<VV> Fuel Pump

[Mikeamauro at aol.com]

"...I have had bad luck with Clark's pumps and very bad luck with pumps  from 
any other source (I think there are still a lot of those faulty pumps  in 
the general commercial system)..."

 
I've bought innumerable fuel pumps from vendors, and they usually develop  a 
leak whereas fuel begins seeping, and then dripping, from between the  
diaphragms and the metal sections of the pump. In the past, I would tighten the  
screws on top of the pump cover, and the leak world stop for a few weeks...then  
come back. I'd keep tightening until, inevitably, the threads in the lower pump 
 body would strip...then back to vendor for a replacement, repeat  scenario.
 
The FIX: Several months ago, instead of sending a pump back to the  vendor, I 
disassembled it and installed thread inserts into the bottom  housing, 
reassembled, installed, and the pump has been leak free since (now I'm  probably 
jinxing myself). 
 
I've told the vendor about the Fix, but never received a  response-- good, 
bad, or indifferent.  Anyway, the reworked pump  has been leak free in this 
particular vehicle (wife's daily driver  Greenbrier) longer than any other pump 
ever has before it. With a few  months to go for a year in service; if it makes 
a year, I'll consider the Fix a  Cure.
