I have bought myself a Lada (don't laugh)  and have had some fuel related problems, i worked back to the tank as my pump and new filter had some curse word in them, so i took the sender out of the tank to find this.   now what you see is not rust but a kind of wax that has built up on the sender, i have found the same stuff in the new fuel pump filter, the fuel is a little stale i think, the car has been in a dry garage for the last 14 years and not turned a wheel, but the tank was almost full all that time, i know i need to drain the tank but think it best to clean it out also, i did think of putting a bag of marbles in the tank to help work the curse word of from the inside but wondered if there was anything else that could help? |

Nice Lada, not seen one that rust free for many years  I normally go with using some of the old fuel (strained if it's that bad) and a handful or two of clean penny washers and lot's of shaky shaky action. Drain, add a little fresh fuel and shake then repeat till the juice runs clear. Always on bikes mind but the rules are the same, had to use some red product once to seal a ropey Kawasaki tank but can't for the life of me remember what it was called. My dad had a light green estate same as yours he bought new on a E plate. Tree fell on it in that storm of 87, got repaired though and travelled many miles in it before he got a Sierra Laser Estate as a lease car with a new job. Wish we'd been able to stash the Riva in a garage somewhere for me to play with now. |

i did think that putting something else in to aggitate the wax stuff of from the inside would help, the bit that worries me is if there is anything in the tank that either the marbles or washers could become stuck in? the car is very clean with only some very small spots of rust the size of a pin head on the edges of some of the panels, i would think that when i give it a polish they will come off, i only have one other photo at hand right now of when i got it back when the weather was a bit better, there is one door trim missing on the left rear door but thats not a problem as i want to take the other bump strips off so she look's a little older   steam cleaning, marbles and the washers Mmmmm ? |

I had very similar looking deposits in the tank (and the rest of the fuel system) of my Triumph 2.5PI. That had also stood for approximately 15 years.
I used Swarfega Driveway degreaser (cheap from Toolstation), followed by pressure washer action on all the areas I could "see" through filler and sender holes. That allowed me to get about 75% shiny. Then made up a fairly strong solution of caustic soda (you can get the crystals from DIY shops for drain cleaning - read the instructions - it's nasty!) and soaked the remaining side for about 4 hours. Then shook vigorously, rinsed, shook, rinsed etc. It's pretty clean now!
Be aware that caustic is safe on iron and steel but will eat aluminium, braze, zinc plating, copper and brass so use it carefully....
I also considered buying 5L of gunwash (cellulose) and trying to dissolve it that way but didn't actually try it.
Good luck
Nick

I used this stuff for cleaning my petrol tank out. Tip it into the tank andshake the tank about leave for a couple of hours shake it again then tip it out and put the pressure wash in. Then leave tank to dry out. It is also great for cleaning rusty parts. www.maxwellsdiy.co.uk/product.aspx?id=48040 |

Be aware that caustic is safe on iron and steel but will eat aluminium I can vouch for that - I used caustic to dissolve a stuck aluminium seatpost out of a steel bike frame! It ate about half of the post before I managed to move it! Cheers Duncan |
