corona fuel lines into ra40 celica

[barned01]

well after a monumentally generous donation by the chuckster, i have now embarked on replacing the fuel tank in the ra 40 with an in tank fuel pump variety.
The fuel tank is from a rt142 corona (i think....i picked it up 5 years ago).
at that time i also grabbed the 3 fuel lines from the corona.
Now there are threads on here that say this should all fit with minimal effort and this does look to be the case BUT the damn fuel lines look like it could be a significant effort.
it looks like the return line and the line to the charcoal cannister look like they are the same size so i assume the only one that really needs replacing is the main supply line.
So Assuming I replace this one line, how much has to be removed to get the old bugger out and the replacement back in?
So Far, the car is jacked up on the rear axles with the front wheels still on the ground (so minimum clearance between axle and underpan and all the weight on the front wheels) . The main hurdle looks to be the steering box. I assume i need to remove it or at least loosen it substantially to get the old fuel line out. Will everything all go pear shape if i start to loosen it considering all the weight at the front end is still on the tyres?Is there another way to get the old line out and the replacement one in? do i need to somehow lift the front of the car up as well? do i need to have the engine removed so the gearbox isn't in the way? etc.
For those that have done this, what did you have removed/ jacked up in order to get enough clearance to get the replacement line in?

cheers

I tried to do this and then gave up. factory hard lines supplied enough fuel &
pressure for the turbo motor. i just replaced any hoses post-pump with efi-rated stuff and used decent clamps where used.

Hi I have done this on 2 ra40's but they were converted to rack and pinion for 3sg engines and the engine and gearbox was out of the car at the time, you are correct in only replacing the fuel line which is larger for the fuel injection motors
You will be ok to loosen the steering box but you may need to separate the linkage as well, (lot of pain)
also you need to protect the line where it runs under the foot well

I should point out that unlike Graham ^^ I tried to do it with everything in place and the car on short jack stands.

so like chuck ^^ doing it (the fuel line that is) with all parts in situ, makes the job super tricky...
i can roughly get it in place, i will assume i can take off the gearbox xmember to get the line up and under that, but when it gets to the engine bay, it's a bit blargh.
i will see how i go with the steering box tomorrow. Although I wonder if just getting some new line and forming it in place might be easier, is new stuff easy to bend by hand or will it still be a pain unless all the crap is removed first?

I had already swapped over the tank and had other issues to worry about - so I was probably short of enthusiasm. I also had no pipe bender so was resorting to trying to re-bend the line around random workshop objects - which combined with the lack of enthusiasm doomed the whole process
