1977 Seville Fuel Hose Question

[1977Seville]

So today I replaced the hoses on my Seville. Then I noticed the label “not for fuel injection” so I asked the local parts store where I got the hose and the man who has been running it for 50 years said I had the right hose. He said that the old Seville injection system used standard fuel hose. I checked the malleability of the original hose marked with gm labels alongside the new hose and the malleability was the same. So I guess gm used regular hose? The vent hose was also original and it was much more bendable even after 41 years than what I replaced it with.

Big question is will it hold 40 psi fuel pressure?

Right, whether the Seville originally used fuel injection spec. hose or not, there is no reason not to use it now in my opinion.

Can't tell what hose you replaced, there are fuel hoses at the tank, around
the frame pump and filter, to the engine.  I would not chance 40psi on a
non rated hose.  Bruce Roe
