For engines that use an EFI type pump with a carburetor, the GFB FX-D LP bypass regulator is the perfect solution for fuel delivery. Dual -8AN inlet ports offer installation flexibility, whilst the two 1/8" NPT gauge ports allow the use of both a mechanical gauge and electronic pressure sensor if required.The FX-D LP features a Teflon valve seat for superior fuel pressure retention after shutdown, leading to easier starting. We also use a double layer reinforced diaphragm and stainless steel valve that offers a burst strength in excess of 500psi!
