355 tpi, 24# injectors, bbk adjustable fuel pressure regulator, accel fuel pressure gauge.

just finished putting it back together tonight and the battery died after a few starts. it's starting very hard (guessing timing) but my main concern is the fuel sprays right out of the vacuum port on the regulator. there's two holes in the fuel rail for the fuel to travel to the injectors (under the regulator) but it seems that the fuel is bypassing those and going through the vacuum port (I assume this port is more of a breather than anything?)
So it seems the screw to adjust the pressure should go in more (lower the pressure), so I turned it in all the way and get the same result..
Also I was really hoping I could get away without having a prom burned for the car since I know nothing about prom work.. think that's possible?

I honestly think the fuel isn't even moving past the regulator and into the sides of the rail because I pulled my gauge off the rail (with system primed) and no hint of fuel on it and the psi didn't move.
Could it be a bad regulator? could I have installed the shim inside wrong?
I need the car moving ASAP so any responses are much appreciated.

thanks, Tim

 

Fuel shouldn't spray out of the vacuum port on the AFPR. Looks like the diaphram is F***ed.

Good luck.

 

Ok im new here so be nice! Im working on a 355 tpi myself . Just installed 24 lbs injectors an a jet stage 2 chip. Now with the chip installed it runs way to rich. If i switch back to the 305 eprom i have it run ok but idle is up an down . Also it surge with the 305 eprom. Anyone know what i can try to fix this at low cost?

 

If you switch to the 24#ers you will need a chip that is tuned to support the larger injector.

 

Tmic87TPI, Your fuel pressure regulator diaphram is ruptured. The port you refer to is for vacuum. By applying manifold vacuum to this port, the engineers were able to fine tune fuel pressure in concert with engine load. Remove the cover and check/replace the diaphram.

 

Ok thanks for the in put to all that gave me advice. Im dealing with bigger problem now. A stock eprom would work with the jet chip i got but dont know what all i can snag one from. 87 to 90 tpi im taking it ? The shop i had the motor done at said to keep the #24 an get stock chip for 350 it should support the injectors with the jet chip installed. Getting to point of (get rid of tpi an go carb) but like to keep tpi.
