The fuel filter is an inline type between the fuel pressure regulator and carb. It has 3/8 inch connections.
This does not seem right to me. You should minimize restrictions after the regulator. What side of the fuel filter are you measuring your fuel pressure? Does your filter see a lot of engine heat?
Do you have a picture of the under hood stuff, line, regulator, filter, and fuel pressure pick-up location?
I've run a Mallory 110 pump on mine (7.60s to 7.70s) and the pump could not keep up. I know others who run a 110 pump that are faster than me without any problems - the devil is in the details of the entire fuel delivery system and mine is fair at best. However, my problem was not intermittent or weather dependent.

Thanks for the tech support on this.
Just did the fuel flow test into 5 gal bucket. Measured the fuel flow on the final connection into the carb. It took 3 minutes and 45 seconds to flow 5 gallons. This comes out to only 45 gph. Please check my math on this to be sure I am correct. This surprised me since the pump is rated at 110 gph. I thought it would do at least 60 gph.
The fuel filter is currently located between the regulator and the carb. I am going to relocate it to between the pump and the regulator and repeat the test. I will report back later this afternoon or evening.
Thanks,
Roger
The pump is deigned to flow unrestricted (advertised
flow)
so it will be less with the regulator in line
