Hello,

I have some problem with my AEM Fuel regulator with 2x 255 Walbro fuel pump.
With 1 x 255 I can tune the pressure with no problem but with 2x255 the AEM Regulator is fixed to 45 PSI and don't move. I cannot adjust my pressure.

Do you know this problem with AEM Fuel regulator?.

As far as I have the AEM fuel rail, How can I do with another fuel regulator please?

 

I've found the problem with yhe AEM fuel Regulator by changing the orifice.


Do you advice me to keep this Fuel regulator for 700WHP?

 

Yup you definitely want to run the .250" orifice with dual pumps. I have a Weldon A2040 im selling if you need to upgrade.
