obd-0 to obd-1 help

well since my rebuild and conversion, my gas mileage has plumeted. i mean it's really bad. i'm getting 100-115 miles per tank.

anyone have ideas on this?

How's your compression on the motor? Do you have a fuel pressure guage? Try hooking it up to the fuel filter and pinching the fuel pressure regulator return line, if the pressure doesn't rise you have a bad FPR. The directions should be in the helmes manual. BTW is your fuel pump OEM or walbro?

How about some more info, rather than a shot in the dark?

oem everything on the fuel system. i can't do a compression check till tuesday.

and i don't have a pressure guage.
