Replaced both Fuel Level Sensor/Sending Units. DIY with pics.... - Page 5

jkahng · 10-04-2012, 10:48 PM

fit the rubber gasket on the inner rim of the tank first and slowly slide the pump in place. the pump has a spring on the bottom that should stay if you installed it right. it should be a very snug fit.

i made the mistake of trying to fit the gasket on the pump and attempted to force the pump in.

it seemed like it worked but it didn't
i found out the hard way the first time i filled up yesterday.

the gasket keeps the fuel from spilling over when full. now the right tank is always full as our suction system pumps fuel from the left to the right continuously.

my car port has melted asphalt from the gas split overnight

i have .. a problem(e46 diesel 2004) i think with this pumps ,when i have poor gas in my car, my cb show me i have left to do 30km.. if i let the car few hours , the cb show me i have left 100km and if i go ride , the cb goes up , 100,110,150 km , after it`s goes down .. the sign of gas goes up and down ( same with computer board value )

1. i can take out the floating to clean it and the sensors?
2. i must buy some new floating ?

i know at back passenger is the floating for 1 - 1/2 and drive seat back for 1/2- 1/4

i can open up only the passenger floating to clean ?

i`m sorry for my bad english !

For step 9, do not use a screwdriver. A better choice would be a socket on the end of a hand wrench. It will go MUCH faster as there is more surface in contact.

Mileage is 113K and I've been experiencing similar issues the last couple of weeks. I replaced fuel sending unit and pump today - problems resolved. TKC, thanks for the DIY tutorial - extremely thorough!

^ any difference now with how the car drives? how is the idle, etc

jayriv72 · 10-19-2012, 11:30 PM

Idle hums around 600 and very steady. Acceleration is smooth and without any n

jayriv72 · 10-19-2012, 11:32 PM

...without any noticeable hesitation or lag. I've yet to drive it around a bit to determine if MPGs have improved. DTE no longer varying 15+/- miles at idle as well.

Solidjake · 10-19-2012, 11:33 PM

Awesome. Thanks!

Solidjake - No prob. In "diagnosing" the problem, I stumbled onto one of your DIY videos on cleaning the ICV. Perhaps, I'll consider doing this as PM sometime in the near future, unless you don't feel it necessary.

Worth cleaning regardless if it was never done. A lot of crud builds up in there.

jayriv72 · 11-10-2012, 03:54 PM

Surprisingly, it wasn't as cruddy as expected or illustrated in other DIY posts. I cleaned it out anyway. I don't know it it's just all in my head, but for some strange reason - it feels as though it idles and cruises much smoother.
