Sorry this is so long, but it is very important.
I thought I would post this since I am sure many have done what I did in regards to installing an aftermarket liftpump. I like many removed all factory fuel parts not needed ie feed line, lift pump and BRACKET, and fuel filter housing.
The bracket for the lift pump must be left on the engine as well as all 4 mounting bolts. You WILL leak oil and you possibly destroy your engine if you do not retain this. There is a gasket that sits behind this bracket that seals something that is used on a 12 valve engine. I thought it was just the block and just a mounting point for the pump, but it serves dual purposes.
I completed my Airdog install 1 week ago and have put over 100 miles on it with no sign of leakage or any trouble even though I did not have the bracket (just the gasket) which I thought was the block surface. I had put 2 bolts on to hold the wiring harness in place otherwise my gasket might have blown out completely.
I discovered this b/c I was installing a breather setup and had run an extension on the hose. While I was installing the tank, I tucked the hose up inside the bumper bracket and folded it in half to hold it out of the way while I was working (kinked restriction). My brother called and needed me to come over to his house on short notice, so I stopped my install and drove over there. I forgot that I had the hose kinked like that. This caused pressure to build up and it went out the easiest path (normally the dipstick) but in my case the gasket that happened to barely be sealing the hole where the lift pump bracket was.
When I got home, I noticed oil pouring from all under the truck. I look underneath and there was oil completely covering the whole underside of the truck. It looked like someone had poured oil out on everything - I mean it was everywhere. I still had plenty of oil in the engine, but after cleaning I discovered where it was coming from - where the lift pump was. Someone on CD mentioned there was a gasket there covering a hole that was not used on our trucks. I cleaned everything off with brake clean and installed the plate back on and put some silicone on the bolts and it was fixed. Added a little oil and cleaned up the under carriage.
This could have been a disaster had I driven further, not noticed the oil, etc. Especially if someone has a burned out oil pressure bulb or bad gauge.
So, please learn from this and check into it. It could save you a costly engine. Don't take a chance with the only reason we all own a Dodge - the Cummins engine.
