i ask because Rotary's are far more affordable than tangerine's. http://www.914world.com/bbs2/index.php?showtopic=110158 http://www.tangerineracing.com/stainlessfuellines.htm |

I'm running Robert's smaller set w/ a NA Suby6. No problem. Can't speak to the Turbo's w/ larger injectors but I don't think it would be greater than a 9mm line shooting gas at 60psi.

Go to your local Suby dealer and ask the parts guy what his stock lines are and make purchases accordingly. (IMG:style_emoticons/default/idea.gif)

she would never tell me if it did (IMG:style_emoticons/default/smile.gif) whew (IMG:style_emoticons/default/biggrin.gif)
she always says "good things come in small packages" you think she is talking about my .... $86 vs $149 i'd need a compelling reason to spend $60 extra bucks. though matching fuel line size to the fuel lines on a suby engine might do it, vs buying reducers to overcome the size difference ?? |

QUOTE(jimkelly @ Oct 5 2015, 09:56 PM)  $86 vs $149 (IMG:style_emoticons/default/WTF.gif) You need to compare apples to apples. My regular 2 piece sets are $99 I don't recommend the Suby set to anyone, and I only sell them to people who insist, or have a high horsepower V8 installed. |

10 feet of 9mm ID tubing flowing 60F gasoline at 1 gpm has a pressure loss of about 0.5 psi.
Throw in 4 x 90 degree bends and it goes up to 1 psi. Draw your own conclusions.... |
