Anyone running this; Walbro HP Fuel Pump 400lph High Pressure Pump
I just purchased one from the RX7 store. I really don't need this much flow, I'm not looking for that much power. What I want is the 80 PSI and good flow. I just installed some ID 725/1000 and the documentation says these perform best at 90 PSI. My current pump won't get past 60 PSI. So I plan to run 80, with a 1:1 so a top of about 95 PSI.
I'll let you know how it goes. Yes I have done some fuel upgrades. I'll post that soon.

The Walbro 400 has been looking good. As the above thread shows, many people are having success with it. The real issue with most of the Walbro's is reliability. Hopefully things work well for ya.

Hotwheelz, Thanks for the thread.
XLR8, You Assume correctly, Lines/fitting are good for 200 PSI, at least advertised for that. Additionally I have decided to make the base pressure 60 PSI (nipple not connected) and then about 75 PSI at full boost.
tom94RX-7, I'll let you know, but ID says 90 PSI is best for these injectors so I don't think they will leak, and I "should" be able to keep the idle sufficiently lean, as I believe the aeromotive FPR reduces pressure under vacuum, and the lines are designed for 200 PSI
I do have a concern about it being a knock off after reading the thread. My pump looks just like the one in the pix. I don't see anything on the pump that indicates it was made by Walbro. The packaging is all that says Walbro. Bought mine from the RX7 Store for 157.00 shipped.
When I searched on the part # I got these two main pages;

TI automotive as the Manufacturer and a lower LPH, seems strange, but I don't know if Walbro is just a licensed brand or what?

This one talks about hot fueling, similar to the RX7 store text.
The new 39/50 DCSS pump has been designed around the proven 39mm armature ("motor") that has been used for many years, Coupled with the proven armature are two sets of turbine blades set in paralled on a single impeller shaft. This design allow fuel to pass through two high pressure pumping channels delivering fuel in a manner to work with the high pressure demand of today's direct injection system.
Technical Pump Specifications
Overall pump lehgth: 121mm
main Housing Dia.: 39mm
Lower Housing Dia.: 50mm
Fuel inlet Dia.: 11mm OD
Fuel Outlet Dia.: 11mm OD
Flow rate: 400LPH @ 40PSI
Test Voltage: 13.5 Volts
I plan to install the pump, and I have a good FPR and gauge, hopefully all will be well.
