1973-1974 X-Body LS EFI Fuel Tank Kit for Nova/Ventura/Apollo/Omega
Outfitting a 1973-1974 X Body for an LS powerplant often reveals fuel pressure gaps during cornering and hard acceleration; the 1973-1974 Nova EFI Fuel Tank Kit with 255 LPH Pump directly addresses these issues by placing a Walbro module inside a corrosion resistant steel tank. Designed to slot into Chevy Nova Pontiac Ventura Buick Apollo or Oldsmobile Omega frames without clearance conflicts, it draws cooler fuel from beneath the liquid surface to reduce vapor lock and cavitation. Every seal strap and bracket ships in a single kit so installers can complete the retrofit without sourcing additional hardware. Manufactured in the United States and finished in durable powder coat, this assembly stands up to years of road and track use.
In Tank Walbro Pump Placement for Stable LS Fuel Pressure
Positioning the Walbro 255 LPH pump inside the fuel reservoir allows the module to draw cooler fluid from below the surface where temperatures remain stable. By avoiding surface vapors, this in tank arrangement reduces the risk of vapor lock and cavitation when accelerating or taking sharp turns. The pump's rated capacity supports engines up to 550 horsepower so fuel flow remains consistent across the rpm range and under heavy load. Cooler supply also lowers thermal stress on the pump module, enhancing its lifespan and preserving steady injector response during spirited driving sessions.
Powder Coated Steel Reservoir Ensuring Long Term Durability
The fuel tank is crafted from heavy gauge steel and protected by a uniform powder coated finish that resists corrosion, moisture and road contaminants. This protective barrier prevents rust from forming on the inner and outer surfaces so debris is kept out of the fuel system and component wear is minimized. Every tank receives strict coating adhesion testing and weld integrity inspections to guarantee a lasting finish. Together these measures ensure that the reservoir stands up to regular road use and track conditions without compromising fuel purity.
Seamless Chassis Fit for 1973 Through 1974 X Body Frames
Engineered to match the contours of the Nova, Ventura, Apollo and Omega frames, the tank installs without trimming or modifying the original mounts. Its precise shape avoids contact with suspension links, chassis brackets or parking brake hardware, delivering a plug and play retrofit experience. Installation guides walk technicians through removal of the old tank, alignment of new straps and routing of lines in a methodical order. This careful approach reduces the chances of clearance issues and streamlines the entire conversion process.
Complete Retrofit Package for Simplified LS Conversion
Everything needed for an LS swap arrives in one box, including the pump, internal module, sending unit, filler neck, vent filter, mounting straps, gaskets and hardware set. Detailed instructions break down each step from old tank removal to level sender wiring so installers follow a logical progression and avoid guesswork. By consolidating all parts, the kit eliminates time wasted sourcing separate components and cuts overall labor hours. As a result both professional shops and home builders can complete the upgrade efficiently with confidence in every connection.
