I just purchased and installed a new MVP Fuel Level Sending Unit #62161352617 and now, I'm unable to start my 73 e9 3.0 CS.

I bought an MVP sender for a 2002 and the white tube was missing. Fortunately the original was still good.

My guess is you’re still sucking air. You can’t really troubleshoot a problem until you make that connection properly.

True. This is a very common problem with the vintage cars which is why we supply them to the community for free. If anyone needs one, just PM me with your address and we'll get one out to you. We've already sent one to @Roman596061 to see if that helps his situation.
