Rare fuel pump? Kyosan 0810 390lph @14v+43psi

[wraith]

I did not use the Supra. My Supra failed after almost a decade, and I bought the Kyosan as a replacement but also ordered a new tank assembly from Mitsu because my old one looks crappy, and the wiring looked weak. I got the assembly before the pump and had issues with the car idling and at WOT so instead of introducing new issues my replacing the stock pump with the Kyosan, I just put the assembly in with the OEM pump. However, now that I know the issues are somewhere else, I am planning on putting the Kyosan in. I also put the stock pump relay back in the socket. The socket used to get really hot with a jumper and I kept blowing relays on my re-wire, so I put it back to stock. I think the old Supra Denso was drawing too much current because it was stalling and it eventually just failed. The stocker doesn't seem to make the relay socket hot and since it works well at staged voltage, its also not re-wired.

Cool. Let me know how it works out for you. I will be keeping the Denso/Kyosan for future, personal use.

The 2 Kyosans i installed were not green, and didnt have any numbers scratched off so i wouldnt be too quick to assume you have one there

It is exactly as described by the Silvia board. I can easily assume that this might have been a modified pump from early on since it does not match what their site presently shows.

Reference:

Same number you have first 5 ground off xxxxx 0872 The "Denso" is fairly clear on some of the pumps... I'll probably send one out and have it flowed... BTW, I am over in the United States. Thanks for the replies....

The results are in... it's the real deal, 40psi 13V it lays out 300LPH, and at 14V 390LPH...

Oh well thats cool then. Nice freebie

I know the HKS denso pump looked a little like that which was basically a modified Denso Supra

I've heard of these, and heard they don't have the trademark walbro whine. I'll be going with one when my build is finally assembled. They seem pretty epic, especially for the price.
