AN/Thread size/type Hotwire Fuel Rail 2 fuel feed hose?

Cappucino-kid · Post by **Cappucino-kid** » Thu Feb 02, 2012 6:02 pm

Hi All, spent the best part of today trying to find a suitable after market male style connector to use on the feed inlet hose side of the fuel rail, so far without success, does anyone have any suggestions or know what size/style I should be looking for?
If I remember correctly (I don't have the original fuel hose) the original OEM hose has a rubber 'o' ring seal and a rotating style male fitting, no idea of the thread size, and have no way of measuring the female thread which is still attached to the fuel rail ......

Any help appreciated as I'm all googled out!

Thanks a lot

Mark

Can you get hold of a thread guage?
This will help identify what you have.
If you can do this and let me have the info i may well be able to help you out with an AN fitting.

Thread guages readily available at most good tools stores.

cheers

P - I'm not sure I'd get a thread gauge inside the union?
I can tell you the union is 9/16 across flats, and the thread looks quite fine?

Post a picture of what you have.

Or just cut it off and weld on a -6 fitting. Job done lol

It could be a proprietary fitting if it has a fine thread.
It could be a NPT thread.
AN type threads are UNC specification.

Maybe this will help.... http://www.gre6.com/ansize

As Steve says it may be best to to cut and weld or send me the rail and I will get a fitting for you.
cheers

Hi All

I've hopefully sourced an original piece of fuel line with the fitting on, will keep you posted over the next couple of weeks (I won't get it for a couple of weeks now).
Thanks to all who have contributed so far, it's really appreciated.

Regards

Hi, If you pop down to your local hydraulic/pneu fitting shop and find a male 6mm hosetail to 1/4 steel standpipe fitting and unscrew the outer
hex, the inner thread will fit the fuel rail.
I did exactly that when fitting my 4.2

we made this from a -6 to m10 (i think) adaptor and turned the m10 part down and tapped the correct thread for the fuel rail onto it, hotwire to -6 adaptor

Great tips guys thanks - I should have an original lentgh of fuel pipe with the correct end on winging it's way to me as I type, I did find these the other day, they do look similar but don't know for sure (they are about half way down the page the one's with the 'o' rings)

spent quite a bit of time looking on this site, they appear to have some good stuff - anyone had any experience with these people/stuff was thinking of getting some of their fuel line not sure which one?

Regards

I guess they are the same as the one you used Coops?

Just phone them and speak to them. Ive used loads of their stuff and never had any problems.

But do you need to go do the expense of fancy fuel lines etc ?

Not neccassarily wanting fancy stuff Stevie - just good quality.

More than likely you'll be needing 8mm fuel line. I dont actually think Earls etc do that size, as typically they do the imperial sizes for their AN fittings.

Which are typically 3/8, 1/2" etc 5/16! which would be close to 8mm would be an oddball.

But depends what you actually need. Sytec seem to offer some decent efi rated hose in 8mm which would be fine for normal fitment.

Again, plan the payout, decide what hose sizes you need and where, and what sort of fixing methods to any hardline pipework etc.

I'm having to make up the whole fuel line - I did ask on another post what the general feeling was on using all rubber fuel line or a combination of metal/rubber?
Take away costs and tooling required for making up metal lines is there any advantage in using them - manufacturers seemed to prefer it before plastic lines came in, but that could just be an assembly issue?

I used a rather crude method of measuring the internal bore of the fuel rail with a drill bit, I made it @5.5mm on the feed, and slightly smaller 5(?)mm on the return, not sure what that equates to?
