Fuel Line Fitting

[GasManLS7]

Anyone know which fitting I need to connect a braided fuel line in the engine bay to the underbody fuel lines?

These are the push fit connector ends underbody:

Need an AN6 connector that will connect to the Braided Line and then push fit over those

Id personally renew the lot straight back to the tank in an6 pipe and use one of these on the sender. It might fit the connectors on the plastic pipes too but unsure

Careful with those AN fittings, it can be easy to accidentally select something too small and some of the cheaper fittings can have less ID than you expect.

Torques/motamec an fittings are always pretty decent from experience. Avoid any unbranded chinese shite though.

Same with the fuel line itself! I nearly set my RS Turbo on fire because I had bought Chinese braided fuel line, the rubber inside perished with a few months and I had fuel pouring out of everywhere.

Any advice on good fuel line supplier?

Get Aramid hose as it's ethanol compatible and won't leave you having to rip it all out in future.

Mr Injector: 7.3mm ID 9.3mm ID 11.5mm ID

Car builder solutions offer 5 different sizes

Also Viton O-rings for injectors if you're doing those.

The next car I do the fuel system on I'm going to spend my time planning it well and just go with Aeroquip everything, fuel line, fittings etc. It will be several hundred quid more expensive than alternatives but ultimately I want to trust everything fully.

I don't really know enough to trust myself choosing alternative suppliers. The Mr Injector hose suggested above for example is probably 100% fine but in my head I would be wondering if it was just rebranded low quality stuff so knowing myself I would then spend an eternity obsessing over it... while just going with Aeroquip to begin with I would be fairly relaxed. I like their push fit stuff too.

Injectors all new with new seals.

Was gunna use PTFE but will look at Aramid

 

[Brigsy]

Use ptfe/nylon overbraided an line. Its hard plastic with overbraid and never fails. Basically more or less same as oem with braid. Torques brand again is fine. And remember to order the correct fittings to suit.

Recommend using the nylon finish or the stainless braid with the clear rubber cover, to save taking the paint off everything.

Avoid rubber stainless overbraid, as above cant monitor condition.

Perfect cheers mate

If its your first time using the ptfe then buy a set of large electric cable shears to cut it. Makes life very easy when fitting.

Also avoid rubber like the plague if running inside the car. It omits fuel fumes and stinks

 

[GasManLS7]

Was gunna tape it, hold it in the vice then use a cutting disc?

 

[Brigsy]

Masking tape and 1mm cuting disc is ok. The shears are epic though if doing loads of cuts as gives a very clean sharp cut where grinder gets a little bit of an edge on it, and you can cut them in situ with the shears.

I use these ones paid about £15 a few year back
