PTFE Fuel System Kit

Fuel plumbing from scratch, with the chemistry question already answered.

First fuel systems die of decision fatigue before they die of anything else. The Finish Line Factory PTFE Fuel System Kit compresses the decisions: a common setup of basic fittings and PTFE-lined hose, the liner that treats E85, methanol, and long fuel soak as non-events, in 04 AN, 06 AN, 08 AN, 10 AN. Other parts, such as ORB adapters or fuel filters, may be needed to complete the system, but every wetted surface in the box already speaks aggressive fuel.

Benefits

• The core plumbing arrives as one matched, same-size family
• E85 and methanol compatibility is settled before the first cut
• Feed and return logic assembles from parts designed together
• The remaining shopping list shrinks to filters and interface adapters

Features

• Starter kit: common fittings plus PTFE-lined hose
• Sizes: 04 AN, 06 AN, 08 AN, 10 AN
• PTFE liner: suits all fuels including E85 and methanol
• AN fittings throughout for serviceable connections
• Supplement with ORB adapters and fuel filters per your system

The Details

A fuel system is a loop with opinions: tank or cell, feed to the rail, regulation, return, and every interface along the way. The kit standardizes the lines and fittings of that loop in one size family, with PTFE's chemistry closing the fuel-compatibility question permanently; assemble with the PTFE-specific technique the hose ends require, fresh olive per fitting. Size by power and pump, with 6AN feeding most street builds, 8AN the popular headroom pick, and 10AN serving serious flow. Filters, regulators, and rail/ORB interfaces finish the specific system; the kit is deliberately the universal part of the job.
