We did it with a set of a sunbeam alpine (no baffles) tanks and we could really see the flakes coming out when we emptied it... we did use little stones...
We also partially did my tank while we were at it and although the baffles might be in the way it works, you might have to hold it in a certain position to get the stones past the next baffle but it will work.
Afterwords we got an epoxy sealer that was specially made for these applicatons and coated the inside of the tanks car still drives great without any problem!
Hope you get it fixed David!
Good luck, Thomas

I like a car that looks normal but really knocks your socks off!!
Yes, I was sceptical, but hearing from someone else that it works; well, I'll go for that. Might be something I need to do on the kack-hander, but I hope not. Running OK at the mo. except for too rich due to seals in carbs that need to be replaced. Will update on that thread in due course. Cheers. G. |

| Might be worth it to make sure the mechanical fuel system is ok by borrowing an electric fuel pump and installing it temporally and feeding it with a 2 litre bottle or similar - see how it runs ? |

Good point Janmarine3,and I think i've got an old Facet somewhere. But if it is tank partial vacuum causing the problem, it may take a while to build up some suction...! Anyway, I'll get the tasnk out and the fuel line off for a good inspection on general principles. After all, everything is 40+ years old, si I wouldn't be surprised at some deterioration in the tank lining/fuel pipe...

Hi Guys,
Took Phoebe to a Rolling Road near me (Launceston) and got very interesting results. Mark told me that in spite of the carbs being absolutely to spec and fully cleaned etc, she was running very lean. He changed main jets, pump jets and tweaked the air correctors- result - she now runs very nicely indeed. He also said that from work he has done on other H120s, he feels the original air filter set-up is very restrictive- and draws hot air from near the manifold. Now getting 80-90bhp at the wheels which I guess is about 110 at the flywheel. Sounds about right, and certainly feels good on the road!

I know its an old thread but I had the same problem with my Rapier over 20 years ago. The problem is if the tank has been left empty or with very little fuel in. The coating on the inside of the tank 'drys out' when fuel is reintroduced the dry coating takes in the solvents in the fuel and starts to lift. It tried everything at the time (I remember an AA patrolman telling me this info and saying it was a big problem with hillman hunters and avengers) I tried constantly flushing the tank with fuel agitated with nuts and bolts (as mentioned). Once left a few weeks the problem returned as more paint flaked off.
Now, here's how to kind of fix the problem. the fuel line exits from the bottom of the tank via a coupling located in a threaded low point or sump. this, by nature, collects all the flaked paint and does a good job of gathering all the particles in the tank ready for there route to the fuel pump. some flakes can be that big they will actually block the pipe at the tank end. This can be temporarily fixed by un-attaching the fuel line at the pump and blowing back down it. For a more permanent fix, get a small length of tube and insert it into the metal tank union, so the tube sticks up about 10mm into the tank. drill a few small holes in it and make sure the tube is a tight fit in the union. Next fit an in-line fuel filter (a largish one). After doing this I never had the problem again. Just worth giving your tank a flush ever 12 months and changing the filter. Sure, the tank still flakes but now it stays away from your pump and carbs. |
