installed my 255 walbro fuel pump, went in just fine, no problems....... untill i fired the car back up and now my gas gauge won't work! took the assembly back out, nothing out of the ordinary, so tried it again, nothing. anybody know what my problem could be?????

not really an emergancy, but would be nice to know how much fuel i have


thanks.

 

it has to do with the way the fuel pump and filter work together, never really worried about it... cuase you can know from mileage... technically... but that's why it's an issue..

 

Heh heh. Just fill up every week, if not sooner. That's what I have to do on my Vespa, which has no fuel gauge.

 

did you remove the level sensors or disconnect the wiring when when you did the conversion?

 

the thing is there's one on both the pump and filter.. and the voltages work together... etc etc balh blah... weeeee

 

am gonna take it apart again soon, re-check everything. all wiring was good ;ast time i looked...... will let everyone know whats going on

 

I know how it works, but maybe this guy doesn't. Obviously if he removed it with the old pump he has his answer. I haven't tried the aftermarket pump, but this seems like a pretty easy thing to diagnose.

Bmw makes many versions of these sending units. Some are seperate from the pumps. I'm am sure you could find one to retro fit if the stock one can't be modded.

 

NP np.... I was just being specific for the over all reader...

 

NP here, dang interweb doesn't express my tone well.

 

Five year old thread, pumping some life back into this. It's a longshot, but I hope Zmanrz could shed some light on this. Was this ever sorted? Is the Walbro still good? Any 1st hand feedback & long term review would be very helpful. I'm curious about this lower cost pump replacement option. Thanks!

 

Theirs not much that fits into the stock mini enclosure, it can be done but its a bit of a pain in the ***, as far as the level sensor, i usually cycle the key once or twice and it re sets the fuel level sender, if i have everything connected up, however another pitfall is the circuit board for the center that it rides on is easy to break and can be broken putting it back into the tank.

 

Thanks for chiming in Colin. I presume you have 1 in? How many miles & how long has it been? Any benefits or performance improvement noticed? Or, it isn't worth all the fiddling & headache? Thanks!
