01.5 Intake horn-grid heater gasket

[BigUgly]

Oops!

I was helping a buddy of mine install gauges on his 01. 5 auto. He wanted to install the boost fitting on the intake horn, not in the Cummins Port. Now, I have removed the intake horn at the grid heaters on my 2000 at least 3 times, and I've been able to reuse that durable metal gasket. Well, we went to remove the horn to drill into the back, and made a discovery. The gasket on his truck was paper! One of those un-reusable paper gaskets . "Oops!"

Fortunatly, we were doing this at a local Marine engine shop owned by my buddy's friend. Did you know that the gasket on the Cummins Intake horn is nearly identical to the gasket on the exhaust horn of a Mercury Outboard? I didn't! Fortunatly, it worked. However, anyone that wants to remove the intake horn or a 2001. 5 might want to think about getting a gasket ahead of time.

Now, I wonder where I can get a 'Mercury Powered" plate for my friend's Dodge .

Yea, My truck was "down" for 2 days waiting on a new gasket. Now I know why others said the gasket would not need replaced.

You can drill the intake without removing the intake , remove the clamp on hose pull hose down cover with plastic or other cover move out way stuff lint free rag or plastic bags ect up in horn past place to drill ,drill and shavings fall out , whipe and replace hose and clamp when finished with drill tap and fitting . I put my fitting on top where horn starts to flatten out from the round about six in from the hose up stream. Saves time and is easy no brainer. Hope this helps and saves down time .

Excellent Ron... that is one of the ways Robert Patton instructed on the Geno's Garage gauge installation instructions.



However, there is an even better way...



Piers designed, fabricates and sells a trick boost fitting that replaces one of the intake manifold base bolts (one of the ones not used to hold down the intake manifold runner). Just remove the OE intake manifold bolt, screw in the trick boost fitting, torque to spec. and your boost gauge can then be connected to the exposed end (this fitting is hollow... the intake manifold threads into the head are not blind, thus allowing access to manifold pressure). All this for approximately $15.



Awesome fitting Piers!

Heck, there is even a better way. There is a plug in the rear of the 24 valves at least. Just forward of the MAP sensor. It takes a couple of brass adapters to get the size down to the right size. No drilling! However, my friend wanted to drill and place the sensor on the rear of the horn to give him more slack with the boost tube, and we didn't have a 90 degree drill. It all turned out okay, however, I have been corrected... . It was off of a Mercrusier 4 cylinder Sterndrive.
