Hi...I picked up a KT K85G2 from an estate sale. The KP500V pumps has a small valve mounted on it with a 2 wire connecter that plugs into the ecu. The previous owner cut the lead off right at the coil so i assume he was not using this feature. I ordered a new one from KT but i was wondering what exactly is it doing because the fuel pump works with it disconnected? im guessing it must fail open for it to be allowing fuel to pas thru it.
thx
