I have been having fuel delivery issues on this blazer since i've had it. It's a gen v big block so there's no mech fuel pump provision. The p.o. had a little Mr. Gasket geroter pump on the frame that works but I can run the carb dry if going up a long grade or getting on it. Carb float level is good. I want to upgrade the pump but I do plan on going to efi eventually. So this is my tenetive plan. I'm going to install a Beans sump in my tank. (I have one on my diesel duramax and I love it.) From there 8an to 100 micron filter to bosch 044 with output check valve on frame rail. Then 6an to 30 micron filter to holley 12-880 regulator to carb. That way when I go to efi all I have to do is swap out the included spring in the regulator and its good to go. What does thou think??
