I think my gas gauge is struggling to work. Like i filled up like two weeks ago like 20 dollars premium and it said i had a 1/2 tank.... so i drove it for like 2 weeks and then gased up today like 10 dollars and it did that click sound to say its full ya know? the pump handle goes click. lol. anyway i get in the truck and it says 1/2 tank again... im like wtf.. while im driving out to the beach it starts going up to like 3/5 and then goes back to half... and then on my way back to the beach it goes to full.... then it goes back to 1/2 then i look again nearing my house and the guage is full... i havent checked since i got home but i will when i go wash it. Anyone know what the probelm could be? 6in 87' K5 w/ 35" BFG muds. Kn filter What I need: 4.11 gears, Lim Slip Dif, Force2 Catback, rear springs , Throtle body spacer.
