ok i have a 85 s10 2.8l carb. and i am goin to be changing out the gas tank on it. i have a lmc truck book and a 20gal. tank will be about 100 bucks before shipping. i also looked on jw and they have one for about 155 that is plastic. which one should i go with? also im wanting to put a electric fuel pump on it. what would i have to do to get that on there if it's even possible. also how hard is it to hook up a after market gas guage? also what all do i need to buy for this. like do i need to replace the tank straps? you know stuff like that. any help would be great. thanks guys.
