Looks like I’ll be treating the tank to this process in the next few days. But before I do I had a look into the tank through the sender hole and noted a swirl pot in there underneath the pick up pipe. There are two curved pipes feeding in from either side. I’ve tried feeding a wire through them but not sure I can get it through the ends into the main tank. Has anyone ever opened up a tank able to tell me how long these tubes are? Obviously a little concerned that tank sealer might block these pipes rendering the last couple of gallons unusable!

Guy,
The later tanks, coupled with the later fuel pickups (together with
the fuel level sender without pipe) had a mesh filter which you can't see
from above. This mesh is quite fine, and would probably be blocked with POR15.

I think yours will be the earlier version, with the fuel delivery from
the sender unit. If that's your type, I don't think it will be an issue.

I suggest using an old speedo cable inner/s to keep the pipes open, turning and moving
during the curing time.

Best wishes,
Nigel

Cheers Nigel, I've got a NOS fuel sender that's identical to the one I just destroyed today, it wasn't giving a reading on a gauge and was gummed up, the filter was in the bottom of the tank too but easily retrieved. I'd tried a bike handbrake cable through the various pipes on the tank but struggled to get it through these 2 pipes inside the tank - until I found a piece of copper brake pipe I could pass it through and then bend to get at the ends of the pipes through the sender hole. I suspect they're just full of crud at the moment and that the tank cleaner will dissolve all that.

The idea of an old speedo cable is an excellent one - I was thinking of using a dremel cable, it's the same thing but an old speedo cable is a much better idea plus it's disposable! I think I might even have a bit of old fire extinguisher pipe to use as a guide for it. I feel a plan coming together!

I was struggling with getting a bung to seal the filler pipe too, I thought about a cork from a home-brew place or a rubber one but couldn't find one nearby. Then I realised I had a spare filler neck with the rubber connector pipe still attached. And a top from an old caustic soda bottle was a great fit, especially when clamped on. I just need one short length of rubber pipe to seal a pipe and the work can start!
