Hybrid Racing K-Series Swap Tucked Fuel System Package (92-00 Civic & 94-01 Integra)

Convert the fuel plumbing on a 1992–2000 Civic or 1994–2001 Integra K-swap with this Hybrid Racing tucked fuel-system package.

A complete package makes the return-style plumbing, rail, regulation, and pressure monitoring work together. The piston-style regulator damps pressure fluctuations so the gauge is easier to read and set, while the rail offers flexible feed and gauge locations for the way you want to lay out the engine bay.

Important notes

The tucked route uses a center-feed rail and relocates the regulator beneath the brake booster. It changes the original fuel-filter arrangement; use the intended filtration setup.
