Ok, I'm a backyard hack and haven't had to mess with fuel lines. Til now.
New tank in my truck with a new hanger assembly etc....now I have to reconnect the high pressure line.
But - the rusted fitting here doesn't turn! Is it supposed to??? It was so gone when I disassembled, I took the other side off. Now I have to mate the new to the old....don't tell me i have to remove the whole short section here, back 6" or so? Cuz THAT fitting isn't too good either, lol. I hope this isn't one of those 'special order from Toyota wait 7 days' things, ugh...
Okay, like any good hack I grabbed the silver crimp and spun the nut, it rotates now. I just hope I didn't ruin something internal to make it leak.
Only one way to find out!
Do ya put pipe dope on a connection like this? I do for plumbing, don't know what's normal for fuel...
Going to be hard to put that line on if the fitting won`t move
Yes it is one of those order from Toyota .
It would have been so much easier to have put a tank in the bed.
Worse case run a section of Fuel Injection Hose ( @ $7.00 a foot) with fuel injection clamps from the fuel pump bracket high pressure line to the good steel line .
... Do ya put pipe dope on a connection like this? I do for plumbing, don't know what's normal for fuel...
NO. It has nothing to do with fuel; pipe dope is used only on tapered threads (like plain ole water pipe), which seal by distorting the threads.
Flare fittings seal by pressing the flared tubing to the seat in the fitting. The (straight) threads provide the mechanical force, but have nothing else to do with the seal.
Think of a garden hose; it seals by the rubber ring, not by the threads. You'd never use pipe dope (or teflon tape) on a washing machine connection, would you?
Thanks guys! I did get it turning, and it *seems* ok. I'll be connecting it up in a day or 2 weather depending and will know if it leaks then. Nice rundown, Scope...I see now. So, if the flare in there is ok, and the tubing behind it, it should be ok. should...
Awesome tip, Wyoming! That's what I was looking for, if the old fitting is toast. Need a quick fix if something goes wrong (you have winter there, too). I'm going to get some injector hose just to have, it seems like a good idea.
Right, that's part of why I'm just trying to put it back where it goes, and will cover it with cheep DIY plywood "bed", if it all works. Aftermarket tank sits a bit lower than stock, tho, so (today) when I get the shackles in and lower the truck back down, I'll know if the driveshaft will hit it! If so, need plan B. Right now axles is on stands and the bed is also held up with blocks, so can't really tell if it'll clear.
So, it's cool to just run a couple feet of that injector hose to splice into the high pressure line, no BS? No need for flares or anything? Just the tubing cutter and go? I haven't worked with it before. But like I said, can do basic plumbing. The thought makes me cringe a little, 30psi and all that, just a clamp or 2 with no flare? But I'm going to get some today just in case. As with all 25 yr old things, one part of that line WILL go eventually!
I live 15 miles 'from town', if you know what I mean. Gotta plan ahead.
Thanks again, WY...talked to the guy at NAPA, got some line and clamps...he assured me it is just that simple. I way overcomplicate things sometimes when they're 'undone' before.
Let the truck down this afternoon, DIY shackles are holding fine and the tank doesn't hit anything!!! Lines, gas and hopefully ignition soon! We'll probably have plow-able snow here in 2 weeks.
