Hard fuel lines
I am in the process of changing a few things while I have the bed off my 1990 long box 302 manual transmission 4wd f150..
I have changed all the brake lines , put in the new exhaust.
but I do not know much about these hard plastic what appear to be factory fuel lines
can I just buy rubber fuel hose and clamp the ends …seems a bit magiver to me .
id like to do it right and not have to do it again for another 20 years.
I mean how much pressure is actually in these lines is that why they are hard?
thanks in advance Roy

The factory plastic fuel lines seem pretty robust. Ford did a good job for securing them to prevent them from getting chaffed or damaged. If they're not leaking, I wouldnt touch them. Yes, you could replace them with rubber EFI rated fuel line of the same inside diameter, but you'll have to resecure them to prevent them from being damaged.
these lines see a maximum of 45psi. I think the earlier 300ci engines run them at 60psi.

If you want all hard stainless lines checkout inlinetube.com
They used to have an ad in the 4wheeler magazines $99 for a complete set of pre-bent stainless brake lines for some vehicles.

Thankyou …I will leave them. I was under the truck a lot today and they all seem ..what’s the word …very serviceable.
one of the 90 degree fittings on the end of one line was broken..I’m presuming I can replace that and the little white clips that lock it all together.
thanks

Yes. There are nylon hose end repair kits. The lines are two different sizes and so are the retaining clips. One hose should have had a white retaining clip and the other clip should be black. Any parts store should have them.
