Fuel smell only under boost.

Replaced FPD - no change.
Replaced brake check valve to vacuum line - no change.
Replaced PCV valve - no change.
Replaced FP regulator - no change.

The above were over a period of 5 years.

A few days ago, I was installing 850cc into the primaries. The 550cc were replacement under warranty 5 years ago.

Guess what, there was a rubber o-ring with a rectangular cross-section that mounts up to each of the metal pipe of the primary injector housing. I looked into my hose rebuild kits from Malloy and found them. Installed one o-ring into each pipe, mounted the 850cc. No more fuel smell under boost.

Reason - damn Mazda grease monkeys never installed them in the first place. So if you're smelling fuel under boost and you ran out of things to replace, try replacing this o-ring.

 

good job, I'll see you this friday at the tuning session

 

intresting.

 

Wow. That is almost as bad as my Mini dealer who installed the passenger side strut in the driver's side. Can you say 'negligence'....

Give a shout if you ever need a hand.
