The Ford V-10 gasoline engine can replace the soon-to-be-required Tier IV diesel engine with an intelligent and economical alternative. The engine meets all horsepower requirements for all water pump options from 30 GPM to 120 GPM and up to 3000 PSI, while offering a compact and relatively light weight installation. When combined with an adequate fuel supply for a full day’s operation, it weighs no more than a comparable diesel. The engine meets all 50 state emission requirements and is almost incredibly quiet when compared to diesel power.
