over the course of the last week i have noticed that my fuel gauge is getting "lazy" and not reading what i feel to be the proper amount of fuel that is in the tank. the truck in question is a 1994 ranger 2wd, extended cab with the 3.0l. the fuel pump and sending unit are less than a year old and only have 6200 miles on them. i did a full restoration on the truck and everything was working fine until i took a trip to flint and noticed my tripometer showed 260 miles (i usually only go 250 before i fill it back up because its on E) and the gas gauge was still showing 1/4 tank. i immediately pulled off at the next gas station and threw $20 in the tank and the gauge climbed back up to 1/2 tank, about where it should be with $20.
i put some lucas fuel injector cleaner into it the next day thinking that if the sending unit was sticking it would lubricate it (unlikely), but nothing changed. i ran the rest of that tank out and filled it back up and the gauge read full ( a little past full, but thats been normal since ive been driving it). ive got 180 miles out of this tank and im showing just under 1/2 tank and i feel it should be closer to a hair over 1/4.
could a failure at the anti slosh module cause the signal to be "frozen" or is it more likely that the sending unit is sending skewed resistance values to the gauge even though its so new? i plan on pulling the bed off in a while (when it gets warmer) so i can to some hands on testing, but i figured id see what the rest of our knowledgeable members thought.
