You be the judge.
THE OLD SYSTEM
The car came to us without a fuel system for the most part. The factory fuel sending unit had been chopped and a large -10 siphon tube was installed through the top of the sending unit replacing the factory in tank pump. A -6 fitting was also installed through the top for a return line. A setup like this is not a good idea on high g-force application like drag or road racing. The siphon tube is right in the middle of one side of the tank and can easily come uncovered when the fuel sloshes. In addition, the factory return line also siphons fuel from the other side of the tank which in this setup was eliminated. This setup will draw fuel from the right side of the tank only. In addition to the modded sending unit, the factory fuel lines were also removed.
THE NEW SYSTEM
We decided that replacing the factory fuel sending unit with an unmodified one would be the best bet. This would also replace the factory transfer siphon so it would draw from both sides of the tank. We would then use a Walboro 255L in tank pump to feed a custom surge tank we would fabricate. Fuel requirements for this car were going to be high so we opted to do a dual Walboro inline pump setup. So this is what we ended up with.
Let me know what you guys think.
