Can anyone give me some details of the position and securing of the hard plastic pressure and return pipes for the injection fuel supply.

I have only the pipes with the foam protection and don't know how they are secured. I'm trying to keep it factory spec.

Mainly I'm not sure about how they are secured comming into the gearbox area from the chassis box section. My car was stripped of all fixings and was a carb model anyway.

Generally they come onto the exhaust shield with the injection pump mount with the pressure feed hooking into the pump and return longer and looping around to the tank. This all fits under the gearbox with the tank lobe joiner pipe, I think this was secured with a plastic hoop that locks into the shield.

What does the main filter bracket in the Engine bay bolt onto, is this the same bracket the renix sits on? Unfortunately I removed mine thinking it would not be needed.

Not sure about the fuel line securing as mine was carbed as well. Mine just come out of the chassis box and go directly to the fuel pump, ive not secured them, just ran them on top of the metal plate.

The fuel filter does bolt to the same bracket as the renix bolts to. It only uses one hole on the side. Can't be to hard to find another spot or fabricate a new bracket to mount the filter to.
