Gentlemen: I have just joined your forum I'm new at this so please bear with me. I have a 93' f150 XLT 2WD 5.0 I'm wondering where is the fuel sending unit located for the front gas tank(dual tanks). My gas gauge just went off on my last filll up. I know I have almost a full tank, but does not register anything at all. Here is the kicker, if I turn the ignition key one click it will start registering some fuel. No gas in the rear tank I don]t use it. Any ideas will appreciat any help. Thank you all!
