You can have an air leak without a fuel leak, pressurize the fuel tank with less than 5psi of air, then go check for wet spots.

Thanks. Do you have a suggestion for a turbo to go with them? I was looking on eBay and I found some in my price range. I am sick of being in second gear climbing hills on the Interstate with my trailer, and if I have to replace the injectors I might as well go for broke and change the turbo also.

I'd go with a super hx40, or one of the smaller s300 variants that all the diesel performance shops sell. Or if you don't want to spend a bunch of money on a turbo, it seems people are doing well with the 3rd gen turbo the HE351.

Also personally I think i'd like to try some 6x12 or 6x14, but probably some 6x12 injectors. They should put out lots of fuel but still be small enough to burn clean while idling. My opinion, might be wrong though.

I just upgraded my non-I/C motor to a 54mm compressor and 3" crosspipe. It'll drop down below 300 in just a minute or two at idle. Before that, it would take about 3 minutes to drop to 350.

I suspect the I/C trucks don't do so well, since the restriction of the intercooler and you're not getting any cooling out of it when idling and sitting still.
