In mechanical fuel injection tuning, the smallest air leak in your testing equipment can lead to a completely false "leak-down" percentage. If your hose is cracked, dry-rotted, or the fittings are compromised, your barrel valve settings will be inaccurate, potentially leading to a lean engine condition or poor throttle response. The Longacre 52-73017 Replacement Hose is the factory-spec solution designed specifically for the Longacre Barrel Valve Setting Tool (52-73016).
This high-quality replacement assembly ensures a 100% airtight seal between your setting gauge and the fuel injection secondary. Constructed from fuel-resistant materials, it is built to withstand the harsh environment of a sprint car or drag racing pit, where exposure to methanol, nitro, and cleaning solvents is common.
Key Features
-
Airtight Calibration Accuracy: Engineered with precision-crimped fittings to ensure zero "system leakage," providing the dead-on data needed for barrel valve percentage settings.
-
Fuel & Chemical Resistant: Manufactured from a specialized compound that resists the "hardening" and cracking caused by constant exposure to racing fuels and shop degreasers.
-
Flexible High-Flow Design: Features a supple, kink-resistant hose that allows for easy maneuvering in the tight confines of a crowded engine bay or injector stacks.
-
OEM Factory Direct Fit: This is the genuine Longacre replacement part, guaranteed to thread perfectly into your existing 52-73016 tool without the need for adapters or Teflon tape.
-
Professional Grade Durability: Designed for the high-frequency use of a professional engine tuner, offering a much longer service life than generic hardware-store tubing.
