i have a 89 ta originally had 305 now has 350 supposedly bored .60 w/ mild cam ( supposedly came as crate motor) previous owner use all components needed from the stock 305. i since have replaced the prom to one for a 350 and am currently seeking info on the fpr and injectors
the car will run 20 min then stall i have been told to try replacing the fpr BUT being that it has a vaccuum hose on it i cant believe it is affecting the fuel pump.

Monitor what is actually going on by a combination of data-logging, wide-band O2 sensor, and gauges, like a fuel pressure gauge.

Is your fuel tank properly vented? Do you notice excessive vacuum when removing the fuel cap?
What is your fuel pressure doing during operation?

not really sure what you mean by wide-band o2 sensor but when the car was running a mechanic friend of mine said the fuel pressure was within specs of course this was before it started stalling. question is i was told from another mechanic to replace the injectors , the fpr then possibly the fuel pump problem is money to do everything without being sure it is what the problem is. as far as the fuel tank pressure etc i dont believe there is excessive vacuum and as far as i know it is stock. is it possible that sea foam could have caused a problem???
