Features:
- These high quality EFI check valves will maintain fuel pressure in the lines to decrease/eliminate priming time. This will also help fight pressure fluctuations on the pump itself, especially when used in a multiple fuel pump application such as two pumps in parallel. This will help prolong the life of the pump itself and prevents tuning and pressure issues caused when not using a check valve
- M12 x 1.5mm thread screws straight into the outlet of a 044 fuel pump (or any other external fuel pump using an M12x1.5mm thread) and when fitted gives you a -6AN outlet, making fitment to the rest of your custom fuel system a breeze; Opening housing is secured with an O-ring for a perfect seal
- Compatible with fuels, oil, coolant, air, diesel, methanol, ethanol, E85
