Konish Posted August 1, 2010 Share Posted August 1, 2010 Fellas, Installing a Holley Red in the near future and before I order the wrong size fittings I was wondering what size fuel lines exit the fuel tank? Also, I'm thinking about 2 90* fittings for the input and output sides just from other pics I've seen of similar installs...any other suggestions?

Tony D Posted August 1, 2010 Share Posted August 1, 2010 90 degree fittings look nice in photos, but really you want at least 12 diameters of straight fuel line into and out of the pump for best flow properties. On the inlet side at least, discharge is a bit more forgiving but a straight fitting and slow curve on a discharge flexible line will flow better and result in less pressure drop.
