I just welded up the broken tab on the bracket when I had a problem with my 91. Didn't even have to drop the pipe.
Can't see why the replacement with the rubber hose won't work. Should be the easiest/cheapest solution as long as you can clamp the hose off well enough and secure underneath. Go for it.

Rubber hose on there has an OD of 30.5mm so I'm picking that the pipe is 25mm, so the tube is 25mm ID. Clips need to cover the 30mm hose.
A good quality heater hose by the likes of Gates or Goodyear will most likley outlast the car if carefully routed.

Re: Heater pipes
We have 3 SW20's, The first SW has had the pipes replaced with rubber heater hose which as far as I can see negates the problem occuring again.
The second SW has had the heater pipes replaced with new ones. Rangiora Toyota helped out there particularly with the price of the pipes. When I purchased them the cost price from Toyota was $1200 for one and $700 for the other. Because I was a member of the MR2 club I got both pipes for around $500.
The third SW has had the problem recently occur and I was thinking because the pipe is copper of getting the pipe brazed. The fracture of the pipe is in the same old place, on the last join where the heater pipe has the tab coming off to bolt to the car.
Basically its up to you, and how much money you have got

Re: Heater pipes
That was a wee while ago. I think you can still get one pipe through Toyota but they are still very expensive. I will just be doing the cut and apply rubber hose technique when I pull the fuel tank.
I was going to try and find a crox tool to flare the ends properly but it sounds like people don't even bother doing that and it works fine.

Re: Heater pipes
Just so you know the heater pipes don't need to be removed when dropping tank. By disconnecting from brackets they can be pushed out of the way....I will just be doing the cut and apply rubber hose technique when I pull the fuel tank.

Re: Heater pipes
All good, I will be chucking a walbro in when I can be bothered so just made sense to do it at the same time.

Re: Heater pipes
I put a Walbro in as well. Wrapped it with some rubber to isolate & sound proof so noise didn't come into cab. Can still be a little 'whinny' when tank is under 1/8 full tho.
Note that the pump is smaller than OEM but pumps a higher flow & pressure. It won't be a direct fit into the bracket so be prepared to slightly modify a few things (cabling, isolator, outlet hose, etc).

Re: Heater pipes
That's awesome, thank you. I got it from prime driven with a fitment kit so hopefully has everything. I also ordered a new oem fuel hanger from Toyota so I can sort it out before even dropping the tank. What sort of rubber did you use? I guess they call them whinebro for a reason.

Re: Heater pipes
Even with the kit it takes a little work to install in bracket. Not a big deal especially if you are using spare part.
On the wrap around dampener I used some 5mm insertion rubber I had at work. To be sure fuel didn’t degrade it let sit in a test tray of it overnight. Walbro sell a foam sock to do same.
