Don't think anyone has posted this diagram from "1954 Chevrolet Truck Engineering Features." It shows a straight Road Draft Tube on the '54 engine with single front motor mount. A similar tube is shown in Sect 6, Sheet 1.00 in the "1947-1954 Truck Factory Assembly Manual." Both diagrams show the correct fuel pump with in/out ports angled 20-deg to the block.

My '54 has a bent road draft tube. Not original to the truck - I bought it a few years ago. Not sure what it came off of. The hole in the block for the tube was plugged with a freeze plug and cobbled up California emissions hoses were on the engine. My bent RDT attaches to the correct point on my '54 235 truck block and clears the fuel line from the tank to the pump.
