I have gotten word my trucks batteries I installed back in 2007 have likely bought it from sitting for the last 8 or 9 months. It could be time for optima deep cycle batteries.

Problem!
Although I'm hovering between 66.5 and 67.5 mpg and hardly use the alternator in daylight, I wonder if the battery mod is damaging the fuel system. Three or four times I have run the voltage down to under 12. Most of the time the voltage is between 12.1 and 12.7. Now I seem to have fuel flow problems. The car hesitates and testing suggests the hesitancy is not not dependent on battery voltage, bump-start fuel pressure loss, throttle position, load, engine temp, or engine speed. I know the fuel pump is electrical. Have I damaged my fuel pump with my weird alternator optional set-up?
