HNTR Posted December 19, 2012 Share Posted December 19, 2012 (edited) what size braided lines would I use for fuel lines from the fuel cell to the pump on a pro mod engine. What size fuel lines would I use going to the intake?? Also, what size fittings would be used with those lines and would they be regular or compression, or would you put the two fittings together??

HNTR Posted December 19, 2012 Author Share Posted December 19, 2012 1/25 scale Quote Link to comment Share on other sites More sharing options...
wisdonm Posted December 19, 2012 Share Posted December 19, 2012 (edited) In 1/25, 1mm roughly equals 1 inch in 1:1. Also 1mm = 0.040" (0,03937"). Therefore, a 1/2 inch line = .5mm or 0.20". A fitting that needs a 1 inch wrench would be 1mm or 0.04". Edited December 19, 2012 by wisdonm Quote Link to comment Share on other sites More sharing options...
HNTR Posted December 19, 2012 Author Share Posted December 19, 2012 So what size lines are used on the 1:1? Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted December 20, 2012 Share Posted December 20, 2012 Probably AN -8 or larger. Everything fuel in that photo up to the barrel valve appears to be -8. A -8 AN line is approximately 1/2" ID. From the barrel valve to the nozzles appears to be -6. Available Hose Sizes -2 -3 -4 -5 -6 -8 -10 -12 -16 -20 Hose Size is the measurement of the Inner Diameter of the hose measured in units of 1/16th of an inch. Examples: a -2 hose has an I.D. of 1/8" [306 only] a -3 hose has an I.D. of 3/16" a -4 hose has an I.D. of 1/4" a -5 hose has an I.D. of 5/16" a -6 hose has an I.D. of 3/8" a -8 hose has an I.D. of 1/2" a -10 hose has an I.D. of 5/8" a -12 hose has an I.D. of 3/4" a -16 hose has an I.D. of 1" a -20 hose has an I.D. of 1 1/4" Aircraft-style braided hose uses specific fittings that match the hose being used. You use AN-8 fittings with AN-8 hose. The couplings are not standard 'compression' style; they have a specific 37degree flare and MUST be used with matched components. You can get 1:1 outside dimensions for the fittings from sites like Earl's Supply, Aeroquip, or Russell's. Or you can buy some of the excellent aftermarket ones, in scale.
