    honestly, i'm going on what i remember them looking like from last spring.. :o they might may very well be 1/4... actually now that i think about it, 3/8's is pretty big compared to what i remember putting in when i went with Endura fittings and #6...

    thought i had a link to a list.. hmmmm, wait, here it is... http://www.tciauto.com/tech_info/cooler_fittings.htm

    looks like i was wrong, t400 and 700 are the same at 1/4 and it says 350 is 1/8.. boy that seems small for a tranny line...

    5/16" tubing is for trannies

    3/8 was for 4 bbl carb fuel feed

    5/16" also was for 2bbl carb fuel feed line

    3/16" is front brake lines and rear axle tube lines-= after the rear hose split block

    1/4" for rear frame line all way from the rear brake m/c port

    just to let anyone know that's thinking about a braided line swap. i ordered the 1/8" pipe thread fittings for my th350. no worky :mad: too small! must be 1/4" TCI's info isn't complete :dunno: the tranny i have is the standard th350 to 203 nothing exotic.

    What type of plumbing/hose would one ask for if running soft transmisson lines ?

    I know the high temp rubber stuff is not good because of fire risk, but could I run all the special braided hose instead of my poorly routed metal line ?

    iirc NHRA regs are less than 24" of rubber line on vehicle? the more rubber line the more risk of leaks/fire. factory steel lines work fine for 99% of rigs, braided lines for trannys may be overkill :dunno: 6an line should be fine for trans lines. i was most concerned about chassis flex and fatigue with steel lines as well as aftermarket cooler options so that's what made me decide on an stuff :D
