Constructed from low-permeation rubber that tolerates ethanol-blended gasoline, the kit combines a hand-priming bulb, directional flow marking, and snap-on connectors so you can install or remove the hose quickly without special tools. Reinforced metal springs at the connection points help protect the ends from kinking and premature wear while minimizing seepage.\u003c\/p\u003e\n\n\u003ch3\u003eHow long is the hose and will it fit my boat or RV?\u003c\/h3\u003e\n\u003cp\u003eThe Saipe assembly measures 6.89 feet (2.1 meters) and uses a 5\/16\" (8 mm) inner diameter with a 7\/16\" (12 mm) outer diameter, a common size for many outboards and portable tanks.
