Thank you. I know where my low air light is. I don't have an alarm and thought I should have from the factory.

I am looking to find where my low air alarm location is. I have never heard my alarm in 8 years of owning my coach. If someone with my coach can send me a picture of this part or information so I can find one, I will buy lunch and beers. With all due respect, please do not reply if you do not own my vintage of Monaco Knight. Thank you in advance.

I installed an AirDog only pump and retained my 2 fuel filters. I added a Goldenrod filter before the pump. Here is my install at post #116 here: https://www.irv2.com/forums/f123/caps-fass-and-airdog-518703-9.html. There are lots of ways to skin a cat.

Interesting. You are the first poster that has said this.

I think my coach is your coach.

Better off to check your wiring as this is the major problem with coaches. There is tons of information on a mod that uses Bosch relays. I did this mod on my coach and the difference is night and day. A good read for those not sure of what I am talking about is this from Daniel Stern. Anyone good with a 12 volt test light can do this upgrade.

A guy on another forum put that performance module on his rig and swears it did wonders. Anyone with a rear radiator set up looking for more horsepower should look up Source Engineering and the fans they sell. I put one on my coach 4-5 years ago and I could tell a difference right away. Cummins cannot turn up (or won't turn up) an ISC motor. Here is a link to the fans. The fan doesn't give you extra horsepower, it give you back horsepower that the OEM fan stole.

Hey for what its worth, mine had a smell like diesel, an after my bypassing the lift pump and capping off both the inlet an output i too had a small seep, causing concern. I washed the out side with parts wash liberaly, let it dry an then drove it several miles, then rechecked it and it was dry. My pump issue was not a leaking gasket as much as mine had been leaking out from the connection where it plugged in at, i suspected the motor cavity had actually been filled with enough diesel fuel that it took it a while to M/T out, i have just compleated a 2300 mile trip an its drier than a popcorn fart. From what i understand the return line fuel does not have any “pump” cavitys, instead it supposed to be just apassage  way thats channeled thru the assembly. To be fair i have never held a lift pump in my hand so that part is just hearsay. Perhaps someone out there who has actually looked at the passegways of the liftpump can comment on that.

Thank you, this is what I am hoping it to be. Someone on another forum posted this and I will check in with him. See post 144: https://www.irv2.com/forums/f123/repeating-caps-failures-need-help-289659-11.html

Hello All, I have recently completed an AirDog only pump installation and I have about 45 highway miles of an uneventful test drive under my belt. Everything seemed perfectly fine and I didn't notice any leaks when I got home. On my installation, I capped off the fuel inlet and outlet of the lift pump with 10 AN caps. I left the return lines as is. I mounted my AirDog pump in the bay where my fuel tank is and I am pushing fuel to my factory 2 filter set up. Pretty straightforward. The AirDog pump was preset at 15 psi and that is what the running pressure actually is as I installed a gauge. Today, I started the engine to reach full air pressure as I wanted to chase an air leak. Once it reached full air, I turned off the engine and got underneath with a bottle of soapy water. While under the engine area with a flashlight, I noticed fuel leaking ever so slightly out of the bottom of the lift pump. What? How could that be when I have it capped off? No banjo lines are leaking on the lift pump and neither is the return line from lift pump to tank. Is it possible the manifold is bad and leaking into the diaphragm area of the lift pump? Or, is it just fuel left over in the lift pump possibly leaking out. I am now trying to understand if there is a way to bypass the complete lift pump manifold with the 2 banjo hoses mounted to it? FYI, I only did this mod as preventive maintenance, not because I had a leak or running issues. Any help would be greatly appreciated. Thanks in advance.
