EFI Surge Tank Dual Pump System for Stable Fuel Delivery
When adapting a classic chassis for an LS or LT powerplant, maintaining uninterrupted fuel flow under hard acceleration or tight turns is crucial and the MuscleRods EFI Surge Tank - Dual Pumps answers that challenge directly. Constructed from billet aluminum with an anodized finish, the compact unit clamps to a frame rail or tucks neatly underhood while resisting corrosion in demanding conditions. Featuring twin Walbro 255 lph pumps submerged in a pressurized reservoir and fitted with -6 AN connections plus an integrated wiring pigtail, it wards off fuel starvation during aggressive cornering and rapid throttle inputs. Installation stays clean and efficient so builders can move on to the next stage of their swap without wrestling with plumbing or wiring.
Precision Machined Aluminum Housing
The EFI surge tank is carved from a single billet block to deliver unparalleled rigidity and precision. This approach eliminates weld seams and weak points, ensuring the housing resists flex and vibration that could lead to leaks or misalignment under racing conditions. Tight machining tolerances preserve pump positioning and seal integrity, which is essential for maintaining consistent pressure within the fuel system. Additionally, the solid aluminum construction aids heat dissipation, keeping the pumps cooler during extended track sessions and reducing the risk of thermal overload.
Durable Anodized Surface Treatment
An anodized finish transforms the aluminum housing into a highly corrosion-resistant component capable of withstanding moisture, road chemicals, and salt exposure. The resulting oxide layer not only prevents pitting and oxidation but also enhances surface hardness, protecting mounting points and fittings from wear during repeated maintenance. This protective treatment preserves both form and function over years of use, ensuring the surge tank remains both reliable and visually appealing in varied environmental conditions.
Submerged Pump Configuration for Steady Fuel Supply
By situating two Walbro 255 lph pumps within a pressurized reservoir, the surge tank eliminates the risk of fuel starvation under hard acceleration or lateral g-forces. Submersion keeps the pump inlets flooded at all times, preventing vapor lock and maintaining immediate throttle response when launching or cornering aggressively. The dual-pump setup offers built-in redundancy, so if one unit loses efficiency, the other continues to supply sufficient volume, safeguarding engine performance and longevity.
Versatile Installation and Plumbing Efficiency
Engineers designed the surge tank to clamp directly to a frame rail or tuck neatly under the hood, accommodating tight engine bays without extensive fabrication. Standard -6 AN fittings create leak-proof connections to existing lines, and the integrated wiring pigtail streamlines electrical hookup, minimizing the risk of miswiring. Together, these features reduce installation time and complexity, allowing builders to focus on tuning rather than wrestling with fuel plumbing and harness routing.
