Gauge installing
 

I just orders the glow shift gauges. Fuel pressure, Exhaust temp, and boost pressure. I was wondering besides the electrical part, how to install these to the engine? What peices such as bushing ect.. will i need? and how and where?

boost pressur hooks into the intake manafuld. there is a 1/8" NPT plug in were it goes it is located between the pump and head on the side of the intake. your boost line goes there. pyro- you have to drill and tap your exhaust manafuld were the 6 ports meet. dont go directly in the center there is a rib ther ofset it toward rear or front. unhook the turbo so the shavings dont make there way into the turbo. as for fuel pressure is it electrical or mechanical. mechanical(great) electrical(send it back)

this is just my opinion but i would put the in the elbow right after the turbo. Cummins designed a small raised spot with a small dimble in the middle of it. that is where cummins designed it to go. It took me about 25mins to pull the elbow and down pipe out drill it tap it and reinstall it. I was told by the truck shop foreman at my work to put your EGT after the turbo and one of the Engineers on the 5.9 told me that also he is also the one who told me about the dimple

only reason to put it behind is so if it breaks off after time is so it dont eat your exhaust wheel. i have never seen anyone do it post turbo around here, plus you will fry your tubo before you know how hot you really got. i could care less what behind the turbo is that aint important its what is in front of the turbo that counts

Not to say your wrong or anything just do not understand why cummins would cast a spot in the elbow and recommend it there:humm:

we moved my buddys probe from pre to post and it did not make much difference just barely enough to see on the gauge

I have heard that you can put the pyro in the manifold without removing the turbo. :humm: With the engine running and some grease on the drill bit slowly drill between #3 & #4 exhaust out at the flange where the turbo mounts.
I read about but have not tried it. ( Mine is post turbo )
If you go post turbo you will need to add about 250-300 degrees to the reading.:humm:

if they cast a specific spot why didnt they just put one in? all our dump trucks, Cats, cummins all are preturbo, cummins northwest inc and western states caterpiller told me that was the dumbest idea for putting it post turbo because your not getting an acurat reading for crutial parts, it safer to be accurate on a $1000 like mine or a set of twins lot of money to be throwing away for 6" of variance

yes it does make a differnence weather it be post or pre, you can do it by drilling slowly with oil but i didnt want to take a change. we dont remove the turbos at all we separate them from the manafold and put a rag in there, drill it, tap it then start it up to catch all the debrise

Mine is preturbo and its staying that way. Its too risky to guess at what the exahust temp is.

:humm:

Isspro gauges have both pre or post turbo gauges.

I'm going to wait and put mine pre-turbo when I get a new pulse manifold & turbos. As of now I run my defuel on 950 degrees to be safe.
