Yes. Unburned fuel from too much air. The air from the starved flame prolongs the burn, and fires the next intake stroke, causing a backfire. In a normal combustion process the flame front puts out the fire, by using all the air. A rich condition runs out of air, and overly lean has too much air, and not enough fuel. What comes out the tailpipe looks, and smells the same. With that distributor, and pump, thus truck never ran this smooth for me.
Hi. What did you use to cut the access hole? I've had my 99 Tahoe for many years. It's on the 3rd pump. It went out last night. With a full tank of course. I'm considering this even though it has no rust. But it is sitting out in the snow and rain. Thanks a ton!
I have a 98 K2500HD and the fuel pump quit when I went to move it to plow snow in December. I cut a hole in the bed similar to this with a thin cutting wheel in a grinder to change it last week. It was so nice to hit the key and it started right up.

If this work was known to be done and in some states that are very strict or picky with the annual inspections this cutting your floor to do that job would equal a fail, unless the proper mending of the cut piece of floor was done right.
@@RustBeltAuto yeah I guess it would be hard to know it was done that way but if for whatever reason they found the floor was cut open and not properly sealed, that's clearly a safety violation.
@@fordwindsor351 i worked on a lincoln once. Took over 2 hours to drop the tank to find a hole cut under the seat. The dealer did it years before under warranty.
As a guess, normally if it is pegged over full there is an open circuit (broken wire/bad connection). Under E, or stuck in the same spot is a sender in the tank. If it is erratic, and doing senseless things like it is posessed, there is probably a gauge issue.
@@RustBeltAuto Sorry bout that, I was being lazy and did do what I learned over the years. It was plain as day using my experience and power probe. Thanx for the vid my fellow tech💯
Crimes pays but botany doesn't is one of the greatest youtube channels.
Agreed
Thanks for sharing your video I have a 99 Tahoe as well I love the way you accessed the pump you just saved me a lot of time
Interesting story, creative approach to the pump. I find the excess fuel in exhaust confusing, but it is hard to argue with results.

Great video
This is a very smart way to do the fuel pump. Like.
Im about ready to cut a hole through the floor like you did lol. I miss my subaru
Thanks for the thorough explanation of the flame front. Shit always baffled me but your wording was spot on!
Love living in Arizona . Both my 2 door tahoes have no rust at all.

High speed metal air saw.
@@RustBeltAuto Awesome thanks. I'm going to try a nibbler to keep the mess down.

So I'm going to cut a hole in the floorboard as well but what is the easiest way to make sure I line it up correctly?
Make a small hole, and look in it. Good luck.
Do you have to replace the connector with the one provided or can you just use the factory plug?
@@freshbutplain1144 the original connectors can wear from heat. Like a toaster.
@@RustBeltAuto ah okay if it seems okay I’m fine with reusing it? Thank you 🙏
This is fantastic! If I wanted to seal the seam so nice ductwork aluminum tape is cheap!
I'm trying to understand what the center connection is used for between the fuel lines.
EVAP?
LoL, I came here hoping you did it like this. I really just needed to know where to cut the hole in the floor
Helped me a ton! Thank you
😁
What is the red tool you used to remove the hose
You mean one of these?

How would they know? If it was a victim, I would probably do it differently too.

@@RustBeltAuto Very interesting lol
when you were removing the rust from the tabs , fragments were dropping in to the fuel tank, this is not good
Brilliant observation.
@@RustBeltAuto lovin it 😅😂😂😂
I have a 99 Tahoe gas gage doesn’t work any suggestions

Thanks for the vid!!
Great info here
Very nice
What’s that tool called?
What tool?
Good job ! Did that before.
Good work man. Lots a good information !! And i love your bodywork hahahahahaha
Were you in that Movie "FARGO".....???
Just the reality of it.
Thanks got the vid!!
my point of watching the video,was the wiring. the color codes are off on the new set. you should have explained that😑
Some of those connectors I have done had 2 wires that were in the wrong spot on the pump module.
@@RustBeltAuto Sorry bout that, I was being lazy and did do what I learned over the years. It was plain as day using my experience and power probe. Thanx for the vid my fellow tech💯
To this day, we DONT drop tanks!!
👍💯👍
How much did you pay for the fuel pump
I can't remember
I thought acdelco pump was the best
Delco is nice.
Why
Because why not.
Yo
Dougamahikki lol
Dude what are you doing? SPARKS!!! You're hitting metal together next to a giant pile of gasoline!!!!
Be brave. Do something.
Pile of gasoline? It's a pile? Ues your the smart one
