New factory replacement fuel line o-ring kit. This kit covers both fuels lines that connect at the driver side front frame rail. The feed line goes to the fuel rail and the smaller line goes to the regulator. Each kit includes (4) seals. The (2) smaller o-rings are used on return lines and the (2) larger o-rings are used on feed lines.
Our o-rings are indentical in diameter and thickness for a perfect fit.
Whenever removing your fuel rail, fuel pressure regulator, or fuel lines (for service or replacement), it is always recommended to replace these seals.
Over long periods of time, mileage and heat break down the material which can cause a major leak. If you don't know how old your seals are, it's a great idea to change them BEFORE they leak.
NOTE: Always lubricate generously prior to installation to avoid o-ring failures.
Fits all 1978-1987 Turbo Regal applications.
