Hesitation and fuel pump bad?

[cj5]

Hi all I'm back well iv got a couple new questions first off thanks for all the help with the sway bar and now I have a little hesitation when I give it the gas it only for a half a second it almost feels like a miss but just for a min and it not right when I hit the gas it's a half second later and the other question is every once in a while I can here my fuel pump and its getting louder I can't always hear it but I can some times should I be worried? I am leaving on a + day camping trip on the 27th so I would like to know is I need to sweat about the fuel pump or not I don't have extra money so just replacing a 300 dollar pump is not something g I wanna do

What year model?? How many miles? Any maintence history and/or recent MODs?

 

Pre-2004 trucks have a servicable fuel filter & at $15.00 it's a cheep start. These should be getting replaced yearly on a 12-15K mile driven truck anyways (with todays crappy ethonal).

It's a 2007 and I have done regular oil changes since I've owned it (110k-148k) I'm gonna do plugs next and no it's a completely stock rig and its an ltz if that makes any diff

I recommend AC Delco iridium spark plugs. A can of Sea Foam brand fuel treatment in 1/2 a tank of gas would be great too before your trip.

 

I know you said money was tight, but at least price 2 new AC Delco upper O2 sensors too- If they are the originals. These can help your fuel milage some too.

I'll look those up as soon as I get done with my scout 800 and also I have been having issues with the ac it blinks and won't go on I read up on it and thought the batt was bad cause it will die in like 5 min with the radio on so I just put a new one in and still no go so do I have a leak in my ac system and should I try the recharge kits at AutoZone or something
