hey guys, i did a search and came up with nothing.anyway i am going to install a fuel injected 383 into my 67 vert and need to run completly new fuel lines.i know what size i need but how do i connect up the fuel lines to each other.i know i can't flare them like brake lines and i've seen the expensive flaring tool for fuel lines.they r going to be steel by the way.obviosly i need a supply and return.are there special fittings or something?(i.e. an fittings?)also i really don't want to spend $500 on just the fuel lines.can anyone give me some advice?thanks....

Why can't you flare them like brake lines? Brakes run a much higher pressure than your fuel line . . .

That's what I would do anyway, they sell male-to-male adapters in the auto parts store just for the purpose of connecting two flared tube ends together.

thats what someone had told me.i know that brakes run at higher pressure that was what i was going to originally do.thanks...

I'd use a "B nut and sleeve".

That way you can use hard line to wherever, and from there you can use rubber, braided or TFE hose to another hard point.

You dont need a special flair, and it uses standard steel or alloy tubing. It also uses a normal non-compressed flair to a 'tube sleeve/b-nut' to make the connection. Super simple and its SFI approved (not that you might need it) but its a solid way to connect lines that are under 3000 psi.

thanks chicane67,can i get that stuff at any auto parts store?

Uhm, good question.

You can get it through EARL'S, Aeroquip, Russel, Goodrich and one other in aluminum. You can get steel fittings from Swagelok, EARL's and Aeroquip, or your local industrial "Hose bulder".

You might even be-able to find some items at your local parts store's like NAPA and/or equivelent.

Do Dorman fittings come in here too??

I know one of the local parts houses has a 2' x 3' wall rack with little drawers just full of stuff that is neat to look through to find fittings to use.

I think it is NAPA??

If you still want to use the standard steel flared lines with the b nuts like the auto parts carries the fitting used to connect them together is called an "inverted flare" union, because the union is female at both ends with the flare fitting sealing surface inside the union. They'll know what you're asking for if they know their brass fittings. I've used these whenever I make my own double flared lines. by the way the tool is about $60 from Snap-On and about $35 from most auto parts stores for the double flare kit.

SY1,

Will he have the same hassle using a cheap flaring tool like has been tried for making double bend brakeline flares AND just doesn't work, but now making gaslines?? So should he buy/barrow a good tool??

I ask this b/c I went through this when I made my front brakelines for my pdqCBB setup recently and if it hadn't been for the goodness of a Parts Store Counterman, I woulda been screwed!!

I'm just trying ta hold the frustration factor to a minimum, that's all....

pdq,

I've only used my Snap-On set, so I couldn't say. I know at the shop we have a cheaper set that was purchased at a local parts store. However the couple times at work where lines needed to be made, I brought my Snap-on set in from home and used it, again because I'm comfortable with it. I've not broken any parts, but I can say you have to clamp down the line in the block pretty hard when flaring or it pushes the line down in the block and you don't have the dimension of the proper amount of tubing exposed to double flare. Once you figure out how tight to clamp down on the line it works well.

The price difference was only about $20 between the Snap-on and the local brand when I bought mine, so with the lifetime guarantee it was a no brainer for me to purchase the Snap-On set. It paid for itself on the first 68 Camaro I did a full resto on after buying the tool.

You have to be carefull about mixing and matching these parts. Most of the Earl's, Aeroquip, Russell, etc. parts are AN type 37* flare fittings. Everything that I have ever found in an auto parts store is SAE 45* flare. The two are not compatible and require different flaring tools.

Good point Carl. The AN flare fittings do require a different flaring tool as well to be used with the 37 degree standard. The auto stores will only carry the SAE 45 degree tools. Most aircraft tool suppliers or military tool suppliers should be able to set you up with the 37 degree flare tools for use with AN hardware.

Has anyone ever seen those Russel hard lines that require no flaring? They say they're a "crimp" design? Anyone use those? Think they're any good? If so, that might be a easy choice for your line plumbing.
