Fuel hose used for transmission

[Blazin]

Not sure about all ATF, but the old standby dexron etc. are derived from peanut oil.

when i did mine lucky i was at dads, it was the rear seal leaking till i noticed fluid all under the motor. he then gave me a flaring tool i just looked at him with a confused look. so he told me to flare the ends so the line wont slip off cause the clamps aint enough

how much pressure is inside the transmission lines?

[Irish_Alley]

i dont believe that the ATF will "eat" the fuel line, but the plain jane fuel line has a lower pressure capacity than the trans cooler line. i try my best to use the correct trans cooler line or when possible i prefer power steering return line. its is the strongest. and i ALWAYS double clamp rubber lines...it scares me to be at the big end of the track at 113+ and having a fluid leak!!!

iirc it breaks down kinda like this...
fuel line is rated for 10 or so PSI
trans cooler is rated for 25 or so PSI
F.I. line is rated for 70 or so PSI

i did some research on it years ago when i was slinging parts for a living.

going by that i would say lower than 25

[chevymanrob]

if i was given correct info its in the 15 PSI range typically.

makes sense, they wouldnt make a hose right at the limit of the fluid its trying to hold

problem solved, found a shop that had it by the foot.
