• Leaky 1.6TD Injection Pump... by Dave J on 17 Mar, 2008 12:58
• Hi,
  Anybody have experience with TD injection pumps? Mine is leaking fuel
  out the vent hole just below the diaphram for the turbo boost
  enrichment device (the "flying saucer"). I pulled off the cover and
  removed the diaphram/piston assy, but didn't see anything obvious, such
  as an O-ring or seal.
  
  Anyone have an idea as to what is failing?
  
  cordially,

  Ya, that's not good.
  
  Sounds like you need to do a complete reseal as the seal you need will be in that kit anyway.

• Dan,
  
  Thanks for your response (albeit not what I wanted to hear). Which kit do I get? All I've found so far are the ones for NA pumps.

• My pump was leaking from that same spot last summer. I resealed the whole thing.
  
  Do a search. This has been covered MANY times. A search will bring up more information then this one thread could produce in a week!
  
  But just because I'm a nice guy... Here is a start.
  
  My original posting when mine was leaking.
