I need to replace the rubber fuel line on my 88', and I've never done anything like it. Anyone here have any advice, tools, or tutorials they would recommend?
(don't have any pictures at the moment as the truck is dead at a friends house)

I understand I'll need SAE J30R7 fuel line? Should I replace any connectors at the same time I replace the line?
(Doing research as I type this up.)

Here are pictures of the immediate problem and the line in general:




I've got a spare fuel filter for the truck so might go ahead and replace that while I'm at it. But I'm not sure if theres something extra I need for the top connection (where it is currently NOT connected)?

So it appears I am missing a piece... Anyone know what that connector is called?

(Also if this is in the wrong subforum please let me know where it should be)

 

I would replace that line and not repair it
You should be able to find a good one at a junkyard
That said
You "can" use 50 psi rubber fuel injection hose
That would need to be replaced every few years and might crack and start the truck on fire in the interim
Big underhood heat is why they used the insulated nylon hoses, and later the stainless covered rubber ones

 

I have used SAE J30R9 hose instead which can handle 100 psi instead of 50..The SAE 30R7 is not the best hose to use for fuel injection. It will be fine for the return line however. I would NOT use worm clamps like that but actual fuel injection clamps instead, like these....

I'll see what I can get instead of the sae 30r7.
The worm clamps will go away when I replace the line. There was a small plastic fuel filter there that started leaking just in time for the emissions test so the mechanic replaced it with that join and clamps. The new line will be continuous through that area (though I'll keep the fuel clamps in mind incase I need them in the future).
My biggest unknown is still how to connect the line where its disconnected in this picture:

I haven't been able to find a name for this connector so it's been hard to find a replacement.

Thanks for the advice! Glad I asked before trying to put in the rubber line!

 

Here are a couple more options, including using a caulk gun and a brake line flaring tool, to press fittings in.

 

If you do buy replacement lines, make sure the quick disconnect fittings will work with your fuel filter.
I think the dimensions changed between the locking ring and the end of the nipple for 1990 and forward trucks.

 

The connector in post 4 is called a spring lock connector. Scroll down to it in this thread https://www.therangerstation.com/tec...nes/#gsc.tab=0

 

Yes! Thank you! Knowing what that's called is a game changer, it's been a pain trying to do my own research not knowing the right words for things. And that article is very informative, thanks!

 

Thanks to everyone who responded, I was finally able to get the spring lock connector firmly back in place with a little bit of help from a hammer... and have decided to stick with replacing the fuel filter and leave the line alone for the time being.
Time to move on to other problems!
