Thread: TD5 fueling problem question

to test for injector seal blow past simply fill the tank to absolutely brimming full and start it up. if it bubbles for more than a few seconds to a minute and the level doesnt drop down by about the amount of the bubbling you have injector compression seal or nozzle blow past possible a venturi leak on the return line from the filter to the tank.

to test the latter, just take the line off the tank end and put it into a very large bowl, run the prime sequence and watch for bubbles.

Thank you! the excess fuel is diverted to the return line by the FPR! of course.

An update on the td5. I replaced the injector washers and o-rings today to good effect.

Next step is to get it into the shed and give it a good service and have a look for what else needs fixing on it.

No doubt there will be more questions down the track.

Good drills,

I know a guy, good mechanic on the td5's. It wouldn't take much of an arm bend to get him to drag his other half out out your way for a weekend to give you a hand and have an explore around the area.

drop me a PM if you'd like I'll give you his number
