock versions available for mechanically harsh environments
• Viton™ o-rings are used for enhanced reliability with all types of fuel
• Female QDF is sized to GM fuel modules for proper fitment
• Extended male QDF ends allow proper fitment of release tools
• Black anodized aluminum

Racetronix QDF reusable aluminum Teflon™ hose fittings (ends) eliminate the need for AN / Quick Disconnect adapters normally required in all late-model GM fuel system upgrades when interfacing with factory components. This reduces cost, bulk and another connection. Maintaining Quick Disconnect fittings in a fuel system reduces assembly time and the possibility of leaks with over-tightened (damaged) AN fittings. Please view our new quality line of QDF fittings at a price which is sure to make you smile.

Racetronix introduces its new QDA-series EFI fuel system adapters.

FEATURES:

• 5/16″ and 3/8″ QDA male / female versions
• -6AN and -8AN Male connections
• 90° versions available
• Full-flow crescent-lock versions available
• Extended male QD ends allow proper fitment of release tools
• E85-compatible
• Black anodized aluminum

Racetronix QDA adapters have been specially designed to address some key issues with other brands currently on the market.

• Female QDA is sized to GM fuel modules for proper fitment
• Male QDA have been lengthened to allow release tools to fit properly
• All combinations of QD male / female 5/16″/ 3/8″ to -6AN / -8AN male (JIC 37°) available
• 90° versions available
• Viton™ o-rings are used for enhanced reliability with all types of fuel
• Machining radius altered for improved strength
• Replacement locks available
• Radius FF crescent-lock versions available for mechanically harsh environments

Racetronix listens and delivers… Many customers have noted that there is a wide variation in quality and fitment when it comes to QD fuel adapters. The first problem is that the mating female QD ends are too small to properly fit current-production GM fuel modules. A second problem is that the male QD ends are too short which does not allow for most common release tools to fit between the adapter and the factory female mate. A third problem is that other manufacturers do not offer every combination of QD to ‘AN’ size they may wish to use. Racetronix has addressed all these issues and more with our new quality line of QDA adapters at a price which is sure to make you smile.

PLASTIC FUEL LINES AND STATIC ELECTRICITY

We all agree that fuel and static electricity can be pretty scary. Static electricity is a kind of electric charge that stays in one place- it is static after all. It is the opposite of current electricity which moves from one place to another along a defined path in a circuit.

Static generally builds up when insulators or insulated conductors are rubbed. In order to get rid of static electricity, we have to turn it into current electricity by creating a circuit. That’s what happens during a lightning strike: so much electric charge builds up in a cloud that the air between the cloud and the ground no longer acts as an insulator. And while anyone playing the best round of golf in their life probably won’t admit this, lightning can be pretty scary. So can static discharges in automotive applications. A spark near something explosive and you have a fireball on your hands. We all know the damaging and costly effects of handling delicate electronics after walking through carpet. This is where anti-static products such as conductive hose are required as explained below.

There are two ways we can prevent static build up in a hose: by physical methods or by chemical means. For hoses, this can mean a highly conductive wire is run through them, or, more commonly, through the addition of additives to the tube liner that helps conduct and dissipate static charge. The latter is the approach Racetronix takes with its TFT1170-series Teflon™ hose.

It is important to know why static is particularly problematic with plastics such as Teflon. The conductivity of Teflon is exponentially lower than silicone and even rubber and this is why we don’t see the same anti-static emphasis on silicone and rubber hoses. The antistatic hose offered by Racetronix is essential in applications where media passing through the hose has a low conductance.  Especially problematic are fuels, solvents and Freon. It’s important to note that anti-static liners not only prevent things from going “BOOM!”, but also help extend the life of a hose. In applications using fluids with low conductivity and high velocity, a static charge is quickly build up in a non-conductive hose. This charge then tries to “move” to ground by arcing from the inside liner out to the wire braid. This leads to tiny pinholes in general purpose Teflon hose liners. Late-model factory fuel systems use a combination of conductive plastics and grounding wires in the tank and pump modules to dissipate static electricity. Automotive performance applications can greatly benefit from the use of conductive anti-static liners. The marginally higher hose cost is quickly offset by longer life and improved safety.

In conclusion, when choosing a hose for a new application it is important to consider not only the flow and chemical compatibility of potential hoses, but also the electrical properties. With high flow, low conductivity fluids, please consider Racetronix TFT1170-series conductive lined Teflon braided hoses.
