Oil pan and Fuel tank baffles?
 

Does anyone make an oil baffle plate for the FDs? I know the RB has them for the FCs, but what about the FDs?

Also are there baffles in the fuel tank of all the FDs? Or is it just the 94+? Is there anyway to add the baffles, or mush you repalce the tank?

Anyone?

I would be interested in the baffles for the fuel tank, but how would you get them in there.

The oil pan already has a baffle plate, however its horizontal. The gas tank has a plastic one as well, it's more of a box type but it does a decent job. If you want a better one, you will need a different tank.

Yeah, the stock FD oil pan is heavily baffled. I do want to say I saw a baffle plate at some point, but I don't think it would be necessary.

The fuel tank is baffled, the oil pan is heavily baffled. The oil pan baffles aren't just plates but entire steel "ballons" that displace oil with air to make the oil level higher without adding tons of oil.

The fuel tank baffles are all the same for 93-95 as far as I know. They are all steel, there is a plastic fuel cup that the fuel pump sits in. In 1996 Mazda added a small steel cover to the plastic fuel cup that the pump sits in. I have a new 1996 fuel tank from Mazdaspeed Motorsports that helps fuel starvation during autocrosses. I used to have to run AT LEAST 5/8 of a tank of gas or suffer starvation problems, now I've run it to 1/4 tank before I've had any starvation.

Did you ever take pics of the difference in the later tanks' baffling, Jeff?

Honestly I don't remember if I did or not. It isn't rocket science though, it is a small steel cover over the plastic fuel cup with a hole in it for the fuel pump/pick-up.

Looks like a square baffle with a maze like entry that starts at the right front, entering the main topless box at the left front?

my $02 would be a "turbojeff" sump/bucket kit that attaches to the pump. Pump would sit in bucket, which has a bosch pre-pump on the side, powered off main pump, that keeps the bucket full. pre-pump has the filter sock on it. return flow could also help fill bucket.

any interest in a $150 in-tank kit that uses current pump and ends starvation? I'd get one.

Jeff, I had the same poblem when I was autocrossing. Scarred me quiet abit when it first happened. Luckaly there was a couple rx-7 guys there that mentioned to me about the low fuel leval problem. Is it the new fuel tank that fixed the problem or can I buy just the small steel cover? Has any one starved ther fuel pump under straight aceleration? I think I might have but not shure.

I think that you can buy just the cover, it should fit some 94+ cars, possibly all 95s. The few 93s I've looked at do not have the plastic tabs to mount the cover. Of course you could fab something up to make it work anyway.

The cover is something like $270, the new tank is something like $350 (prices could be off but relatively they are close). I went for the new tank:).

I guess it is all in the terminalogy, the part he is calling the fuel tank baffle I am calling the "fuel cup". There are bigger, steel baffles in the tank in an X-pattern IIRC.

Didn't your stock fuel tank have rust or broken baffles in the tank as well?

Dale

I've seen two different cars now that had the large steel baffles break inside the tank. I checked mine recently and it's loose at one end. Probably only a matter of time before mine breaks too.

I have a 93 so it looks like I should go with the tank. thanks jeff

No rust what-so-ever. It did have broken steel baffles.

Jeff

I know this maybe stupid...but whats a baffle????

turbojeff, do you think the price justifies the tank swap?

I just was not sure if there was an oil baffle plate like the FCs have (aftermarket that is), or if it is really needed.

I wouldn't buy a new tank just because, unless your auto-xing or open tracking the car. My stock steel baffles failed so I just bought a new tank.

The factory FD oil pan baffles are quite a bit better than the aftermarket FC baffle.
