Is it supposed to be so hard to get fuel line inserted into these fittings? (The red end) I'm pretty sure I got the right sizes. It's super hard to get non-braided fuel line to slip inside this fitting, let alone braided!
Some of the difficulty I had in the past was based on lack of a clean cut. We used to use a hacksaw (>30 yrs ago). We started taping it very tightly with duct tape and used a very thin cut off wheel to minimize the splintering. We were using aircraft quality stainless braided hoses on our race boats.
One more question. Once the hose is inserted fully into this type of fitting, that's it right? I mean, there's no where for a hose clamp, so it must be I guess ... Insert it fully and it will hold?
It goes together in two stages. First the collar is screwed onto the hose then the fitting is screwed into the collar. As said some silicone spray helps. Also make sure the hose is flushed of all particles from assembly before installing.
If youre taliking about the pipe threads, we used to tape ours but it wasn't pretty. I think there's also a liquid thread sealant you could use now but I'm out of my element. My experience is long past.
I use teflon tape on all pipe fittings. It's pretty easy to trim off any that remains visible with a sharp utility knife if it bothers you. I can't say it's necessary in all cases but it sure doesn't hurt.
AN or flare fittings do not need any type of sealer. Pipe threads should have some. If any stray piece gets in a fuel line it can cause the needle valve not to seat. Teflon tape is for non automotive plumbing, Teflon sealer is used on fittings and bolts into water or oil passages. Teflon tape on electrical sensors can cause the gauge to not read correctly by insulating the threads from grounding properly.
Pipe threads and bolts into oil or water are all that will need to be sealed. I use this on the pipe threads in the fuel pump fittings and on bolts where needed.
Sounds like you've got it figured out, but I will add one more tip. Before you screw it together, make a mark on the hose with a sharpie where it starts to go into the fitting. That way if it starts to push out when you are putting it together, you can catch it, and start over. Hope this makes sense.
Yep! Are these fittings metric or something? Seemed like a 3/4 wrench did the job but fit sloppy. It's a driver, so not worried about scratches, but just curious. Bo
AN wrenches are definately worth the money, most people can get away with only a -6 and -8. Aeroquip sells a vice insert FCM3661 which makes life much easier.
Back at it. This is as far as I feel comfortable going on the new fitting. This is where I snapped it off last time. This time I used anti seize (cant see it, wiped it away.
I have to believe this would be Ok?That fitting is inside the hose a long way, and it only holds 8 psi. Why does it go in so hard? Will this be alright?
Are you lubricating the fitting and the ID of the hose? The ones I use have the same length thread.
