I've got a leak that keeps coming back and came across the repair joints and watched your video thanks. I'm just going to eliminate the connection and install one joint
I've watched a lot of videos very informative thank you
I have a bonneville with nylon fuel line and repaired it with a union but it is leaking so im going to have to put a new union on i guess. But good video and great info !
Thank you man. My 93 Buick has a leak just like that but right before the fuel filter. Just ordered this!!
did you only used the puh union only…………..? or did you used the new fuel line hose and cut it?
If they make those repair couplings in 90° , could have used two with straight pipe in between.
why u got 2 inline connectors on one pipe, u could of took the one on the engine spun it round to join the one on the inner wing.
Ps: your wire insulation to me; is a good idea
Thank you so much; brought/installed the connector kit and the nylon press fittings today because of your video; very helpful. I was afraid to “cut” my cars original part at first. Your vid gave me some courage. So far so good; no leakage.
These Dorman quick connect fittings look like a pretty good solution to a similar problem I have on my 96 Cadillac Deville.
Do you trust them for use on the high-pressure line feed line?
I need this
3/8s feed 5/16s return
Thanks for the demonstration, including the slight misstep. Keeping it real.
Steel on steel contact with anything in the engine bay even with a hand hacksaw can make small sparks. It would be safer to cut the line with snips.
On my 2001 Buick Lesabre I had a leak in 90 degree fitting. Under the back seat there is a fuse panel. 2 Fuel pump fuses are in there. I pulled those out and started car till it died. It helped relieve the fuel pressure and saved me getting fuel all over the place.
I use a heat gun to warm up the tubing . You can put it in shape you need to .
I like the connection grips, where can i purchase this,
Thanks for sharing info and video. Thinking of using one of these push on or it’s £150 part and 5hrs fiddly fitting. Checking data sheet 10bar pressure which is good but worried about the 60c heat as under the bonnet (hood) gets to 80c on a LR TDV6 diesel, how has it held up?
Use pex tubing cutters
Just checked the GM shop manual. Back 3/8 line is Feed. Front 5/16 is return.
