Changed the in tank fuel pump this past weekend. Full of gas of course. Put the front part of the tank on a little ladder and the back part on the jack. I was able to drop it just enough to get everything disconnected and remove the pump and sending unit. Went back on no problems. Don't want to do that again for a LONG time though!!

OK all here is the measurement for future reference. Standing at rear lookin in.

1. Go min 11 inches up from the tailpan lip.
2. The side post at tail on the inside measure from each side
28 inches along the lip then mark at the 11 inch line
3. The top of opening should be a min 8 inches.

I hope this helps!

I have a panel I am going to fix to cover it like a hatch cover with a seal under it. It is on my list of to do.
 
I dunno, the job doesn't seem bad enough to me to be worth cutting a big hole in the floor. But then again, I always have a lift and a tranny jack to use:rolleyes:
 
Mine happened on the trail so I really didn't have a choice. The pump came off of the sending unit. A couple months later my fuel pump went out on the trail, so I already had my handy access panel. Made for a quick and easy fix.
 
Mine died on the Highway with 31 gallons in it! $175.00 tow bill and I said never happen again. GM should of made and access panel to do it any way. I have the access panel from a tail gate I am going to use to make the hatch. A tech article in the making.
 
I would love to see a write up on it. Ive been trying to think of a way to make a hatch.
 
I figure the next time my tank comes down (another 100,000 miles or so) I won't even remember how to remove it.

Not quite sure why a 25 year failure item needs a "quick fix" except for wheelers who can't get to the pump if the truck dies in a bad spot. Good components keep you from having to do the same job 2+ times. But to each their own. I know what I've done on my truck.
 
I just had to do one of these Saturday. Got it done in 1 hour 15 minutes including the time I spent getting the part. Full of gasoline too. Only cut my thumb and saturated on sleeve with gasoline. My buddy comes up the driveway with a lit cig and asks whats up... Good times.

2008 - 1987 = 21 years :( Also not every one has a Nice Garage and a crap load of tools to do things with.:rolleyes: Also in my case I am not healthy enough to do it on my back and alone with a jack and my arms.

SO a lot of you who have GARAGES or nice places to work on you truck with tools up the wazoo need to count your blessings. Some of us don't have it as good as you might. :doah:

:rolleyes:

If you've got the time and tools to cut a hole in the floor to cut corners, you better have a ratchet and a floor jack or your priorities are screwed up. :rolleyes:

Everyone that changes their fuel pump without cutting a hole does so inside a garage? I know the 4 or 5 times I've had my tank down certainly didn't happen inside.
 
Yeah i did mine just like Hubnut cept i used my dad garage.

I'd be scared ****less to cut anything around the gas tank. I'm not gonna blow myself up :dunno:
 
Air chisel at service station. Whatever dude...........unsubscribed.
 
Last time I did mine (hopefully THE last time) I removed one tank strap and put a ratchet strap on, removed the other strap and installed a second ratchet strap. I could then slowly lower the tank to gain access to the pump. lifting it back up was as simple as ratcheting it back up. I've gone thru 3 pumps in 10 years. The first was the original I think. second was an auto zone pump that lasted 3 years, third was a NAPA that lasted about 30 minutes. It actually failed after filling the tank!!! Last is an AC Delco, 5 years and counting.

I have changed a lot of these damn things so Im not sure where your getting "good components" I have used every brand out there and I would not trust any of them for 25 years. The pump in my 97 is currently SCREAMING even after a filter change. Im sick of dropping tanks so im going to cut a hole in the bed. I might add that some are a bit more difficult than others I have not done one on a K5 and it looks to be pretty straight forward. The IFS pickups are a pain in the ass and so are S10 pickups. You have to remove straps and frame hangers and sometimes the drive line.

ANYWAY Im going to cut a hole in my bed and make a access door. This is the second pump I have replaced on this particular truck seams to me about 1 a year and they are delco pumps as they seam(ed) to last longer than most. Parts quality has taken a dump in the last few years I think.
 
If someone wants to cut a hole in the bed, I got no problems with it.

I suspect what he meant was that you don't hear much about cars and trucks needing the fuel pump replaced very often. Even if you reduce the 25 years down to 5 years, I'm not sure it's worth all the work of cutting a hole in the bed for something you have to do every five years. Dropping the gas tank didn't feel like much more effort than changing a tire, maybe a little more effort.

Now, if your pumps are going out sooner than that there's something wrong. Either the tank is filled with 25 year old crud, or the pumps are junk. I've never owned a vehicle that needed the fuel pump changed more than once.

you got that right even though i go a different route. I always get a second person and lift the bed off the truck makes it tons easier. I haven't done it on MY truck but have on my brothers and my stepdads.

My dad even tried it but had problems so i helped him take the bed off. Had it out in like 30 minutes :D

I type this post and i guarantee you within the next week i'm gonna have to change mine :doah:
