Should be on the climate control center, just opposite of the blower control lever.
Two short levers that move vertically. One for fan control, the other for tank selection.

if it was an add on tank it might be on the floor of the cab, usually right infront of where the seatbelt is bolted.

I'll second the floor, I see them in yards sometime with the switch right under the seat on the driver's side.

FUel tank selector switch / fuel tank selector valve & solenoid

1977/79 Styleside pickups: If the midship & aft axle fuel tanks are factory, they'll be behind doors on the left quarter panel.

1978/79: There's no floor mounted switcher valve if it has factory installed dual fuel tanks.

The valve & solenoid assembly is mounted underneath the truck on the frame: D5TZ9189B / Marked: D5TF-9F271-AA / -AB or D8TF-9F271-AA or D9TF-9F271-AA.

The switch (D5TZ9A050A) that controls the valve and solenoid is mounted in the heater control panel. When activated it switches the tanks and the fuel gauge.

The **** (D4AZ18519A) on the switch is chromed plastic and tends to snap off...it's the same **** that's used on the heater control panel levers.

The switch is still available from Ford: D5TZ9A050A / MSRP: $32.18 / ftepartsguy.com price: $17.38

The valve is still available from Ford: D5TZ9189B / MSRP: $91.17 / ftepartsguy.com price: $65.64 / Note: this valve replaced: D8TZ9189A & D5TZ9189A

btw: Ed (ftepartsguy.com), like most dealers today, has no parts catalogs prior to 1980. So when Ed needs parts for pre 1980's vehicles, guess who he contacts.

Hey 7A020 (or mebbe 3A006!)...I'm not only listing all the part numbers for these parts but the MSRP and YOUR FTE member discount prices.

I also put the parts descriptions in the title in case someone does a search....

All a this will save you the trouble of looking for the part numbers, cuz you yourself told me you don't have the references.

*(*&(&^&& 17080 off!!

Don't get the wrong idea fellow members, cuz this is justa little friendly banter between pals.

The D4AZ18519A **** has been replaced by D8AZ18519A and is still available from Ford.

MSRP: $9.03 / FTEpartsguy.com price: $6.50

Numberdummy,

Can you clarify the fuel tank selector valve locations for a 77 and a 79 F-350 Camper Special (140" wb). Both have factory dual tanks.

The valve on my 79 is mounted on the inside of the drivers side frame rail next to the rear tank.

The valve on my 77 is mounted to the bottom of the cab floor on the outside of the drivers side frame rail.

They both look like factory installs, but the 77's location seems a bit odd.

Thanks.

Illustration: Section 90 / Page 8 of the '73/79 parts catalog shows the 1977 F350 140" C/S valve mounted in that location.
