The Aeroflow Performance submersible in-tank fuel hose is designed for constant contact with any fuel (including alcohol based, E85, race fuels etc.) on the inside and the outside. It's the perfect solution for those that intend to upgrade their OEM fuel pump to aftermarket performance fuel pumps. The corrugated design means it is completely flexible and is constructed from P12 Nylon which has a 250PSI burst strength rating. Each pre made length of hose includes two new stainless steel ear clamps which must be used to install the hose.
