The Wold Fab Fuel Sump is the perfect fuel sump for your aftermarket fueling needs. With its simple "One Bolt" design It makes mounting easy. All of our Fuel Sumps are CNC Machined out of aircraft grade billet aluminum. The Wold Fab fuel sump offers a drain plug and is designed with O.R.B. fittings. In our opinion O.R.B. fittings (O-ring Boss) work better than many of the other products out there that use pipe threads. Our fuel sumps are sealed with durable BUNA O-rings and will not deteriorate over years of use. In most applications our Fuel sump can be installed in a matter of minutes, using nothing more than a 3" hole saw and an allen wrench.
