| First off i thought you guys cared about the cars we drove, then how come you allow this to go on without a recall it amazes me how stupid you guys have to be to let this one just slid on by. my damper is leaking fuel right as i type this to you. if i drive my car it may catch fire and kill innocent victims. please make this problem a safety recall for dealerships to fix at their own expense. this failure is extremely common on 86-88 mazda rx7's, and mazda knows about it. why should i have to pay for keeping my vehicle safe if it is their problem. so many victims, should i be the next one? please make this a manditory recall so i can make my car roadworthy once more. i am affraid that my car will catch fire in the near future. the pulsation damper is mounted to the fuel rail of all rx7's and all rx7's have a risk of burning to the ground. i have seen so many cars like mine in the local junk yards, blood on the driver's seat, fire damage everywhere. mazda even made an improvement on the replacement piece so that it will never leak again. i need that new damper right now! *tr | |||

| I routinely started the car for a nice sunday drive and while i was waiting for the car to warm up i noticed fuel leaking on the ground. i immediately shut the car off and discovered that fuel had leaked all over the top of the engine and was running down the side and onto the exhaust. the fuel leak was coming from the fuel pulsation damper located on the primary fuel injector rail. i can buy a replacement part which will fix the problem, however, i have heard many complaints about this part failing on a regular basis so in order to reduce the risk of a fire due to a leaking position damper it is a good idea to replace it every 2 years. if this hadn't happened in my driveway i might be an unfortunate victim of a car fire. *tr | |||

| I own a 1987 mazda rx-7 turbo ii with 44,500miles on it, the pulsation damper on the fuel rail started leaking and left a small puddle of fuel on top of the engine, and on the floor. i have read that the pulsation damper often fails in these cars causing fires. i would like mazda to recall this part and issue me a new/updated/safe part. i have already replaced the failed pulsation damper with a banjo bolt to eliminate all chances of a possible fire/fuel leak. but i think mazda used a pulsation damper for a reason, and i would like to keep my rx-7 as original as possible. *tr | |||

| I own an 87 rx-7 n/a. there were no events leading to the failure i filled up at the gas station and drove off after about an hour and a half i smelled fuel. so i pulled over to inspect i shut off the motor and the smell came from under the hood. i quickly opened the hood and to my surprise there was a small flame. luckily i was able to put it out using my shirt. the culprit was the fuel pulsation damper the screw had fallen out of the end of it and into the cap letting the engine cool i then put the screw back into place and continued driving. only for the same thing to happen again minus the fire. i screwed it back in and tightened it the best i could and it happened again. at this point i was home so i looked around the garage and found a fuel rail from a 91 honda civic and i took the fuel damper off and removed the screw cleaned it and replaced the o-ring on it. i then replaced the one on my mazda with the honda one its held for going on 6 months now. no more leaks. *tr | |||

| The pulsation damper has a screw that in time works its way out. once this screw falls out, fuel leaks out all over the engine/intake/exhaust manifold. i have already heard of several other people in the u.s. through the internet who have had the same problem. among owners, many know about this hazard which could occur at any time or any speed. it is a major cause of engine fire and very dangerous. my vehicle has now suffered a fire caused by this defective part. i was lucky enough to have already shut the car down, got out and away, and to have put the fire out before it burned everything. | |||

| My pulsation dampner on my 1987 mazda rx7 is failing. it is a very weak part and easily susceptible to failure. the pulsation dampner in my car has failed and allowed gas to leak into the engine bay and onto the hot exhaust, thereby resulting in a fire. it was caught early and not serious, but i smelled burning gas and luckily found the problem before it ignited other gas. *nm | |||

| The pulsation dampener on the 1986-1988 mazda rx-7's can fail. the piece is made from plastic which becomes brittle and fails. this will cause a fuel leak in the engine bay and cause a possible fire. *nlm | |||

| The starter had given out. i and a friend were in the process of replacing it. the friend smelled gas. i got under the car, and smelled gas also. we decided not to drive the vehicle until the source of the smell was determined. after removing the intake plenum, it was determined that the gas leak was from the pulsation damper, a component bolted to the end of the primary injectors fuel rail. it was leaking onto the passenger side of the engine, near the top. since the engine is oval, the gas was running down the side of the engine toward the exhaust manifold, which becomes extremely hot when a rotary engine is running. although this had not happened yet, as the leak became worse the gas would have ignited, putting the driver and passenger in the car at great peril. this component should be engineered in such a way that it does not leak, even if it fails. there are many incidents where a vehicle has been completely destroyed by fire as a result of the failure of this pulsation damper.*ak | |||

| The small screw in the end of the pulsation damper had fallen out. other persons with this failure have had fires as a result of this. in my case, i simply replaced the part. it failed again about two years later... again, no fire, but it was leaking gas. *ak | |||

| I am an expert on the 2nd generation 1986-1991 rx-7 vehicles (see http://fc3s-pro.com). i find these pulsation damper fires too common with serious/expensive damage - typically will burn wiring harness ($1,200) and all fuel injectors (4x$300) under the manifold. mazda and all mazda dealers refuse to acknowledge this problem. i wish there was a mandatory recall on this part, as the potential of engine fires is way too dangerous. please feel free to contact me. i am also very close with the internet community of these owners. *ak | |||

| Dt: the contact states that he owns a 1987 mazda rx7. he states a recall came out nhtsa campaign 05v317000. contact's vehicle was having the same type of problems with his gas gauge working intermediately and a fuel leakage. just recently he replaced the radiator with a new one. took vehicle to a mechanic and they told him that the fuel system would needed to be replaced because no fuel was getting to the lines. also, the modulator needs=ed to be replaced because it was not getting a spark. he replaced alternator and starter. *ak | |||
