Is it SAE 30R10 Rating?? Need help please

[72Z/28]

I have an aeromotive stealth fuel tank installed on my 68 camaro and have recently experienced fuel pressure issues. Fuel pressure drops to zero once the engine is turned off. Also, while accelerating, the engine stalls and the fuel pump does not hold pressure at all. So I decided to drop the tank and pulled the fuel pump assembly. I noticed that the hose (5/16") connecting fuel pump to the outlet port has a crack in it.

I believe the cracked hose is the culprit causing fuel pressure loss. I have a brand new aeromotive fuel pump kit (part no 11540) which came with a 5/16" hose. Just wondering if the hose supplied in the kit is a submersible fuel hose ( SAE 30R10) rating as there is nothing printed on the hose.

Will appreciate your input guys
