Fuel Log

October 28, 2015
This fuel log works well and adjusts nicely. I ordered it for the Holley ultra hp carb and it will not fit correctly. The fuel log hits on the secondary linkage requiring it to be ground down so you can tighten it up without contact.
Yes, I recommend this product.

Duel Feed fuel log

May 25, 2010
This fuel log is very good. Great color. Fits Great. Works like it should. The only problem is I had to grind down the second hex nut of the fuel bowl extension because it got caught on the fuel bowl screw and prohibited it from tightening down enough seal. After I ground the nut down it sealed perfect and works just like it should.
Pros:
  • Looks Great
  • Tight but perfect fit
  • No leaks
Yes, I recommend this product.

what size of o-rings are used on the ends that go into the center section? I have one of these and it started leaking out one end. I have checked all around at the parts houses and cannot find a correct o-ring. I believe that it is a 1/2 id x 3/4 od. everything that I can find is 1/2 id x 11/16 od and it fits loose and leaks. thanks

You may need to get O-rings from a large supply house such as McMaster Carr. They offer a much larger variety of sizes than a local parts store will. Sorry I do not offer the correct replacement O-rings.

The fuel log has O-rings that seal the ends and it provides a limited amount of adjustment for different spacings from fuel bowl inlet to fuel bowl inlet.
