Can't get high pressure rail line to stop leaking

Probably one of the easiest replacement item. No cruah washer as others have said. I would so buy a OE filter. I purchased one from rockauto and decided not to use it because it came with washers.

 

I need a contact tip for my welder??or wire or shielding gas.

 

i had good luck with Wix then I stocked up a few years ago.

I have a few of the Toyota ones on the shelf yet.

 

Looks as simple as a brake line fitting?

 

Just a larger line!

 

Wix is (or was) the OEM manufacturer for fuel filters on the first gens.

 

Can I ask a side bar question?

I know the fuel line flare nuts are 14mm.

What are the other size flare nuts on a first gen? I have a Gearwrench flare line wrench set from 15 or 20 years ago but would want to severely upgrade. I’m thinking Snap On but do not want or need to buy a full set.

I’d just buy the one or two wrench sizes out first gens use.

 

Don't know the size needed but you should be able to purchase individual flare line wrenches from Snap-On. No need to buy a set unless that's what you want. At least you could do that in years past....... The Gearwrench set that you already have might also work just fine. Many of the line fittings remain the same today from 20 years ago or more.

 

Get underneath and measure your brake lines at the rear axle, spindles, etc.

 

Side Bar Answer

I have this set of flare nut wrenches, and they've been great. Haven't needed anything else for all the work I've done.

Also, there's a nice thread over here of all the various sizes/wrenches/sockets needed: Complete list of tools, sockets and wrenches for 1st Gen Tacoma | Tacoma World

 

Pretty sure that’s the same Gearwrench set I have. It’s done me fine over the past couple of decades. Figured I could upgrade.

And I have that thread/post bookmarked. And the shared doc.

But on the doc it says the only metric flare nut size is 10mm (brake line). But the fuel line is 14mm. So I didn’t know if there were missing other sizes.

EDIT: the OneDrive file is up to date. The images you provided are not up to date.

 

If you already have a metric set of line wrenches, no need to upgrade really.

Just a few months ago I changed the brake lines on my Land Cruiser, those flare nuts were so badly seized. But it wasn't an issue with my old line wrench set that I've had for over 15 years.

 

Admittedly I’ve been watching too many Project Farm videos.

 

Never seen it, but just wanted to throw in as much as I like nice tools...if you have a set that works, why not keep using them and upgrade something else like the TV in the garage or something?

My line wrenches are an old AF Craftsman set.

 

10mm and 14mm should cover it though 19mm never hurts

My Snap On set is from the seventies still going strong.

Having extra 10mm or 14mm line wrenche never hurts many hydraulic Hoses over the years.

 

Yeah I've monkeyed with brake lines forever, never had a problem...

But those damn fuel lines are a completely different story.

First problem is if the tube end gets bent a little on the end and it doent seat square...
the tendency is then to over tighten it to stop it from leaking and then you damage the lip of the double flare....
so has to be complete straight in that last half inch or so......
Ive got some pics somewhere, I'll try and find them.

Next problem I've seen is sometimes those threads are sketchy on first or two thread or two...
the larger diameter makes it easy to jump a thread and cross thread right off the start.
And then its a pain in the ass to get past that....wont correct itself....have to baby set it through.
I've had to get a needle file and clean the threads on the nut....and thread chase the receiver.

If you damage the lip of that double flare from those previous two moves, then you may be screwed....
it is really hard to reflare old metal of any kind......
And the oem replace hoses are just shy of $200...


I've had so much problems I never break those lines......always find somewhere else.
Always break the banjo's or something else......
but with the filter, you dont have a choice.



When I do have to break one of the those lines.....I use these that are made for 220 psi ac systems.....when I reassemble...
they've been an enormous help.
