i notice today that some of my vacuum lines are disconnected and i cant find any manual to help replace them ford wants to charge me 80.00 bucks just to tell me wants wrong the problem im having is the sucker wont stay running it ides rough when i do get it running it misses when at idle. and the fuel filter is at the carb. but the one advance auto says i need isnt the right one the one thats on there now looks like the inline filter just smaller with a nut at one end. so what fuel filter do i really need?
