Fuel line question

[Catterman]

On my 1990 B2, the end of the fuel line doesn't seem right. I contacted the previous owner and he says that it broke on him out on the trail, he had to cut the access hole in the back, and then used zip ties to keep it on. It seems very weak and I think it is the cause of my truck taking longer to crank before it will start. I took it to O'Reilys and they have "fuel line repair kits", but I need to make sure I get the right size.

So, Anyone know what size the fuel line is that I should get? And how hard is it to fix this?

Thanks!

Can a modarator move this into the 2.9V6 section for me?

Thank you very much!
