davebugs Posted May 30, 2007 Share Posted May 30, 2007 I have a 94 Legacy wagon AWD who's sending unit does not work - the pump seems fine. I have a 90 FWD wagon that I pulled the pump/sending unit combo out of - 2 hoses. Is there anyway to just swap sending units that may actually work? The 90 only has a unit on the right side. The 94 has 2 units (one on the left - 1 hose, and one on the right - 3 hoses). I read here that on the AWD's the right pumps fuel over to the left side of the tank. Is the sending unit the same? I confess that I haven't removed the right side unit in the 94 AWD yet - I hate to make a mess that I can't tidy up and fix correctly.

Legacy777 Posted May 30, 2007 Share Posted May 30, 2007 FWD & AWD sending unit assemblies are different, and can not be interchanged. Quote Link to comment Share on other sites More sharing options...
davebugs Posted June 1, 2007 Author Share Posted June 1, 2007 I know the assemblies are different. At first glace the sending unit part looks the same. Tomorrow I hope to get the 2 of them together and perhaps try a swap of the sending units since they are both out to see what happens. If I get them to work ( or not work) I'll post the results here.

Legacy777 Posted June 1, 2007 Share Posted June 1, 2007 The sending unit itself is different as well. The FWD unit has a resistance of around 0-95 ohms, while the AWD units have a resistance of around 0-45 ohms each, which gives a combined resistance of around 0-95 ohms.
