Hey guys,

Does anyone know of a locking VENTED gas cap that fits a styleside bed? I've tried numerous caps and none seem to fit properly. Right now, I just have the normal one with the tabs that you turned with a hole drilled in it to vent. The venting is important, because the truck has a diesel engine and I'm running the return line through the valve on the top of the tank. If it's not vented, it will create a vacuum and not let ample fuel flow (don't ask how I know). It also needs to be locking, because I'm going to school soon and don't want somebody who's stumbling home from a party who thinks my truck looks good to mess with and dump anything in my tank.

Any information is greatly appreciated. Thanks!

 

What year is your Chevrolet/GMC?

Don't have fuel cap applications for the GM twins, do have them for F100/350's.

1978:

D8TZ-9030-B .. Single Locking Vented Fuel Cap-includes 2 keys (Motorcraft FC-805-2) / Obsolete ~ 94 available NOS

D8TZ-9030-E .. Locking Vented Fuel Cap KIT-includes 2 caps & 4 keys (Motorcraft FC-806-2) / Obsolete ~ 3 available NOS

 

Thanks Bill, excuse my use of the lowly Chevy term. My FORD is a 79, so I would think that D8TZ-9030-B will work (it's just a single tank). Any idea where I could get one though? I'm currently searching obsolete Ford parts sites with the part number.

 

NOS PARTS LTD in Waxahachie TX has 1 = 972-937-2201.

CARPENTER NOS OBSOLETE PARTS in Concord NC has 93 = 800-476-9653.

 

Are there any aftermarket vented locking caps out there?

 

Napa, orielly, auto zone all carry them.

 

Yes they do, but for some reason the ones they have do not fit quite right.
