C.Jett Posted January 8 Author Share Posted January 8 From my experience two things can cause a carb to flood - too much fuel pressure and junk in the tank. And "junk" includes gum or goo as well as rust or grit. As for fuel pressure, I've run 460's with 5 psi, so a 300 six with a 1 bbl doesn't need more than that. But I can't tell you the max that your Carter can take, although maybe Bill can. So if you think your tank is clean or have a good paper filter ahead of the carb, then I'd install a fuel pressure regulator. I've used this Holley unit on several vehicles with good success, but I've paired it with a gauge, like this one from AED. Gary, will this work? It’s from Summit Racing, SUM-G3032B. 4.5-9 psi. My reason is that it’s black. It has 2 outlets, can one be used for gauge? Should I set it at 4.5 and try that? Thanks CJ Link to comment Share on other sites More sharing options...
C.Jett Posted January 8 Author Share Posted January 8 one difference between the carter yf and a hammer is that the hammer never has its baseplate screws lossen up Mat, depends if its a wood handle or not. CJ Link to comment Share on other sites More sharing options...

Made a bracket to bolt on head and factory bracket. Will see how it goes. CJ. The fittings cost more than the regulator…… Link to comment Share on other sites More sharing options...

The fittings cost more than the regulator…… that looks very well done. do you know the pressure setting? I am very interested in whether this helps. I have been driving the same truck with the same engine as yours since 1991 yet never had the issue that you have. this leads me to think that pump pressure is not the issue, but no one can argue with success. drive it and see.

Thanks Mat, the instructions said the regulator was set at 6.5 psi but my gauge says 4.0 psi, while my gauge read 7 psi before, unless my gauge is wrong. Gary and I think 4.5-5 psi should work fine. I will check with another gauge later. It seems to run fine. CJ Link to comment Share on other sites More sharing options...

Worst case is that you run out of go at high RPM, but how often do you spin a 300 six to high RPM? Link to comment Share on other sites More sharing options...
