    Decided to change my fuel pump after my mechanic bro's friend tested my fuel pressure. I was getting ready to drop my fuel tank. I decided to make an access hole to my fuel pump and sending unit instead. I had done this before on my 75 blazer when my sending unit went bad. I plan on either buying a new piece of factory bed and using some self taping screws to cover. Or I am going to buy some hinges and make it so I can open with the hinges. My fuel pump wasn't bad there was a small hole in the rubber line that connects the fuel pump. I went a head and put a new fuel pump and filter. I also enclosed a pic of my 14 ff that I changed a few weeks ago. I plan on swapping in a 4 inch lift next weekend if all goes as planned. :D

    Good idea. It's probably much easier doing it that way, rather than try moving that massive fuel tank around under the truck. Makes you wonder why GM didn't think of that when they built 'em ;)

    I think cause they wanted you to pay the 500-800 dollars in labor for a new fuel punp at the dealer. :doah:

    its actually not that hard, i did a fuel pump and shackle flip in my new blazer a few weeks ago and mine even has the skid plate, every bolt was rusted and it took me twice as long, but i feel bette about not hacking my floor now, although i did think it was a good idea after the first bolt broke on me (and the gas tank strap stuf broke)....

    Nate you have a lot more patience than I do. After looking at the skid plate and the tow package and worrying about the tank falling. I decided to cut the floor. I figure when I have to change my sending unit and fuel pump again. It will be a 20 min deal.:p:

    i took out my tank to install the body lift. it had the tow package and didn't know they had a hole in the frame already. if i was to do it all again i woulda thought it through and asked around. the hardest part was gettin to the lines on the tank and gettin the hoses off. just decided to cut em and replace em.

    Wait, Nate are you saying there is rust on a truck in AZ? I didn't think that was possible, I though only those of us here in UT and the north had to deal with that kind of stuff.:haha: :haha: :haha: :haha:

    I got rid of our 1996 because ours went bad. When I was dropping the tank I used a 8" x 12" 2x12 and brought the tank down. Once it was down I then broke a clip above the tank.. at least that was replaced with the replacement sending unit / pump assembly.... however when I put the tank back in I forgot to use the board... and dented the tank. so then when you were down to 1/16 of a tank and hit the brakes at a light.. all the fuel went forward and the truck was starving for fuel... you had to tap the gas to get the fuel to roll back then it was ok... that was the last straw.. I got rid of the truck cuz I wasnt going to drop that tank again :haha:

    so now there is a 2005 trailblazer ext sitting where that truck used to be.....

    The straps, and skid plate came right off of my truck when I changed the fuel pump, and sender unit.

    But my tank was emty-ish and it only has a 4" lift. It kinda made it perfect to crawl under, and catch the tank.

    Had to do the same thing in my Trans Am for the fuel pump. Been wondering how well it would work for the K5, and it looks a hell of a lot easier than dealing with dropping the tank. What were the measurements to get the hole positioned right above the pump and sending unit? Might have my next to-do on the Blazer right there...

    friends 2000 silverado did the same thing, we unbolted the bed on one side and jacked it up high enough to get to the fuel pump. 1/2 hour job this way. I dont drop tanks anymore, its a pita.

    Well I first had to get my center underneath and I measured about where the fuel pump opening is at. I did the hard part already. All you have to do is open the tailgate and get the width of the bed is approximately 6 ft. The center is 36 inches or 35 1/2 inches. From the lip where the tailgate closes go 14 1/2 inches to get your center mark. And from the center mark go 4 1/2 inches from side to side. And from top to bottom go 4 1/2 inches. Which totals overall 9 inches x 9 inches. You can alway cut a bigger access hole if you like.

    actually, i got this blazer from drsnazzy, its got some good amount of rust on it, didnt actually find more of it until i was driving the other day and my seatbelt came loose, guess what... the panel is completely rusted, and because of the trim piece i didnt see it when i inspected it before i got the blazer... my fault, should have never traded my yellow truck for this rustbucket pos, but hey, it looks great until you lift the carpet and trim panels... haha.. nate

    I got a tailpan we can cut an oversize piece from . Smooth the edges ( or round them over ) , apply some stick on weatherstripping to the bottom . And them use four countersink screws and bezels in the corners just long enough to go through .

    Would keep it flatter than a hasp , hitch pin , and hinges .

    I've got three EFI burbs, and two of the three have the same trap door cut in them. I cut a piece an inch larger on all sides, ran a small bead of silicone around it, and tack welded the corners. Makes it real easy to get into them the next time.
