I am new to this forum and I have searched it but I haven't found anyone with this problem. My gas gauge never goes below 3/4. Then sometimes it will just start hopping around like a rabbit and it won't stay put anywhere. It can't be trusted at all. anybody heard of this and know how to fix it

The joys of a floating gauge. It's awesome, go up hill , its one level, go down hill it's another, straight it's another, I love it! Can do 400km and still have 3/4 tank of gas.. he hee..

Hi, my 2000 did the same thing at about 58,000 miles. I replaced the fuel pump assembly and it works like new now. It was real easy to replace. Just took the tank down and pulled the old one out and installed the new one.

Good Luck,
Mike

Yeah that sounds easy. How much was the new one? Where is a good place to get one?

It is called the sending unit and it is not an easy repair.

You have to unhook and drop your tank etc...

Not for the novice.

I am nothing of a novice and I was leaning toward the sending unit. I have replaced them before on other vehicles. I am new to chevys and I am not sure where would be a good and cheap place to pick one up. This board seems to be full of great advice. I like that especially from people working on the same type of rig. thanks

Everyone has to start somewhere, how do you advance, unless you tackle situations beyond your comprehension? You come here as a novice, ask the questions, read the manuals, take heed of the good advice and the silly, find the answers, and pray you don't mix up the fuel line with a brake line...

I agree, you have to start somewhere.

Luckily for Blazer owners, it's impossible to confuse the gas lines with the brake lines (the feed lines are even a different size than the return lines on the fuel pump housing , so this is a rather simple proceedure, it's just an acrobatic time consuming task to get everything apart and put back together correctly)


Search the forum for fuel pump replacement. I have a post from last year floating around that gives instructions on how to do it- it took me 3 tries to get it done properly

Hi, I bought a new AC/Delco assembly on Ebay for about $170. It was pretty staight forward replacing it. Maybe I was just lucky, but, it took me about 2 hours working by myself.


Good luck,
Mike

You start by knowing how to do normal repairs first.

A person that has never replaced a sparkplug shouldn't think he/she can do this and that is all that I am saying.

Replacing a sending unit is no easy 1 hour task even for people with the knowledge and the equipment.

So let's not all make this to be a simple task because it is NOT.

I have the same probelm on my 2000. I was annoyed at first, but decided to use the trip odometer and fill up every 250 miles or so. I think it will be much more ecocnomical to wait until the fuel pump weakens and then replace both while the tank is down. I have had no real problerms using the odomoeter and it forces me to keep track of fuel mileage. Just a thought.

I used to do the same thing with my '97 until my daughter started driving
and would put $5.00 worth of fuel in at a time. It really screwed up the odometer/fill routine, so I had to repair/replace the unit. (Plus the fact that it costs about $50.00 to fill it up now ... the kids don't have that kind of ka-ching)
