Fuel Line Help

[brads911sc]

Can someone tell me exactly what size this is?

It is the fitting that connects from the accumulator to the hard fuel line... I want to buy the Male-Male adaptor so I can connect a -6 AN SS fuel line to the existing female hard line...

Attached is the fitting end Im needing to replace.

Thanks

Here is a pic of the line it connects to...

[RoninLB]

is this the line that connects to the tunnel line and is connected underneath the cabin?

[brads911sc]

this ends right near the fuel filter in the engine bay and yes runs to the tunnel...

I'm not sure what size it is, but here's a source: http://97.74.103.94/files/metric.pdf

You have what some call a Male bullet connector and it is M16 x 1.5.

I have a similar adapter fitting made up for 911SC fuel lines when converting to EFI.

It is shown at the lower left of this photo..........



However the one I stock is Metric threads on both ends.

I could ask my machinist friend to make one for -06. Making only (1) would be expensive, but if a few others need something like this it would certainly cost less per fitting.

We also have the Female version of this in case anyone needs one.......



Its a M16 Female bullet fitting designed to be crimped on CIS or EFI hose. We use this to make a hose substitute for your hard line from the tunnel.

Thats great. You can easily buy Metric to AN from Earl, Russell.. they all make them... All you need is a Female Metric to Male AN.

What is missing on the ones from Earl/ Russel is your Bullet Style end. All they seem to make are AN to Metric that are the O-ring end on the metric end like this one...



What is your price for the Adaptor shown in your pic.. I can make that work... Ill take two... You can PM me.

Thanks!

Brad,

Shown below is the fuel line that goes to the FA from the fuel supply line (metal). Both male and female connections are 14 mm x 1.5 pitch. However, there are some late SC's that might have the bigger fitting at the supply line @ 16 mm x 1.5. You can check the size by measuring the OD of the threaded section of the fitting.


Or if the flat section of the male fitting is about 11 mm or 7/16" (use open wrench), then it is a 14 mm x 1.5. The new fuel lines (superseeded the earlier molels) are available @ 16 mm x 1.5. Why are you replacing it to AN fitting?

The reason I am changing them is that I have completely removed the CIS components... for an EFI ITB conversion. My fuel rails, fuel pressure regulator all use AN fittings..

I have several choices on the fuel lines (supply and return).


On the supply side,

1. I could keep the accumulator / filter setup and use an Metric to AN fitting at the top of the filter that would go to my fuel rail... (I already have this)

or

2. I can toss out the accumulator and connect directly to the hard fuel line with a Bullet adaptor like Len sells that will connect directly to the metric inlet on the filter and then a Metric to AN at the filter outlet that will connect to the fuel rail... Basically throw out the accumulator and all those lines and associated hoses...

or

The third option is to dump those hard fuel lines completely and do something from the connectors at the tunnel (also something len sells). Still have the filter issue with this option.

What is better?


On the return side,

Its more complicated because the CIS connects diretly to this and so by dumping the CIS you by default dump a way to connect to the return line from the fuel regulator.

So I need an adaptor that will allow me to connect the fuel hard line to the fuel regulator.

As above I can dump the hard fuel lines completely and do something from the connectors at the tunnel.

Have you considered having it machine re-crimpped to a desired length of hose? I did that for my friend and 2 years later still going strong with no leaks. Of course if it is not damaged. My 2 cents

[boyt911sc]

Brad,

You have several options you could do and it's a matter of choice. Just bear in mind that if you have to delete the FA, you have to plug the drain line from the bottom of the FA going to the main fuel return line. If your EFI does not need a fuel accumulator, then discard it.

All you need is 14mm x 14 mm male adapter to connect the supply line to the fuel filter plus the plug to seal the FA drain line. I have several extra adapters you could have. I think you could actually hook up the delivery line directly to the fuel filter without any adapter. PM me if you need one.

Tony

[brads911sc]

That brings up another question... PMO never mentioned the Acumulator... one way or the other... Just assumed I didnt need it...

The inlet on the stock fuel filter and the outlet on the hard fuel line are both female. I think at the least I need a male / male adaptor. Will a 14-14 adaptor take into account the bullet /fitted end of the current hose?

One other factor in hooking it up direct is mounting it so there is no stress on that hard line. In some ways a short hose from the hard line to filter inlet so the filter could be mounted in the stock location would be ideal.

Why not simplify things and make up a metric supply hose directly from the tunnel to the Filter without adapters?

Then from the Filter make up a hose w Metric at the filter and -6 AN at the Fuel rail or Regulator.

I have never done this combination, but I think it would work. All my conversions have been Metric to keep things as simple & original appearing as possible.

When did a "flare fitting" become a "male bullet connector"?

[brads911sc]

I agree that this could be the most simple setup and the one with the least number of adaptors which is a good thing. I already have the adaptor to come off the top of the stock filter to the AN hose that will supply the fuel rail. All I need is a metric hose to come off either the hard line at the tunnel or the hard line in the engine bay that will connect directly to the inlet on the filter.

On the return line, I could do the same. I need a new line from either the hard line at the tunnel or the hard line in the engine bay. Then all i need is an adaptor from the new return line to the AN fitting pressure regularor.

I thought that too... There is a JIC/SEA thread fitting that looks similar... Its basically a 37 degree flair. There is also a 45 degree flair that is basically an AN fitting with Different threads.. There is also a 30 degree JIS. The JIC 37 degree has the same threads as the AN. If you buy the wrong one... it will leak because the flair angle is off.. The threads on the end of mine does match the AN, so the JIC 37 degree is probably what I have but there are subtile differences in these things. I didnt want to buy the wrong one and spend twice as much in the long run doing and re-doing... All these (30, 37, and 45 (non -AN)) would be condered Flare fittings. That is why I asked what exactly is it that Porsche used... Go figure...

The pic below is a 37 degree JIC.

Brad,

Right now you probably have all the fittings you need to run your engine. You could retrieve the old metric fittings from your old hoses and have it crimped by your local hydraulic shop using fuel injection type fuel hoses. Regular fuel hoses will work well in a carburated system but will not last that long in a FI system because of the higher fuel pressure. Since your rails have AN connections, this is where you would need the conversion fitting.

Just make sure that the fittings don't leak fuel and you'll be alright. You could mix and match the fittings, the secret is to prevent fuel leak/s and provide a long lasting fuel hoses connections.

brads911sc-

I would like to see what works as well. I make up Metric hose assys for 944s and Carrera 3.2s........



These assys carry a lifetime replacement warranty. Any leaks, send them back for a replacement.

If we (you or I or another Pelican) can come up with the correct combination of Metric & AN fittings, I will crimp the hose assys for you for N/C.

You may supply/send the fittings & hose cut to the right length. I will assemble the hose.

The only caveat is that I will NOT guarantee/warranty any materials you provide.

This is a one time offer. Call it a little thank you to all the Pelicans who help me out with questions I have.

NineOhOne-

If you look carefully, you will see its like a "Reverse Flare" compared to the -06 JIC 37deg flare adapter as above.

The DIN standard calls for a inverted 60 deg cone on the Male fitting...........



And a ball nose on the female fitting.....

Great offer. let me do some more research...

Thanks
