About once per tank of fuel i am having to remove and either flush or change my fuel filters due to the hijet stalling. When it does this it will crank, move 5 - 20 feet and stall again. Very aggravating! To give a little history... I added an electric fuel pump in line and bypassed the mechanical due to it not working and i didnt want to find a replacement at the time. I installed two inline filters, not counting the pre-filter on the electric pump. One is between the tank and pump and the other between pump and carb. I removed the fuel tank to inspect it and found a tremendous amount of rust and crud in it. I rodded what i could to break it loose and even put a few handfuls of gravel in the tank and shook it around pretty good. After all that i still couldnt get all the trash out. This is why the filters get plugged when the tank gets low. My next step is to remove the tank again and flush it with a water hose then let it dry. I have seen some of the tank liner epoxy but never tried it. Does anyone have any other suggestions, short of finding another cleaner tank? Thanks,
You've covered your bases pretty well. I have the same problem on an 84' model Honda three wheeler. Added filters, blasted it with gravel, etc. My best luck came from steaming it out with a diesel powered steamer. I turned it up to 300 degrees, steamed the heck out of it and then sealed it with one of those epoxy kits. This has worked great for years but I still kept my in-line filter and change it regularly. This is on a gravity fed fuel system. Luckily on your Hijet (worse case scenario), you won't have any problem locating a used tank here in the States. I can only speak for the Hijets, but it amazes me how little the little trucks have changed over the past 30 years or so. With that being said, the parts interchangeablity is amazing. Some of your parts dealers will offer that info up, some won't.
I had a similar problem on my 1977 Yamaha RD400. I looked at the epoxy kits but chickened out (or maybe I'm learning some things should be done by professionals) and had a local shop clean and line it for me. They also brazed up a few rust pinholes. Cost was reasonable and I don't have access to the equipment needed to do it right. Ralph in Winnipeg
