So our '02 Tahoe has been running out of fuel while the gauge still shows about 1/8th or more remaining. I did a search and found a TSB about the common failure of the fuel level sensor/sender but it didn't include any info for the flex fuel vehicles. My wife's truck is the flex fuel type so it has a different part number for the level sensor. The one I found is 88966958...is this the right one? $119 for the damn sensor better make the gauge accurate again

 

88966958 - thats the right number you have there...no worries...

 

beat me by 1 minute big red... had to start my gm system back up

 

Red99..... taht is the sensor kit itself though... and if the pump is already starting to make noise you may wanna go for the full sender assembly 88966962 or acdelco number mu1378... taht is the full sender and pump assembly that will drop in..... the other part you have to take off your old sender, and still use your old pump.

 

Thanks for the quick help guys. My concern right now is the sensor being inaccurate however I've read stories about these pumps failing w/o warning and then you're stuck towing it home to fix it. My wife daily drives this and it's at 75K w/ the stock pump. It's not making any weird noise but I don't want her to get stranded somewhere on the highway. Maybe I'll just replace both while I've got the tank down.

 

That number i gave you is one drop in assembly... it replaces both ion one piece....

btw if you want the pump to last... please do not run it below 1/4 tank... if you do the fuel pump WILL overheat and go bad very fast.... the pumps will last forever but they use the fuel to cool them

 

Since the part # issue is cleared up..I will hijack.

My 02 Tahoe has been getting harder to start after sitting for several hours. Instead of turning over after 1 second of turning the key it takes 2-3 seconds. I am on the stock fuel pump w/75K or so miles. I also have an inline 255lph pump. Fuel pressure is still good at WOT but at idle it seems lower. I just replaced the FPR and filter and nothing changed. Think the stock intank is giving out? If the stock one did quit would the inlnie still do the job until I get it fixed?

 

i think it would do the job for a little bit, but would probably tax it pretty well....dont consider that written testament though....

 

is the inline below the tank level?? if not then it will strain the inline, and kill it very quick.

even if it is below.... you need to check the connecter at your fuel pump module.... the plug is very common for getting corroded, and causeing bad connection... please check that first.

but if your intank does go out... i would definitely replace it right away..... an inline is like a ticking bomb.... you never know when its gonna go...

and once you replace your intank, keep it ablove 1/4 tank or more..... I cannot stress this enough!!!! the pump is cooled by fuel!!! so imagine what happens if the tank starts to get empty?!?!?!?!

 

Where would this connection be and what does it look like?
