BEFORE Trying to pump gas into a filler neck that runs uphill to the fuel tank usually results in wet shoes and a few gallons of expensive gas on the ground. Tree Huggers are going to freak when they see this.
Smooth sheetmetal looks great and every truck could use a good shave job. One of the most often deleted items from a custom truck is the factory fuel filler location. It's common to shave the hole shut and then simply stuff the stock fuel filler neck into the inner fenderwell because it's a convenient spot. The problem with doing so, is that the odd angle of the filler neck usually ends up making it hard to actually fill up the gas tank. Our '73 Chevy C10 is a good example of this. Since losing both gas doors in the bedsides, we now pour more fuel onto the ground than we get into the tank during trips to the gas station.
AFTER Relocating the filler neck to a higher location, in this case it's the wheel tub inside of the bed, gives us a downhill facing neck to pour the fuel into. Gravity is now our friend when at the gas pump.
The solution is a pretty logical one, but it's not always easy to execute. We decided to move our filler necks so that they are positioned inside the bed, with an opening at the front of each wheel well. This required a small amount of re-plumbing and modification of each filler neck, as well as putting holes inside of the bed. Lucas Fab in Huntington Beach, California, made the swap happen with ease and showed us a few cool tricks to making the job look professional and functional.
