Does anyone know what fuse #29 powers? Its a 7.5 and keeps blowing. I do have a CEL on related to a low evap signal. Wondering if this is related to the fuse. The book show nothing.2008 XC90.
Thanks for any help,
Steve

 

This? I have no clue what "feed pump ejectors" (not injectors) is - anybody out there have that knowledge? What market is this car in, is it a bi-fuel car?

 

Just a standard 6 cylinder US car.

 

I recall seeing something for V70Rs where the ejector pump moves the fuel from the left side of the tank to the right side, with the primary pump sending the fuel to the rail. Dunno if that's the same design for the XCs and other AWD cars (is there a recess in the bottom of the tank to make room for the rear wheel drive???

 

Looks like that's the case - part of the fuel pump assembly on cars with a fuel pressure sensor and a fuel pump controller.

 

brilliant! Thanks !!! Is there a part # for the ejector pump? Or is it part of the fuel pump? Also, what is the 4/58 - rear electronic module that f29 goes to first? Couldn’t seem to find it in any parts diagrams. I will have to see if the fuse blows again which most likely it will. This may explain why for years my car would stall out when I got low on fuel- around under 60 miles and under . The ejector pump wasn’t moving fuel to the other side. So my solution was to never let if get below 80 miles left in the tank.
