good thing it's not heat shrink tube. I hate these newer plastic fuel lines & special fittings. Reminds me of irrigation drip hoses for gardening and their "quick disconnects". Never thought such would be on vehicles for fuel delivery. I think I'd put that hose into a vise to heat it up. We just had to deal with this crap on a 2007 Dodge RAM 1500. I wonder if vehicles catching on fire have increased since these plastic hoses became the new standard? I did however once use thick wall clear vinyl hose from local hardware shop on my old '77 Dodge PU between the fuel line and it's mechanical engine driven fuel pump, and it lasted many years. It's advantage is allowed me to see if fuel was making it to the pump or not.It lasted more years than some rubber hoses with this newer ethanol gas now. I use some oil into each fillup of tank, and have hotter plugs on it (keeps fouling away) , which controls "ping" and not a problem since no catalytic convertor on that older truck.
Hi, I have a 2002 pt cruiser and my line broke off right at the base of the thermostat. How would I do this
very helpfull, thank you
Excellent tips. Thanks
Good info! I was thinking boiling line then a quick shot of wd40
Can these nylon hoses be used as brake lines too?
I won't recommend using nylon hoses for brakes. Brake hoses are a heavier material to handle pressure from the master cylinder.
Be careful..too much heat causes the line to collapse when pushing the fitting in.
Great video I agree with you I had a little luck when I did as the direction suggested to use boiling water.
Thank you !
thank you for sharing In my case, the line was coming out of the fuel tank so I could not use heat. Thankfully, Dorman recently designed an ingenious coupler that saved the day for me. Simply cut the line and attach the coupler to join the existing line with the new extension. The coupler acts like a lobster trap in some way, engaging on the outside of the line and gripping the line. See Dorman Nylon Fuel Line Press Fit Unions. In my case, 5/16" did the trick. Partr # 800-191.
scotty_rides thanks, i had found that part but everyone was trying to get me to use a blow dryer on the return line to the tank. I'm not trying to win a Darwin award
he needs a watch that is a lot longer than 30 seconds
You can all ways put a crimp clamp on it to
Thank you Sir
I tried this in my crown vic and the pressure just keeps blowing it out ughhh
Make sure the gas line is pushed all the way up on the connector and the line should be skin tight around the connector so that you can see the outline of the connector's barbs. You can also add small hose clamps to help keep the line on.
Where you order the part from
@Jack Schnitz hey how much was it
Esteban Rexach O'Reilly auto parts it's a barbed connector you can also start em in and grease and smack with heavy wide hammer and pressed in like a seal
I didn't order it, just purchased it at my local AutoZone store. You should be able to purchase it at any local auto parts store.
No, but it works better than what the Dorman instructions suggest.
You sound very much like john reilly. Shake it and bake it.
thank you is all i can say
with a piece of hose in hot cooking oil . I ran some test and the plastic hose from the gas tank become soft at 300F. pointless to use boiling water 212F. My heat gun on low will heat a a cooking thermometer to 350F. gasoline has a auto ignite temp of 495F. if I heat up a cotton ball soak with gas on low or high no auto ignition occurs just browning of the cotton edge but I am still nervous about that .. I wish they still use the good old rubber hose
Lol, It's possible I made a mistake and put the non-lubed end on. Believe me the lube end slides on much easier.
if you look at 2:10 then look at 3:54. It looks like he put the non-lubed end in.
what part of Louisiana you from
I don't live in Louisiana, I'm in Tennessee.
Is it safe to use Vaseline on fuel lines? I mean it is flammable
I know that vaaseline is flammable as you've noted. I saw firemen some in an oxygen rich environment and wow it burned intensely! Good luck. I just spit on the damn things, if it sizzles I'm outta there!
so is fuel? if it doesn't ignite the gasoline, I'm sure Vaseline will be alright. Lol.
Good question, the fuel pump wouldn't get hot enough to ignite Vaseline. Also it just a thin film, just enough to allow the tube to slide onto the fitting. However some oil based products can cause deterioration of rubber and plastic hoses and I'm not sure if Vaseline isn't one of them. The fuel lines on my van that connect to the fuel pump are some kind of hard black plastic and I used Vaseline to help slide them onto the fitting. So far after 3 years of driving it, I haven't had any leaks or fuel line problems.
Are you using a doman or standard size fuel line? If so, then just vaseline & a heat gun should work. Some hair dryers may not get hot enough.
hi. i have tried i cant tell you how many different ways to get the nylon tubing onto the quick disconnect and nothing works. ive tried boiling hair drying heat gunning you name it. any advice would be great!!
They were the same size pushed the skin off my thumb, I just got the whole system fuel line, fuel filter, fuel regulator line lowered the tank they were color-coded just snapped together in place $26 Raised the tank back up and was able to drive again
You were probably trying to put a 3/8 union into a 5/16 fuel line. You need to get the proper sized union to fit into the nylon line.
I tried I don't have the answer :^( There is a special tool which I don't want to buy for one time
i did the vaseline also but no go.
this was my plan also i love vaseline its like a super clean grease that i use in the garage just hope fuel wont ignite under car when i install the piece with both connectors to the fuel lines already cut under the car -thats the hard part its always easier standing in the shop doing most of the work than say in the cold on your back in the dirt with rust and crap falling in your eyes. Amen from all you backyard mechanics? PS try a high power hair dryer under car for safety sake especially if you dont have a heat gun
That my be possible, but I would first research if a heat gun could ignite gas fumes. Also make sure that line does not have a straight path opening to tank gas fumes. .
can I use a heat gun while the line is still in the car Connected to the tank,I don't wanna drop the fuel tank
Thanks Evan. I broke a fitting yesterday, went to Autozone and was still at a lose reading the Dorman stuff until I actually saw how you did it. This is the power of online home made videos. Great job!
I guess I gotta go buy a heat gun. I tried boiling water and it went half way up. I then used more force and it crimped my plastic line. I was thinking of using a heat gun and also a vice with wood around the tube? I will first try the heat gun with a small piece that I am working with. If successful, then on to the 3 foot section needing to be replaced.
if you don't have a heat gun, try using a hair dryer.
I just performed this repair.no lubricant.just used a hairdrier for 1:30 on the line and pushed barb all the way to the end.this video actually intimidated me,until being out of options had to go thru with this procedure
Hairdryer did not work for me. Maybe you have very strong hands.
Thanks for the info.... The petroleum jelly is what REALLY helped, heat gun alone wasn't cuttin it! Good idea.
This is a great way to do this!!!! This just saved me 2 hours or so of hassles. It is great folks like Evan that share their knowledge and experience and make the world a better and easier place to live in. This is a very clever way of doing this repair. We welcome more videos from you Evan. Any new ideas! also have also found that a pair of small visegrips can help lock the disconnect clamps in place to remove the line. Also they make a pair of pliers with a rounded grabbing end that are nearly perfect for grabbing those clips. 'The dorman line repair kit is about the same price online as at Autozone. This kit was $20 plus tax at an Oklahoma Autozone in late 2014. Thanks
Thanks Evan, I am going to try to do this also this weekend....
I'm doing this job this weekend. Thanks for the tip. I'm going to Harbor freight tomorrow to buy a heat gun. To be honest, I didn't know how I was going to apply boiling water, for 10 mins, to the section of fuel line that's attached to the fuel pump under the car. I thought of using a heat gun. Glad to see it works.Good Presentation. Thanx
