Looking at a used ( 202k)

3.7 v6 powered 4x4 that looks to be decent

I've asked him a few questions about it

Mentioned this ..

"The only issue it has is the fuel tank fills slowly the shop in town says it will be a 500 dollar fix, I have not asked anywhere else but a co-worker says he had his fixed for 300 dollars"

whats this some kind of plugged vent ??


any other problems that these trucks are known for

?
