When setting fuel pressure, is there a recommended elevation to place the gage. Obviously, the reading changes as the gage is raised or lowered??
Any Guru's willing to comment on this??? |

Thanks SLITS. I forget things.
realred914, are you sure you're not just seeing the needle bounce as the injectors fire? IIRC there's no dampener on the fuel system. |

IIRC there's no dampener on the fuel system. I have not seen much if any fluctiation when i run the motor, if you got good flow in the loop, variations are minimixed. at any rate I would think the gage should be at the same hieght as the fuel rail/regualtor, if you get a big change when you riase teh gage up in the air, then dont raise it up in the air, keep it low at teh same level as the fuel rail the haynes manual for the D-jet says 28.4 to 29.6 psi so there is a big window of pressure to hit. the same book says that the L jet should be set to 35 +/- 1.4 psi again a big range. keep our gage at fuel rail level and you shoudl be a.o.k. |
