INSTALL DAY 1
After laying all the parts out and getting everything we needed ordered ahead of time, we split the project up into two
days of work: replumb the fuel system up to the regulator first, then spend the next day bolting down the new Terminator Stealth throttle-body and running its wiring. Dale’s original setup used a 10-gallon fuel cell to feed a Holley Black pump, a carb-friendly 14-psi, 140-gph unit that strained fuel clean through a Series 140 Mallory Comp-Filter.
We removed the pump, filter, and associated feed lines from the tank, but left the existing -8 feed line to the regulator. From here, we also ran our -8 return line parallel to the feed and simply plumbed it into one of the top ports of our fuel cell with a bulkhead adapter fitting, using a 1-foot length of fuel line to reintroduce fuel at the bottom of the tank. It’s important to plumb your internal return to the bottom of the fuel cell, as creating any kind of waterfall effect breeds cavitation problems from the aeration of fuel. This is a big cause of pump failure or other starvation issues, so take the time to do it right.
Ultimately, this routing is unique to each project, but there are a few best practices to keep in mind. The most direct path is not always the best, so be sure to avoid high-heat areas and be mindful of suspension movement. Most importantly, be sure to place the pump level to or just below the lowest point of
[ This vacuum port lowers fuel pressure at idle to give the injectors finer control while preemptively bumping pressure when vacuum drops at wide open. Set your 43 psi at the regulator with this line disconnected.
[ Don’t forget to clean your braided hose after trimming to ensure debris stays out of the fuel system.
