Frequently Asked Questions

• Q: Does the Dorman 800-085 fit my 2003 Ford Focus? A: Yes, it matches the FLRQ‑035 part number used on most 2000‑2007 Ford Focus models.
• Q: Can I paint the black coating? A: Absolutely. The coating is paint‑ready; a light‑spray primer followed by automotive paint works well.
• Q: What fuel pressure rating does this connector support? A: It is rated up to 60 psi continuous, which covers virtually all passenger‑car gasoline systems.
• Q: Is a special tool required for installation? A: A 7 mm flare tool is needed to seat the metal flange; no additional specialty tools are mandatory.
• Q: How does the nylon sleeve handle ethanol blends? A: It is compatible with up to 70 % ethanol (E70); higher blends may degrade the nylon over time.
• Q: Will the connector corrode if exposed to road salt? A: The steel core is coated, but prolonged salt exposure can eventually chip the coating, so stainless alternatives are preferred for marine use.
• Q: Is the connector reusable after removal? A: Yes, both the steel core and nylon sleeve can be reused if inspected for damage.
• Q: Does Dorman offer a warranty? A: The connector comes with a limited 1‑year warranty against manufacturing defects.
