Fuel line to AN6?

[nicemd]

Anyone know what kind of adapter I need to connect my CSR fuel line to an AN-6 hose?

The solid tube OD is about 7.75mm.



Thanks

I, and others before me, have used a AN-6 to M14x1.5 Saginaw fitting from Earl's Performance Products - a proven solution.
Earl's part number is: 9894DBH

Not sure where you might find a brick-and-mortar retailer with one in stock, but you should be able to locate one online easily enough.

Thanks a lot!

I´ve bought a lot of stuff from earls online recently, and I find them excellent to deal with.
Pity the pipe isn´t 3/8, you could then use a -6 tube sleeve and nut with a double flare.

Which braid are you using? The pro-lit hose is excellent. The nylon braid doesn´t file through everything it touches like the stainless.

I'm still planning so I don't know yet but thanks for the tip re nylon coated hoses. As usual it started small but now the plan is a lp and hp pump setup with swirl pot and AN hoses everywhere.

All tips are most welcome!

Oh boy, you´re in for a big spend!
Being as you´re up for more suggestions, get yourself a hose assembly kit http://www.koultools.com/ANHoseAssemblyTools.html you can get them from Demon Tweaks, a bit pricey, but they really make getting the braided hose into the hose end nut a breeze!
I was using mine last night, and I´m so happy I splashed out on a kit. Remember to use a bit of assembly lube

Another thing I have found to be good, is a device I found in Liddell of all places, that turns my small angle grinder into a chop saw.
Fitted with a 1mm disc it cuts the hose perfectly. Wrap a bit of electrical tape around the hose before cutting, them blow it out with the air line from the opposite end after cutting. A bit of lube in the end of the Koul tool, twist and push, job done!

I thought I could get away quite cheap with eBay parts and a bit of creative thinking , but all the AN connector adds up and I have to see if I find the price acceptable in the end.

Anyway thanks for the tips.

Before spending money witrh Earls or Sppedflow look at the stuff this guy does. It is really good - I've plumbed my car with it - no issues.

He on;ly sells via eBay though - http://stores.ebay.co.uk/Torques-U-K?_trksid=p2047...

Anyone have an opinion about this teflon hose?

The ad doesn't mention anything about conductive core and static electricity.
Is that something I need to consider?

[TeflonT]

Teflon hose requires special fittings. Overall the cost is similar to steel braided.

Rubber hose can suffer degredation over time - accelerated by the thred to add ethanol into modern fuels. So Teflon is not affected as it is not rubber.

The most significnat difference between rubber an Teflon is that Teflon dramatically reduces the smel of fuel in cars which are stored. Probably a good thing.

After a bit of googeling it appears that some believe the flow speeds in fuel lines are too low to build up dangerously amounts of static electricity, while others think the opposite. I don't know what to believe but as the Caterham is a "well ventilated space" I might just as well go for classic braided hoses.

Edit:
If someone would like to calculate on it, here are some good information and examples:

I´d go for the nylon braid. The stainless braid is like a file on anything it touches.

Also buy the fittings from the same manufacturer as the hose. Then you can be sure they are made for each other.
