I've read that the fuel level sending unit failure is common on the 2nd gen Frontiers.
The gas gauge in my 2001 is "stuck" just under the full mark. It goes to "E" when the power is turned off, but goes back to just under the full mark when you turn the key on.
Are the first gen sending units prone to failure too? Is it an easy job to replace the sending unit? Should I replace the fuel pump too? Truck has around 139,000 miles on it.
Famous last words: "It looks easy in the 2nd gen sticky..."

Thanks!
John

no, its not that easy to get to. you need to drop the tank or remove the truck bed. its located in the tank and if you do tackle this job, be careful with the connectors on the top of the tank. i've broken a couple on occassion.

if you have a CC short bed drop the tank , even if you pull the bed the sending unit will still be partially under the cab
i recommend getting something like this
- Harbor Freight Tools - Quality Tools at the Lowest Prices
usually take about an hour to drop the tank

i agree with this. the nissan factory pump should outlast the service life of the vehicle as long as you don't let the tank run too dry
