The kit performed as advertised. For air horn enthusiasts I would recommend discarding the small diameter hose included and upgrade to a 3/8 inch I.D. reinforced hose capable of handling 225 plus psi. If mounting under the hood take into account the heat, especially during summer, for it will reduce the psi capability slightly. Use the Wolo 804 electric solenoid valve and slightly drill out the intake and exhaust ports. Convert each opening to a 3/8 in. barbed nipple. For the tank, slightly drill out the exhaust port and add the barbed nipple here as well. Double your hose clamps on each connection. This is a little added insurance against air leaks. If this is going on a PVC air horn the reinforced hose previously mentioned, will allow enough air volume to better run your horn(s). Remember, it's volume not so much, pressure that runs your horns. Use this same technique if you are purchasing the Wolo kit with the long extended tank as well. Happy honking !!!
