Boat Gel Coat - Spectrum Color, Pumps and The fuel pump controller communicates with the vehicle's ECU and operates the fuel pump to deliver fuel along fuel lines to the engine on demand. An arrow printed on the side should point toward the engine side of the fuel line. These are installed in the fuel line between the portable tank and the primer bulb. But while the engine is idling, less fuel pressure is required, the engine's vacuum will assist the valve's opening, allowing more fuel to flow back to the tank through the return line. The manual release can be used (pushed in) to open (bypass) the valve in case of a fuel blockage in the valve. I believe I would need to add a longer line and a primer bulb to this tank Mfg # 8M0054600. How do I start a successful handmade business?

Fuel demand valves are required on portable tanks made after a certain date due to tighter regulations by EPA. In order to get the gas to drain, it's best to disconnect the primer bulb. This improves fuel economy, and reduces maintenance and tyre wear, although it increases road wear.
