I just purchased a 190 HP fuel pump from Lightning Motorsports, and used an old coupon code that I found, which made the shipping free. HTPUMPFS, final price of pump with free shipping $84. I also think it's a good idea to give props to this site in the notes section of the order since they seem to be the place that is recommended on this site for buying the walbro pumps. If enough of us say that we were referred from here, then maybe they will extend us a permanent free shipping code.

 

Thanks for the heads-up! I'm now $84 poorer. I've been needing an excuse to pick up a replacement pump for my '90.

 

Glad I could help. Just changed my fuel filter after testing my fuel pressure. 35psi idle, and 65 psi max. Fuel filter change made no difference. Oh well, 20 dollar piece of mind I guess. I kept noticing a stumble at higher rpm and jeremy at flyin miata said my maps looked too rich if my fuel pump was working properly. So I pulled the trigger on a new pump. Fuel pressure looks a little low anyway. (even by stock mazda specs) No carpet in the car makes changing pump that much easier.

 

Ordered Saturday, delivered Tuesday. Sweet! Not bad for free shipping!

 

GCA3315-2 Miata 1994-97 190lph will this work on a 99 i have found 255s but i dont need that much? does anyone know where to get a 190 with the 99 harness?

 

I found it here Fuel Pump Wiring Pigtail (99-05) if anyone else is looking.

 

So what do i need to order for a '90? Thanks
