Fuel line connections and Filter location...

[Eternal]

Hello everyone!

Have been running my fuel lines today and all has gone well so far! But i have two.. no three questions....

1) How do you guys go about connecting 8mm copper hard line to 8mm flex lines do you just use clips to hold the tube on the pipe? Was unsure if i should put some clever type of connection on there as its fuel injection rather than carbs.

2) Also anyone know any reason why i should not put my fuel filter in the top drivers side corner of my gearbox tunnel? See pic below.

3) Do guy guys think that this type of clip will be ok? also seeing that the fuel lines are P clipped nothing will be moving around. http://www.ebay.co.uk/itm/Universal-FSE-Sytec-Motorsport-Fuel-Injection-Filter-8mm-/121020752235?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item1c2d66216b

Will be going down the garage tomorrow afternoon so any replies by then would be fantastic!

Bump.

Oh also bought some 8mm copper olives to solder onto the ends to give a good seal so that should be fine re the tube on pipe.

I just flared the ends of my pipe. i bought a flaring tool on ebay with about 5 seconds to go and when it arrived I realised it was metric. At least it came in useful for the fuel pipes!!

I also put a slight flare / bead on my copper fuel lines, then popped on fuel safe rubber hose and a jubilee clip. Still on the car and no leaks!

That's what I did, too. 8mm convex flare and hose clamps. Works fine.

As for the holder clips, if you pad them with something rubbery and clamp closed them with zip ties, they should hold the filter well enough. :)

Put the filter in the easiest place to replace it if you have to,once all the goodies are in place it might be a PITA to get at .

I was a bit concerned about the constant movement and vibration eventually cracking the copper pipe. I've turned up a couple of fittings and soldered the copper pipe into them. A slot in the fittings allows me to slide a small plate through to lock them in place.

Hi,
For obvious reasons, I would not be "cheap" when it comes to fuel conduction. Bare in mind the little cost of a couple of fittings is nothing compared to the cost of an entire car burning...
So, I would not connect the flexible hose directly on the copper pipe with a clamp, weather you solder an olive or shape a bead around, no. To me, the reasonable solution is the one shown by gaz05.

Use a proper fitting on the copper line, male or female, no importance

... and a push-fit fitting on the flexible hose, secured with a clamp. Make sure seats are compatible (if you bead a convex seat on the copper line, use a push-fit fitting with a concave seat and vice-versa).

When screwed together, it is safe and for sure leak-free.

Push-fit fittings come in any thread, male or female, convex or concave and any angle from 45° to 180°, so you can make a very neat connexion.

Regarding your filter, do you run an EFI? If you do, just a little tip (if you haven't thought about it yet): remember that the filter protects the engine, but it also has to protect the fuel pump, so it has to be mounted before the pump, and not (as we very often see when people come back with a damaged EFI pump), between the pump and the engine. Here is an extract of our catalogue (in French, sorry, but I think it is understandable) showing 2 typical EFI fuel line set-ups.

Hope that will help :)

Ahh great thanks for all the replies!

I did some testing today and the olives work very well. I have also made sure all the ends are clamped down within 1 inch of where the clips will be so will be very little movement.

I'm using a MX5 fuel sender that has a small filter attached to the pump further down the fuel line is the main filter.
