Fuel tank repair: Day 1 --- new mission started!  

I’ve started the new mission that the repair of rust fuel tank.

The replacement of the rear bearing at the rear axle was still on the way, however, during summer holiday I could secure a longer time, and the hot climate would be good for the chemical reaction of the rust remover and drying the inside of the tank.  Therefore, I wanted to repair the fuel tank in summer holiday.

The target of the 1st day was to remove the fuel tank from a car and to put the cleaner “MARINE CLEAN” into the tank.

At first, as a preparation for the tank removal, I removed the equipment in the trunk room, such as the electric fuel pump, battery, which may interfere with the work.


Next I removed the fuel sending unit and extracted the gasoline inside the tank with hand pump.  Considerable amount of rusty objects came out together with the gasoline.



After extracting the gasoline I started to remove the fuel tank.
Firstly I removed the screws at the flange of the tank.  Some screws were covered by the sealer and not able to be loosened by a screwdriver.  I used a vice pliers to turn them.

Even removing all screws, the tank was still sticking on the trunk floor panel by sealer.  So, I pushed up the tank using a floor jack.  Then, the tank was separated from the floor.


While doing this, I was worried that a tank would be punched at the bottom by pushing the tank with a jack, but it was okay.

After this, I tried to remove the tank from the trunk room and it took more than half an hour.
At the beginning I tried to take out from the top.  I did lots of trials changing the angle, however, I couldn’t.  Then, I thought that the tank could be dropped down.  I did several trials overturning the tank, and succeeded in dropping the tank down on the ground.  It was a very acrobatic movement, like a Rubik Cube!!!


Finally, I put the MARINE CLEAN into the removed tank.  They say MARINE CLEAN can remove the sludge and gum in a tank.  In order to cover the tank, I cut the pipe of the old fuel sending unit and crushed it.  (It was useless because it did not work properly due to rust.)


I put the 1 liter of MARINE CLEAN and 1 liter of boiled water in the tank, and had to leave it more than 24 hours.  They said that the hotter condition   I heard that a hotter condition would give better results, so I would leave the tank under the scorching sun tomorrow.


I had a lot of sweat through today’s work in very hot climate and reduced my weight more than 1 kg. ☺︎

So far, the work has been doing well as planned.  It was very unusual.
I had a good feeling this time♪♪♪

Tip to repair rubber parts

I disassembled the rear axle before.  There had been no progress on it because I started the repair of the fuel tank during my summer holiday. While painting the fuel tank , I repaired the torn rubber boot of the parking brake wire. I guessed it didn ’ t cost high because it was small rubber part.  But I wanted to try the repair method I read on the magazine article before. This was the condition before the repair.  The rubber was torn apart and separated almost. I used this self-adhesive type butyl tape.  I pasted lots of small pieces of the butyl tape on the back side of the rubber boot.  As time goes by , these tapes would melt and stick together.  After this I applied plenty of adhesive “ Super X Black ” on the rubber boot.  On the magazine of MOTO MAINTENANCE , I read the article that the motorcycle seat was repaired with this method.  So , I wanted to try it. After drying 1 day , it became like this....

Brake master cylinder overhaul #1

I started the overhaul of the brake master cylinder after the clutch slave cylinder. This day ’ s work was removal and disassembly of the brake master cylinder. My “ onboro ALFA ” is early type ( Mk. I ) 1750GTV RHD.  The brake master cylinder is made by BONARDI and it is installed on the frame under the floor together with the clutch master cylinder ( this is made by BENDITALIA ) . Regarding the removal , there was a little try and error. ( 1 ) Remove the pipes Then , I tried to separate the linkage rod connecting to the brake pedal.  However , the fixing nut was so hard that I changed the process. ( 2 ) Remove the bolts fixing the brake master cylinder on the frame. ( These bolts were also fixing the clutch master cylinder penetrating the frame. ) ( 3 ) & ( 4 ) Separate the linkage rod from the brake pedal , and remove the brake master cylinder together with the linkage rod. ( The linkage rod and the pedal were fixed by a split pin. ) ...

Fuel pump (The original blog was written on 15th Aug. 2007)

Although the gas was refilled , the gas didn ’ t come to the carburetors.  The electric fuel pump was working , but it still did blank beating.  I replaced the pump soon after I bought this car…but it was about 20 years ago!  So , I decided to replace the electric fuel pump to new one , and to change the location of the pump from the engine room to the trunk room ( because for the electric fuel pump to push the fuel is better than to pull the fuel ) . I bought the Mitsuba electric fuel pump , fuel hoses and a fuel filter by auction and installed them in the trunk room.   ( The wiring is tentative.  But I am ashamed because the trunk room is so dirty… ) However , even the new fuel pump was working well , the fuel didn ’ t come.  I guessed that the inlet of the fuel sender unit in the tank was sticking.  I remove the unit from the tank and found the rusty unit and its inlet was perfectly blocked by the rust ( I forgot to take the pictu...
