We have a 2001 Itasca Suncruiser with Ford F53 V10 gas engine.There was a technical service bulletin for water injestation into the air intake. At times, during heavy rains while driving, the air intake would suck in water, drowning the air filter and causing the engine to stall or lose power. The fix for this from Ford (since parts are no longer available for the fix) was to use a dryer vent hose and reroute the air intake higher up inside the hood. I did this, but the problem continued. So, I brought it to the Ford F53 service center and they suggested that I raise the dryer vent hose even higher inside the hood, so we did that (raised to the maximum amount pointed the open end toward the rear). But still the problem continues. Water gets sucked in while driving. I am using the flexible aluminum dryer hose. Has anyone had this problem and what is the REAL fix for it (other than not driving during rain of course). ???Does the Banks Cold Air Intake fix solve this problem??

Banks intake will solve the problem. Plus, combine it with a free flowing muffler (which you're probably due for if you still have the original) and you'll gain a little more power too. Note: there's plenty off muffler options besides banks which work as well. I went with magnaflow last time around.

Where is the dryer vent hose pointing to or at? Have you tried pointing it back towards the fire wall behind the engine?Bill

We even have the dryer lid on the hose (with the flapper removed). This is pointing to the fire wall, not open toward the hood.

Did you make a big p trap at the bottom before bring it to the top. And the Ford models had a type of duck bill sober drain at the bottom so water in the p trap drained out.

It would appear that there are 2 factory holes (about the size of a nickle) in the air filter canister assembly (usually hidden by the rubber strap) that are able to suck in water. Surely these should be covered?

The holes are inspection holes. I used some plastic plugs to take care of that issue

thank you! YES. I just covered these two holes with some foil tape. If it was possible for the outside of the canister to get wet, it was also possible for water to enter via these 2 large round holes!
I will likely install the Banks cold air intake that is supposed to take care of this water injestation problem, but for now it is ducttape and foil tape to the rescue.

I have done the dryer vent hose on my 2002 and have had no problems since. I did leave the shield on at the bottom of the intake and just cut enough away for the vent hose to come out. The open end of the vent hose is just about even with the top of the filter housing.

The drain tube is flat at the bottom end similar to this:

The weight of the water in the tube will cause it to open. When the water is evacuated the end closes so no air or moisture can be ingested

Post #12 shows the Ford version. Note the flat rubber drain at the bottom of the tube about 6" to8" before the filter

Thank you, yes I see the post#12 picture, but I don't see the rubber drain at the bottom that you are referring to. Wouldn't the rubber hose 'suck' air also and pull water into the system also?

I used a flexible plastic rain spout extension to form the snorkel for my F53. At the bottom, I drilled a couple of small holes and covered them with a one-way flap made with folded vinyl tape.

It made the SERVICE ENGINE LIGHT come on. Scangauge returned a code P0103 which refers to the air flow sensor detected a problem. It was very wet inside the area where the airfilter is located. Very frustrating since I have performed the modification that Ford says to do. The air intake is somehow able to suck in water even with the modification. I am afraid of drilling a drain hole as suggested because I am concerned it will suck in water thru the drain hole instead.

Have only had that issue a couple times, usually when it is raining so hard I am looking for a safe place to pull over. I carry a spare air filter so I can swap the dry one in if the air filter gets saturated. Try to keep your intake away from the wheel well and protected from road spray as much as possible. Provide a small hole (1/4") in the lowest point in the "J" so that water can drain out.
