Rotoflow tanks...bunky or bullet proof?

[49dimes]

Speaking of tank leaks.... I pose a question to those that have been operating these water bottle style fuel tank / systems.

Any problems with the main cap keeping its seal nice and tight after the rigors of gas engine flight?

I find my self looking and checking for weeping at the neck of the bottle very often. Every thing seems fine but it's making me nervous thinking of a bunch of gas spilling in to my new bird. This is my "virgin" experience with these tanks. I have been a long time stopper tank operator.

No one ever has had a leak at the cap on these KUSA, SEACRAFT,PSP tank caps???

I keep asking the same thing. So far so good knock on wood! I only use a 2 line system with a "T" in the pickup line for fueling and de-fueling.

Kelly we been using them for sometime now, with no issues. I don't like the cheap colored fuel line, and have been replacing clunk line with tygon. I just installed one in my Sukhoi, an left the blue fuel line in, after adding the brass tube in middle. @emtp275 an I cut it short, because I knew it was gonna swell/grow, well it did. I get to pull it apart again, and redo clunk.

Need to use Viton on the clunk line, no swelling or cracking, you won't ever have to replace it again.

Thanks Donnie and @camss69 . As I had mentioned in my build thread the KUSA tank had a leak on the fill drain fitting itself.
I kept the "blue colored" tubing that came inside the tank and it seems that I need to replace it then. The yellow stuff you see in the pictures outside the tank is siliconized poly and I have been using it for 5 years now with no issues. I will re plumb the tank guts with that cuz I keep it on hand.

Never had any problems with leaking. Viton inside the tank, tygon outside.
