You responded with: > And that differs from what I said, in what respect? A minor point. It is the phrase: "...the engine will be under-fueled and will run a danger of damage due to running lean/hot." Diesel engines are _not_ in any danger from running lean. The only time it is _not_ lean is when it is creating maximum power - and when it is making maximum power it is also making maximum heat. Too much heat from too much power and important engine parts can melt. So the engine is in "danger" only when it is _not_ runing lean. Therefore, there is _no_ danger in using a stock pump. But it does seem rather silly to put a turbo on and not _use_ the extra air being pumped in.... Philip, nitpicking.
