Fuel Filter Recommendations

[Ronnie Smith Jr]

If you are only using funnel filters and not fuel line filter(s), ensure you do not have fuel cell foam/baffling in the fuel cell. The chemicals will break it down over time and pieces of the foam/baffling will start passing through the fuel system.

Good point, I do have that and the fuel cell is about 20 years old or more. I was thinking about buying a new one but what if I just took the baffling out? Its a Jaz cell and I see that they sell them with and without baffling. Is the baffling just for impact purposes? Does everyone run their cells with the baffling or no?

I've seen them run both ways. When I had my car backhalfed, I ran all new wiring, fuel lines and bought a brand new cell with foam. I regularly checked it to determine if their were any pieces contaminating the system. My opinion is, if you take care of your "stuff" it should take care of you. With the fuel lines, I ran a single #12 out of the cell into a BG filter, directly mounted to a BG 400 pump. Out of the pump came #10 to the BG regulator. Out of the regulator with two #8's into Y block and out with a single #8 into the Q-jet. Maybe overkill with the size of lines, however, we wanted to make sure we had plenty of volume. We set the fuel pressure and forget it. We never had problems with erratic or spotty fuel flow. Regular maintenance of the fuel system seemed to work well.

The other recommendations sound great. I am not sure you can "over filter" your fuel for any foreign debris.

Good luck with the remaining season.

My car's fuel system was very similar to Mr. Smith's except I did not use the filter. I ran the #12 (11/16 i.d.) from the cell to pump (BG 400). From there to the regulator I used aluminum 5/8ths tubing, saving a bit of weight here. I used two #8 (7/16ths i.d.) lines to a Y block, then a fitting from block directly to Quadrajet. I was very concerned about volume more than pressure, what with the small bowl on a 207. I, too, set my pressure at 6 or 6.5 lbs. and never touched it again. I can say I never had any fuel problems.
