Fuel pump died. Replace or upgrade?
 
After 4 years of miata ownership I had my first 'wtf why won't you start' morning a few days ago.

Fuel pump is dead at 99,000 miles...

The car is still NA, but has megasqirt, flat top, exhaust parts, etc.
If I mod the car any farther it would probably be ITBs, e85 and moar compression. I have a subaru LGT to scratch my boost itch.

Replace the fuel pump with OEM replacement, or go with a better aftermarket on?

I just had a pump failure myself, (a 7 month old walbro on E85) and will be going to deatchwerks fuel pump next. They are turbine style pump, and supposedly high quality. Website said it has a 3 year warranty, which was surprising. You probably won't need more pump, but if you go e85 perhaps.

I have an extra DW300 if you want

You have no need for anything more than a stock pump.

Why not just do a Walbro 190HP. Pretty cheap and might as well just do the job once.

I'm only 133whp on e85 and that's what I'm using.

I have a DW200 laying around if you want a quiet mild pump! This shouldn't overwhelm the stock regulator.

Walbro 255. Nothing else, do it.

I was faced with the same decision and went with a DW200. I think it was about the same cost as a replacement from advance auto. I've got a year or two on it with no issues.

DW100 is what you want. Silent and less flow than the DW200 so you won't overpower the factory FPR.

Looking at the walbaro 255 pumps. The universal kits are more expensive than some of the 'fitted' kits. Same pump, but different sock shape/inlet nozzle.

The miata might be getting a fuel pump for a 1992 mustang....

whitrzac 07-20-2016 08:13 PM

Option B is to buy a DW300c for my legacy and move the DW65c to the miata.
I'm not maxing out the pump, but there are a few flex fuel kits coming out for the LGT now that would need a larger pump....

Walbro 255 is installed. Came with the 'install kit' for a 1999 subaru impreza. It was $42 on amazon...

I had to completely rescale my VE table. Autotune was a godsend again.

Arca_ex 07-25-2016 11:11 PM

42 bucks on Amazon probably means it's a fake... hopefully you have some sort of lean out failsafe when it starts to die.

whitrzac 07-26-2016 06:58 PM

Like the stock one did? /sarcasim

I didn't check it over that well, but the pump/gear setup inside was metal. It looks like there is no way to tell a fake without destroying the pump.


Arca_ex 07-26-2016 10:06 PM

It's pretty easy to tell actually. Price, and not buying it from an actual Walbro dealer. Should have just gotten it from 949 Racing or some other reputable vendor.

Don't buy walbro pumps, got it.


Anyone want to take bets for the over/under on how long the pump will last?

Really, that's what you took from my post? I'm not saying don't buy Walbro pumps. I have one. I'm saying don't be a cheap fuck and buy fake ones.

aidandj 07-26-2016 11:24 PM

Lol. Definitely fake.

Reading comprehension fail too.

In for more fails

whitrzac 07-27-2016 09:06 AM

I don't have to worry about fakes when buying a DW or AEM pump... Walbro says it will price match any genuine pump, but won't give a list of the places known to sell fakes. Why buy a Walbro and risk getting a fake over a DW or AEM?
It's a non boosted miata, when the pump fails it may not even ruin my day.


Price is back up to $70 from the seller I bought it from
