Fuel Lines
All of the manufacturers recommended that their fuel pumps be gravity fed, and put a huge emphasis on the importance of large enough lines. For street and light racing use they recommend a -10 line (about 1/2-inch ID) from the tank to the filter and pump assembly, then from the pump to the regulator. Depending on the pump and application, a -8 or larger return line may be needed. Each system is different, so asking your pump manufacturer for specifics is recommended. As a general rule, use high-quality AN fittings with a consistent inside diameter throughout.

We've got some very mixed feedback about which specific lines are compatible with E85. The carburetor manufacturers all told us that any quality steel braided or similar lines have shown no problems running alcohol through them. On the other hand, the manufacturers of the lines themselves were hesitant to put their stamp of approval on it, despite the overwhelming positive feedback. Newer cars are using neoprene or coated metal hard lines for most of their E85 plumbing. Metal lines that don't have an internal coating can be an issue.

Earl's
We've seen Earl's product all over race cars, and for good reason. They have an extensive line of hoses, fittings, and adapters to complete your fuel system. They recommend using their Speed-Flex hose for E85. It's got an extruded Teflon liner with a stainless steel outer braid. It comes in AN sizes -3 through -8, and is even resistant to brake fluid.

DESCRIPTION: PART NO.: PRICE:
Speed-Flex -6 hose n/a $6.51/ft
Speed-Flex -8 hose n/a $7.54/ft

Filters
Since alcohol-based fuels tend to carry more water than gasoline, the filters can't be water-soluble. Paper is more sensitive to exposure to water than other materials, so they should be avoided unless the manufacturer states it is alcohol friendly. Most of the top-shelf filters use a metal or plastic screen to catch debris. Another issue with the filters can be the O-ring style fittings. Some O-rings not designed to work with alcohol will dry out.

Barry Grant
