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 picture with too much shocking condition). Now I understood why the fuel couldn’t come.

As the tentative solution I removed the rust from the unit and put the net at the inlet of the pipe not to come the rust in the fuel pipe, and reinstalled the unit in the tank. I have to remove the rust of the tank and replace the fuel sender unit with new one. It’s my future task with high priority.

When the fuel pump started, finally the fuel came to the engine room! A little progress!!!

But soon I found new problems of course …

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....

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 t...

Brake master cylinder overhaul #4

I disassembled the brake master cylinder again I repaired on the other day because the behavior of the piston seemed to be not smooth enough. When I removed the piston at the last time , I checked the condition of the rubber and it looked good. Therefore , I reassembled it without replacing the rubber. However , again I disassembled the brake master cylinder ’ s piston and checked its condition carefully in order to reassure myself. I disassembled and cleaned the piston and the spring. The condition of the original rubber was not bad , but I replaced it once with the rubber part of the repair kit. Again , however , I felt that the quality of the rubber parts of the repair kit ( left one ) seemed to be poor…. I also assembled the piston into the cylinder as a trial , however , the tight contacting feeling was not enough. As my conclusion , I judged the condition of the original rubber parts were good enough and decided ...
