Stock '74 2.0
How much pressure does the injector need to work properly? I know the fuel reg is set about 29 psi. |

The regulator lets fuel by and keeps system at least 29 psi.
My question is does anyone know at what pressure the pump kicks on? I never got my fuel pump to run right so I'm just making my own stand alone system. The pump has power whenever the key is on. But to keep the pump from running full time and circulating fuel which would heat the fuel I'm going to install a pressure switch to kick the pump off after pressure is reached. I can get any psi switch I want for about $25. I'm thinking maybe 25psi might be good. I want enough pressure that the motor will get all the fuel it needs but want my pump to have a rest and cool off when not needed like at idle. |
