landcruiser fuel hammer

Sorry mate, When i'm just taking off or when slowing down under revs, sounds like flicking a ruler on the edge of the desk.
Toyota said its a common problem on some ealier models, and they changed it on the later models, they said they fix it with a fuel dampner???
Do you know of this type of problem??

I had it in my 79 series, toyota put a dampner in the fuel line, have not had it since, that was 4 yrs ago.

I driven a number of crusiers from 47's to 79's (plus a 60 and a 80), I have not heard of that one before and I have driven some station toyota's too. If that is the case, it should only be loose/missing bolts or rubber somewhere along the fuel lines. Check it anyway as it shouldn't happen.

Only happens to the 1HD-FTE motors in the 2001-2002 78/79series. For whatever reason, Toyota skimped on the dampeners that they put just upstream of the injector pump on other models.

So, you're talking about the injector lines themselves? Between injector pump and the injectors.

"you're talking about the injector lines themselves?"

No. Sorry, I may have been confusing with the term "upstream" which I meant to mean back towards the fuel tank.

The steel fuel pipe that runs along the firewall between the fuel filters and the injector pump is the source of the noise. The vibration is transmitted back from the injector pump. The factory fitted dampener is located on the inlet manifold on the inlet fuel hose.

The noise is most pronounced when you're off throttle and at low speed - get it constantly when 4wding in low range. Sounds a bit like an exhaust brake.

Cheers
