“Mazda 1994 rx7 fd3s pulsation dampener failure. Caused loss of fuel and damage to wire harness. The fuel leaked onto and into the wire harness and caused the harness to become saturated, damp and brittle. I also had to pay to replace and install new pulsation dampener, wire harness, intake gasket and a few other parts do to the pulsation dampener failure. I also had to pay for labor. Total was around $1600.00 usd. I am not happy and I hear this damper fails all the time for my local dealer.”
NHTSA complaint #10212593, filed 2007-12, 147,900 miles“I came extremely close to an engine fire. My engine bay was soaked with fuel. Now half the engine has to be taken out in order to fix this problem. I shouldnt have to fix this. The RX-7 has been around long enough to be able to come up with a suitable fix for this problem. I dont want this to happen again. It is very dangerous. Why is this not on the fuel system recall fix list. It is know to fail.”
