Hello, I am looking for the part # for a "water trap" located between fuel filter and fuel tank. My mechanic says this water trap regulates line pressure which keeps rpm's uniform... He has called all his old friends and ford contacts in the states and can't find this "water trap"... My 1986 ford ranger came without this water trap and runs sporadic and rough and then cleans up and runs perfect. Feels like rpm's are fluctuating...... Please help me locate this water trap I can provide a picture if you need !??! Thank you, John
