So my dad is feeling guilty about selling me his 1991 S-10 4WD truck with leaky gas tank, but the local mechanic is quoting him $500 to replace the tank, sender and fuel pump. My first reaction was "Hey that guys trying to screw you" but then I wondered if there's any weird thing with the S10 where the pump and senders are not removeable or serviceable seperately??? Anyone dealt with this before? The tanks I've seen, you just unbolt the ring on top....gently remove the guts (sender & pump) and then drop them into the replacement tank......right? My next question will be about the availablity of a poly tank vs. steel. My third question will then be to go post up in the "Parts Wanted" section I bought the whole truck for only $1000, and don't want my dad getting screwed over paying for a bunch of expensive repairs, especially if it can be repaired as easily as I think it can.
