How to replace a fuel pump for a 98 blazer

[four42]

Does anyone know a good way to get at the fuel pump in a 98 chevy blazer without dropping the tank? Is this possible or do I have to drain and drop the tank. Thanks in advance guys!

Welcome to your first post on AF.
Like BlazerLT said drop it.
The only other way would to pull the body off the frame.

You could remove the carpet from the cargo area, and use something like a Dremel tool to cut a big hole in the floor pan to get at it.

Then you'll never be able to carry heavy stuff, you floor will rust out,
and you'll be able to convert the truck to a drop-top bed-less pick-up.

(I've removed my tank 4 times in the last 1.5 years. It's not that bad really,especially if you're younger than 50)

If you have basic mechanical skills, basic tools (wrenches, sockets screwdrivers etc.) a floor jack helps, and a few blocks of wood, dropping the tank is actually pretty easy, even if you are over 50.

I had the tank out of my 93 and on the ground in less than 1 hour, the old pump out, the new pump installed, and the truck running in 2 1/2 hours.

If you decide to do this job yourself, post back and we can give you a bunch of tips. Do a search on this subject.

I cut a 2'X2' hole in in the bed but I did have to cut a cross member to lift the pump out. I only cut three sides and then covered it back up with some heavy sheet metal with some self tapping screws. Make sure you are over far enough to disconnect your fuel lines. I used a Black and Decker NaviGator with a hacksaw blade and it went through that soft metal like a hot knife through butter. (Like it was made to be removed) You can drop it if you like but this was much easier for me and the next time won't be so bad. BTW if you choose this method... you will need a TX50 Torx bit to remove the cargo tie down shackles, this will be the hardest part of the job, they don't want to come out.

So you cut a structural cross member and patched it with sheet metal and screws?

I wouldn't be bragging about that. You just weakened your frame.

BTW, the bed lift easily off, it is the Blazers that have to drop them.

Sorry Brother but I have to disagree. Why would you want to mutilate your truck and structurally weaken it when it is a relatively easy job to drop the tank? As I stated earlier, I dropped the tank in my '93 in less than 1 hour. How long did it take you to butcher your truck?

If you have the tools and ability to cut through the truck bed and a cross member, you could have just as easily dropped the tank.

I wasn't bragging I was just let him know it can be done. It wasn't a frame cross member just a body one and the sheet metal was just as heavy as the cross member. If you read my signature, I have a blazer not a truck. Plus the hardware that held the plastic cover under the tank looked so rusted I would have been drilling and tapping new bolt holes all the way around it.

Oh well thanks for all these interesting and different ways of getting to the fuel pump. I am going to hold out a little bit on mine because it's my fuel gauge not working so as long I keep it full and watch the mileage I will be OK I hope because I think I have a buyer for it if not a pump will go in my '99.
