    The two tanks are linked at the selector valve, one should not drain the other.

    Replacement is straight forward, unhook the fill hose, unbolt the support straps and lower the tank. The fuel pump and sending unit are held by a retainer ring, use a flat punch to tap it counter clockwise to release. Do the empty tank first, then siphon as much fuel out of the other, or run it dry to replace it.

    Try American Designers for your tanks, they are much cheaper than the dealer and you'll have them in about 3 days. A hint: they give a considerable discount to commercial operations. Thay also have the mounting straps which are usually shot too, plus new retainer rings and gaskets for the pump.

    George,

    Just had to drain my rear gas tank so heres a suggestion. Get one of those three dollar Kerosene pumps and a section of clear vinyl hose to fit over it to reach into the bottom of the tank. You pump that little nozzle half a dozen times and keep your gas can below the level of the tank and youll be drained in no time. Worked great for me, now i just gotta get the tank fixed.

    I had to replace a few Ford tanks last year.. WHy.. WHy cant they make polyethelene replacement tanks for these things... The steel doesnot seem to hold up for our application... Lost the rear tank in a 95 F250 and the Front and Rear in an 85 150 .. Not fun... They were pretty stratigt forward to replace,, Just watch those electrical connections on top of the tank , I broke one, and now dont know how much fuel is in that tank..LOL... Got to get an new connector one of these days..

    When using a punch or drift to remove the sending unit lock ring,make sure it is made of BRASS.DON'T use steel punches as they may create a spark,and we all know sparks and fuel don't mix.If the ring is really stubborn just bend and pry it off,and get a new one,as they are dirt cheap.

    Poly Replacement Fuel Tanks

    George when ever possible replace with with a "poly" tank. Then you wouldn't be doing the job over in a few years! E-mail me if you would like replacement tank info. :rolleyes: John

    I've replaced the rear tank in every Ford pickup I've ever owned! If Ford used plastic tanks the Crown Victoria problem would not exist. The 91-96 Caprice used a plastic tank. We never had to replace any in the NYPD RMPs. We dragged a burned 94 Caprice out of Ground Zero. The car was burnt to a crisp but the plastic tank was intact! I wouldn't believe it if I didn't see it.

    I've replaced my '93 150 tanks. Its not very hard at all. I got a replacement steel tank at autozone for $100 and then sprayed it with undercoating to help it last longer. JCWHITNEY has poly tanks for about $130

    Smokey, thanks for the reply. I've become proficient at rear tank replacement. I'm going to look into the poly tank because the rear tank is leaking in my 93 F150.
