The swirl pot is attached by 4x rivnut & bolts to be removable, it looks skewed compared to the chassis tube, its square with the panel though, the tube runs at an angle.
(Still not completely happy with that brake line... it might move before it gets fixed)
Trial and error with the fuel pump ties - one needed to be above the lip on the pump can so it cannot move up or down, I only worked this out after fitting it along with its main inlet hose - the hose was trying to push the pump upwards & would have easily pushed it right out with the vibration of running.
Note - hindsight - the pump needs to be fixed with metal clips or fuel proof ties - normal cable ties are not good enough.
I needed to get this bracket on before the side panels to get to the rivets:
Not a great example of drilling here - opposite chassis member combined with bad technique let the drill wander.
Rivnuts holding the fuel pump; the middle one plugged with bond and unused once I realised one attachment needed to be above the fuel pump lip:
All ready now to connect the fuel lines from the LP pump at the back to the swirl pot.
