[BDR 699]

I just bought the Mass Flo kit and will be installing it this weekend. It came with an Accell pump (looks just like the Mallory, and uses the same repair kit part numbers). It also comes plumbed for 8AN only to the filter; from the filter to the rail (and beyond), it is plumbed for 6AN.

I bought fittings to upgrade to 8AN from the filter to the rail. Had to get them elsewhere, as Mass Flo was not willing to do any substitutions.

My engine builder (Keith Kraft small bolock 427) recommended 8AN to the rails, rather than 6AN. He also recommend the Mallory (Accell) fuel pumps much greater capacity than the Walbro. Chris at Mass Flo recommended the Walbro, with 6AN everywhere. I followed my engne builder's recommendation. I did not want any questions down the road if I was to have an issue.
