NA/NB Miata Fuel Pump Replacement - Complete Install Guide!

[@RiverstoneAutomotive]

Disconnecting the fuel injection fuse DOES NOT depressurize the lines. If anything, stopping the fuel injectors from firing will actually increase the pressure. To depressurize the system you need to disconnect the fuel PUMP, and you can do this by disconnect the fuel pump relay or even by disconnecting the connector on the top of the fuel pump since we already have easy access to it.

That makes sense! Appreciate it!

[@davegaul7165]

Thank you for making this great tutorial! Just replaced the pump on our 01 yesterday and your video made it stupid easy.

[@bradscarmods]

Woohoo! Nice work!

[@SU37]

Thank you for this awesome video

[@TheEva0225]

Great video man highly appreciated

[@bradscarmods]

Thanks!

[@iFlightz]

If i mess up the soder will i blow up??? Or pump just won’t work

[@curtismay3755]

Great video. Thank you.

[@bradscarmods]

Thanks!

[@redneckersonphd]

Where did you position the convertible top for such good access?

[@nl_mx5]

Awesome video, I just finished installing a dw100 in my nb1, I soldered and heat shrinked the connections in the fuel tank, did you use regular heat shrink too? Im just terrified now that the heat shrink will degrade and ruin my pump

[@bradscarmods]

I wouldn’t be worried. Most types of automotive heat shrink isn’t effective by fuel.

[@nl_mx5]

@@bradscarmods perfect thank you, how's the pump holding up?

[@bradscarmods]

@newfie_miata haven’t driven my car in about a year, go check my other videos to see why!

[@nl_mx5]

@@bradscarmods very interesting, the k swap is cool, good on ya

[@thepianoman9947]

I'm having problems with my fuel preassure regulator and I'm having trouble finding it. Some people say it's on the fuel rail and some say it's in the fuel tank along with the pump. I couldn't see it in this video but I would like to ask, do you know where it is?

[@pro.fanity]

Hey Brad! Great video. My fuel pump went out and I am going to try tackling the install myself pretty soon. I was wondering, what solder did you use for your install? I'm a complete beginner to soldering and wasn't sure what type of solder I should use for this. Thanks!

[@bradscarmods]

I used .062 60/40 Rosin core leaded solder

[@HammerleHomesProject]

Did this fix the hesitation when hard cornering? I am experiencing similar issues.

[@bradscarmods]

It did for me! But, I did figure out later that the OEM fuel sock that hangs off the bottom of the pump is better than the aftermarket one because the OEM one has an internal frame to keep it from collapsing on itself so I did end up buying a new one to put on after I filmed all this.

[@ibrahimeltony4865]

​@@bradscarmods That's too bad Same thing with me Also the pump was noisy Couldn't stand it and then returned to the original one 😢

[@kevinsaeed9817]

I bought the same pump. It didn’t come with any butt splice connectors. How’s that heat shrink wrap holding up submerged in gasoline?

[@bradscarmods]

The heat shrink is holding up great! No issues.

[@BearWa11ace]

I have a DW pump and I was wondering if there is any issue with splicing wires and gasoline. Anything to worry about there?

[@bradscarmods]

Not at all.

[@TheFurryFoodie]

14:05 The Rubber piece you got is accurate!! I've been in and out of Autozone and Oreilly's looking at their pumps seeing they have a 3 nipples Fake OE rubber piece. I see you got the DW200, I'm going to go with that and see if it is correct. That little rubber piece is preventing me from putting the assembly together. >:C

[@LeoTiemubol]

did it work?

[@sonoma314]

Description says fuel pump D100 908-270, the part number on the box is different, a comment says D200. Which pump did you use please?, thanks

[@bradscarmods]

I used 908-272 but there are multiple part numbers for the D100 series pump so buy the one specific to your Miata.

[@whitelightningmiw]

What head unit do you have for your radio?

[@bradscarmods]

Alpine iLX-W650

[@matthewnguyen82]

Is tuning necessary or is this a plug and play pump

[@bradscarmods]

No tuning required. It’s an OEM equivalent pump.

[@matthewnguyen82]

@@bradscarmods okay cool that’s good to know the website said it may need to tune which made me not want to buy it as I have a stock ecu but I’m gonna go ahead with it now

[@lolsmol]

So it sounds like if i just change it with OEM, I won't have to solder at all.

[@bradscarmods]

Correct

[@lolsmol]

@@bradscarmods Thank you for your quick reply! Your video is so easy to follow

[@bradscarmods]

That’s great to hear. Thanks for watching!
