You will need to upgrade the fuel system on your truck to support the EFI high-pressure fuel delivery. One of the challenges you’re going to run into is that the fuel tank is behind the driver seat in the cab. Keeping that thing sealed and vapor-free for the passengers can be tough. An aftermarket fuel tank may be a better option. Ecklers Classic Chevy Truck parts offer a really nice 19-gallon aluminum tank (PN 129317) that mounts between the framerails behind the rear axle. You have two options for fill locations, through the bed or putting a door and fuel fill through the fender. This tank is fully baffled. Another source we’ve used in the past is Rock Valley Tanks, which didn’t list a tank for your application, but we can’t believe the company doesn’t make one that will work. One of the beauties of the Rock Valley tanks is that you can order it complete with whichever intake pump you need to feed any engine.

Out to Pasture

I am sure you made a simple typing error in your answer to the Engine Dyno Information question in the Apr. ’12 issue when you stated, “The formula for horsepower is: Torque multiplied by 5,252 divided by engine speed equals horsepower.” That wouldn’t work. As you know the formula is torque times engine speed divided by 5,252 equals horsepower.

I enjoy your informative column. Keep up the great work.

Boy, did I step in it this time! Thanks for bringing this to our attention. Formulas like displacement, swept volume, cc to cid, and horsepower are all up in the noggin. We can’t believe we screwed this one up! As one of our good friends, motorsports journalist Rick Voegelin, once said, “Doctors bury their mistakes, writers publish them.” Sorry for any confusion out there. CHP
