what fuel pumps are you guys using when you go single, and are you having any problems with them?

Nipondenso. Don't know... Haven't started the car yet! LMAO

supra pumps

had one go out a little premature, but i made enough sound and gradual fuel pressure loss at high rpm when it was going bad that I had time to fix things.

running dual walboro 255lph high pressure pumps now for over 2 years.. no problems.. TONS of fuel just the way a rotory likes it.. https://www.nopistons.com/forums/pub...#>/biggrin.png

2 Supra pumps. Haven't driven it enough to find out if they'll be a problem. Given the fact that they're OEM Toyota products, I'm not worried about it.



They use a lot of current though. I tested them and they draw 12 amps each https://www.nopistons.com/forums/pub...IR#>/blink.png

i have one big SX external pump

Aeromotive A1000 external.

Big fat Bosch '40 pump. It's good enough for the 930's, it's good enough for me.

Single ND is problematic at above 60psi...drops off with the stock lines. Dual Wally's would work with upgraded lines.
