WITH THE PUMP SIDE COMPLETED, REPELLA SIMPLY INSTALLED THE FUEL LEVEL SENSOR AND BOLTED ON THE FUEL FILL HATCH. fuel-injected system, that's a completely different story." In a 800+ horsepower Trophy Truck engine, the fuel injection system requires constant pressure to operate at maximum performance. According to Tipton, the HydraMat works by introducing surface tension and fluid wicking to continue to draw fuel from the tank or fuel cell, even when part of the HydraMat remains uncovered with fuel. So the HydraMat doesn't even have to fully submersed to prevent fuel starvation. This was put to the test early in the development phase when Holley went to ARCA (Automobile Racing Club of America) and saw immediate successes in fuel delivery, even at 33 degrees of banking at full race speed. In the off-road racing environment, a benefit is the ability to eliminate unwanted fuel stops since the HydraMat can continue to supply all the remaining fuel from the fuel cell, down the last few drops. This is something that Gorsuch said that traditional fuel pickups never did efficiently. "Tiny pores in the media seal off any area of the HydraMat that is not submerged in fuel," said Tipton. This means that fuel can be drawn from even the smallest corner of the mat, if fuel is available in the tank or cell. Holley recommends that end-users select the largest HydraMat possible because of the reservoir function it can provide. Off-road race vehicles often get sideways on course, and low fuel levels used to be a huge concern. The properties of the HydraMat allows fuel to be made available at the pickup even under conditions where fuel is sloshing in the tank. As long as the HydraMat is in contact with fuel, all of it can still be drawn into the engine at a constant pressure. The HydraMat can fit in most fuel cell openings because it can be folded and compressed. Also, the HydraMat works with 069 SCORE JOURNAL
