fuel hose at tank question

[Buusted Buick]

helping the old man bring his '87 back from sitting and we just went through the gas tank.
dropped, flushed, painted.
we replaced the sending unit and added a Walbro 340.
I didn't notice until after we had the tank back up that the replacement hose he picked up (from sending unit to fuel lines) is rated at 50 psi and 'Not for fuel injection'.
Did we goof?
Thanks for the help.

edit : this is for stock config, only upgrade in fuel system is the pump and a hotwire kit we installed. I've read many posts on here, and only one or two mentioned high pressure hose is necessary. I'm thinking we goofed...

Unfortunately, yes, need to replace those hoses.

Update: at a minimum the 3/8" feed line needs to be replaced with high pressure hose. The 1/4" return line should also be high pressure hose. While the 5/16" CCP vent hose can be regular fuel hose (low pressure).

As stated, hose should be replaced.
Make sure the host is rated "submergible" or SAE 30R10

These are the hoses on top of the tank.

You are correct!
No need for submersible rating.

You need at least 30R9 for the ones on the top of the tank. AKA ''rated for fuel injection''.


The last thing you want is the car to coast to the side of the road while spraying a fan of fuel on the exhaust system (bonus points if you pull over over grass).
