G&J in Ontario, Cali can sleeve SB lines so they dont rub anything raw. Also if you can find one of these adapters you should be set

All Sounds like alotta trouble when you can just get a firewall to rail stainless line. If you wrap it up you don't have to worry about it tearing anything up.

 

Since everyone has latched onto the compression fitting solution I'll just share an experience...When the Pro Formula Mazda car came out in '04 all of the engines were fitted with the earls 5/16 compression fitting to -6 for the OEM Mazda hard line coming off the fuel rails.....well my car leaked around this fitting(not nice) I then looked at two other cars and found the same fitting could be easily turned on the line...This led me to switch this to the metric equivalent made by Goodridge.....much tighter fit and no leaks...just my 2 cents.

 

Well, I got my flared lines back. Here are a couple of pics. I'll double check tomorrow that they're airtight, but they look really good if you ask me.

I'm still trying to figure out exactly where the adapter comes from in my pic above. They come on the engines I buy and they seem different than the fittings every one is showing. The one in my pic have a plastic insert of some sort and it doesn't look like a compression fitting.

 

Got the Goodridge part number handy?

The 5/16" Earls fitting I used cannot be "turned on the line" the hard line bends before anything moves.

However I'm always looking for a better soln.

Just FYI... the Earl's site says the compression fittings should only be used to 50 PSI...

It sounds like you guys aren't having any problems. If so, great, but just be careful.

I only used the compression fitting on my return line. Good info regarding the max pressure though...thanks.

If you're changing any fuel lines to aftermarket lines, use black nylon fuel lines SS lines are more expensive and poke your fingers up when installing the fittings. Buy this tool from koultools.com and it'll be alot easier install..

bump......def should be some better solutions by now huh?....and anybody have the part number to the goodridge fittings tat were mentioned earlier in post?

 

I know this is an old thread, but I have gotten some fittings that were custom made from Garfinkle that slip on the oem lines which are in fact 8mm metric and can be brazed on for a tight fit as per David G, but I happen to have a nice welder locally and he recommended I have him Tig Weld the fittings on!!! He did a great job!!!

 

Since this thread has been bumped already, I'll just add that I've been using the Earls 5/16 compression fittings since this thread was made, and I haven't had a problem with them yet. They're still tight and haven't leaked/sweated any fuel.

 

This is perfect information...I was just researching this as I am piecing together my fuel system upgrade.

So what are people using? I've read that Earls says those compression fittings are only good to 50psi, but then I saw an video done by an Earls vendor on them that says you could run well over 100psi...

I was going to go with just the tired and true method of using a high quality hose clamp over the AN hose on the stock line, but it just doesn't seem very clean to me.

 

If Earls made that fitting in SS I would be much more inclined to use them, I have seen compression fittings at work at pressures above 1000PSI, the fitting and the lines were SS though.. with those Earls fittings being aluminum I don't see them as trust worthy for medium to high pressures... (50-100PSI) I think the best solution is either the flaring, or welding the fitting on...

(I work in the Oil and Gas industry, the lines and fittings were used in the sensing portion of distribution stations for natural gas, cutting pressures from 1600PSI to a much more user friendly 79PSI)

I'm right here with ya bro. No issues with mine either.

Following up on my own post from years ago: I've been using the "clamp the AN hose to the stock hard line" method for years now with zero issues. It's the easiest solution, albeit not the prettiest.

 

Back from the dead. Has anyone had any issues with the Earl's Compression fittings yet?

 

Compression hard tube no. 5 to no. 6 AN or JIC fitting. Used em for years, never had a leak.

 

Nope. 5 years later.

Do you guys have links to your respective setups? I'm having trouble finding the right stuff.

 

I use the compression fitting on my ls3 swapped fd 60psi and never had one issue with it.

I ordered the Earl's -6 AN tube nuts and sleeves. We shall see how it works out.

I couldn't justify the compression fittings since Earl's says 50 psi max...

 

Swagelok

The proper way to do this is to use a quality, precision compression fitting that is harder material than the tube you are putting it onto.

I was familiar with the quality of Swagelok brand from my work on industrial machinery so this is what I used.

"-8M0-7-6" is a stainless 8mm tube compression fitting to 3/8" NPT Female thread and then you use a common aluminum 3/8" NPT Male to -6AN fitting from Jegs or Summit. Always use the stronger material for the female end to attain the highest pressure rating. This combination would be 4,500psi I think.

If you have to keep the assembly slender but you have some length you can use a "-8M0-6-6" stainless 8mm compression fitting to 3/8" compression fitting to a "-6-TA-1-6AN" stainless 3/8" tube to -6AN fitting.

I haven't found a metric one piece adapter for 8mm compression fitting to -6AN.

 

These right here? not bad!
