[Tigers] Fuel Filters

[steve wick]

I've seem hard metal lines crack as well, but only when one of the devices
they connect has significant vibration and they aren't mounted to the same
platform. The fuel pump doesn't move that much, if at all. I've seen rubber
lines crack more often, because of age. Ford used to run hard lines from the
fuel pump (mechanical) to the carb and only used rubber at joints between
major assemblies, such as the tank and the input to the fuel pump (due to the
engine vibrating differently than the car. The new issue we have to deal with
is the ethanol in the fuel that eats rubber fuel lines. I'm replacing the
rubber lines to my fuel pump right now with hard lines, because they've gotten
hard and collapsed, cutting off the fuel flow. If you feel the need to use
something flexible, use the new plastics that are ethanol safe. Just my .02
worth.
