[DML] Re: Need guidance regarding gasoline leak

["Marv Hein" <marvhein@xxxxxxxxxxx>]

I really appreciate the original question and your answer.  

I just replaced the fuel pump in my car when it died, apparently from 
overheating.  I also replaced the upper boot, which was rotted out.  
The lower boot was in great shape, probably replaced the last time 
the fuel pump was done.

Whoever replaced it for the previous owner (maybe he did it himself) 
used a couple of nylon ties around the base of the lower boot and 
nothing where the return line passes through the lower boot.  None 
the wiser, I put my new pump in the same way and, while I tightened 
the new ties the best I could, with the upper boot removed, I have 
also seen gas inside the lower boot around the pump itself.  I 
thought maybe that was normal.

Guess who just bought a nice big clamp for the base of the lower boot 
and a smaller one for around the return line?  Everything will be 
nice and dry in there from now on.

Thanks again,
Marv
