This is a complete made-to-measure fuel line kit with filter and fittings for the 1984-1987 Turbo Buicks. This kit replaces all the factory lines, fittings and filter assembly. This kit is designed to be used with the factory fuel rail and factory-fit / location regulator (1).
After testing many filter housings and elements we have found that the Fram-type filter housing fitted with aWix filter element provides superior performance when compared to other filter solutions costing multiples more. The Fram filter housing is compact, easy to install, well built and affordable. The Wix E-85 compatible filter elements are very affordable yet filter down to six microns and have plenty of surface area for long service life and maximum flow. This assembly will provide the best protection from contaminants reaching your injectors while flowing over 700LPH with approximately 1PSI of pressure drop.
The lines in this kit are stainless steel braid over Teflon. The SS braid offers great durability and a conductive path to dissipate static buildup caused by flowing fuel. The Teflon core is compatible with all fuels such as E-85 and oxygenated race fuels where rubber hose is not and will break down and crack over time. Teflon hose has a lower friction coefficient than rubber hose so it will flow better given the same inner diameter. Teflon has very low permeability so it will not allow vapors to escape like rubber hose so you can say goodbye to that constant smell of gas fumes in your garage. After much flow testing we have found that a -8 feed and -6 return line provide more than enough flow capacity to support our dual in-tank fuel systems at flow rates in excess of 740LPH.
Some of the most restrictive parts in the TR fuel system are the factory Saginaw (metric) fittings. While the internally seated o-rings provide a reliable seal, they are very restrictive by design. Off-the-shelf adapter fittings are also very restrictive because they rely on the same sealing mechanism that limits the maximum internal diameter of the fitting. To get around this problem, Racetronix machines metric adapter fittings in-house to fit the TR fuel rail and regulator that allows for maximum flow and a positive seal.
All Racetronix fuel lines are pressure tested for reliability.
1. Racetronix recommends the use of an Accufab regulator only. These regulators have proven to be ultra-reliable, stable and do not bleed down.
2. Fram has tripled the price of their fuel filter assembly this year so Racetronix has substituted a similar assembly to be able to maintain the price of this kit. All new filter housings are pressure / leak tested prior to shipping.
