Fuel pump replacement
 

I just need help finding a replacement pump besides the one mazdatrix has. I'm running bone stock, and just need a good high pressure pump. Maybe a sending unit, I'm not sure. Possibly a regulator. Maybe even a new pulsation dampener. Mostly the fuel pump though. Are there any good aftermarket ones?

Any parts store will be able to get one.

My favorite on-line parts catalog is www.rockauto.com

Turbo or non-turbo?
If it's a non-turbo, get a good, used one.
It's cheap and pretty easy to find in the For Sale section or eBay.

I'm just looking for a good, cheap one, though.

Non-turbo. I have the absolute basest of base models ever. No power steering, even.

Non-turbos don't need higher flowing fuel pumps.
In fact, an upgrade fuel pump will cause the car to run badly - i.e. more rich.

Get a good, used one from the For Sale sections in here or from eBay.

I'm kinda iffy on a used fuel pump. I don't really like buying something that doesn't work right from the word go. I just need one that works, is new, and doesn't cost an arm and a leg. Maybe I could do used, but I don't understand how you could get a good used one. I guess thats why I'm asking for help. Thanks, and sorry.

If you wat good one, you'll have to pay "good one prices" ie. OEM or autzone prices - sorry, that the way she goes.......nothings free

Ideally one that has come uot of a running car (maybe its been hit, or too rusty to fix or whatever)

But if you can't find one from the above scenario, just buy one that you THINK is good, ie. hasn't been sitting for 6 years

Thats your only option if you're too sticky to pay the exrta 50 bucks for the bakbone of the cars entire fuel system.......

I am willing to pay for the extra cost, I just want to make sure that I have a good one. Kinda wanted to know a brand or something for a new pump.

Order one from MazdaTrix.com or a dealer like Trussville (1-800-633-8285). Be prepared to pay big bucks for a new one.

I got mine from Autozone for a very reasonable price. You can even order online. Why in the world would you go to any of the specialized online sites and pay three times the price for a fuel pump to put into a base model.

With that said, if you are planning to start doing some serious mods then I would think ahead and get an upgraded pump. But I didn't get the impression that you were planning that.

you can get one off of ebay walboro I believe for 99 bucks shipped

the walbro will make his car run rich.

ok i got my pump from tre performance and they said to keep it down run a potentiometer to the possitive wire leading to the fuel pump and that it wont harm the pump and cut it back some and make it adjustable

So buy one that does work right. Kinda obvious that... ;)

The same way you get a good used anything. Test it before you buy it or get an assurance you can return it if it doesn't work. By putting battery power to a pump's terminals you'll quickly see if it's alright. OEM pumps are generally very reliable and last a long time. People use used pumps all the time. My FD pump is fine.

Did you miss the bit above about not upgrading NA pumps?

Good idea if you'd like an electrical fire caused by an overheated pot to burn your car to the ground...

so well so i know its not the brightest of ideas but i have the stock n/a fuel pump still in good condition lol i dont have mine on a pot i really dont run any richer than normal by the way the pump in the car is a 255 lph

btw im cleaning my garage and ill let you HAVE the "old fuel pump" it doesn't have the sock on it but it was working fine just had a fuel cut around 6K i replaced several things if you want it its yours figure a way to get it its about 2 years old from what i was told when i got the car last year (2 is counting back from now not then)

I simply don't believe that. Run the car with a wideband and you will see that you are significantly richer then you should be.

As for the pot idea, what the hell was that "mechanic" thinking? Any standard pot will only be able to handle a few watts. He might have meant a wire would rheostat, but it's still a stupid idea to begin with.

first off i was running rich but leaned out and completely cut out at about 6000
and as for the whole rheostat and pot idea that isn't my idea that was his i didn't say do it i said he said you could

and btw where can you find a good wideband anyrecomendations?(preferably cheap)

i have a good use fuel pump for sale if anyone needs it, from an 88 GXL will take a vid of it working if you dont trust the quality of it.

How do you know you were running lean without a wideband?

RX-7 Store carries the AEM wideband which is a decent unit in my experience.

under heavy throttle my fiancee was behind me and with no emmisions didn't smell any fuel and it felt like a high end jerk so i replaced pulsation dampener pressure regulator and fuel pump and filter and it didn't do it again i know its richer now but i like the smell i dont know if thats messed up or not but you know

Yeah, um, that's hardly a scientific test. :)

That is true very true. It was just something small to try and figure out if it dropped fuel then leaned to where it was supposed to be. Or if I was in a good ballpark then totally dropped. The pulsation dampener did not have the plastic cover on it or screw in it. The pressure regulator would not take vacuum to adjust pressure. The fuel filter looked like it had never been changed. To top it off the fuel pump stand not accual pump was covered in rust. When i discovered the rusted stand I took the pump out of it. Then proceded to test for high resistance accross the stand and it registered somewhere around 2 - 3 ohms. Don't remember exactly this was almost half a year ago.
