Installed fuel tank vent mod on '05 yesterday. Getting P0463 Code.

[thejeepdude]

Well, yesterday was the first nice sunny day that coincided with an empty tank, so I went for it. Removing the tank was easy, installing the kits was easy, but putting the tank back in was a little bit of a pain, although not that bad. Total time was probably 1. 5 hours, but that's because I was taking my time. For those of you worried about the fuel line and electrical connectors being a pain, don't worry about it. As long as you understand how they work ahead of time, it's pretty easy. The only hard part about mine was getting them reconnected with my arm around the tank while my body was wedged between the driveshaft and the bed of the truck. The other thing I noticed is that might be new to the '05 is that there is a metal ring with detents that hold the whole float/lift pump assebly in the tank, whereas the older models are threaded. Actually I think this is much easier and only took a few whacks with a screwdriver to get it open/closed whereas the old threaded collar design could be quite frustrating to get back on.



So anyway, I dropped the tank after driving about 25 miles past DTE (609. 3 miles on trip od), and flooring it at each stop to suck as much fuel as possible. When I finally got it open I noticed there had to be less than a gallon left! That was cutting it close. I thought this would be enough to get to the fuel station about 1 mile away. Well, it turns out it was enough to get to the station but it died right before getting to the pump! It took 4 guys to push the truck up to the pump. At least now I would know what 100% capacity is! She sucked down 37. 144 gallons to fill to the brim of the neck, and only required 2-3 top-off cycles to get it there instead of the 10-15 minutes of clicking it took before! I am very happy with this mod to say the least! The price and time required is far outweighed by the benefit. Thanks to spooled-up for putting the kit together so I didn't have to go searching for parts!



The only weird thing I've noticed is that I'm getting a P0463 (Fuel Level Sensor 1 High) code. Does "high" mean the fuel level is high, or the sensor voltage is too high, or?? It was probably there before the mod when I topped it off the hard way, and I'm guessing it will just stay that way anytime the fuel level is past what the float can read... no harm done I'm sure... or I hope at least! Anyone else who tops off to the neck get this code, whether you have done the mod or not?

It could be possible that running the truck out of fuel could have induced the code P0463... ..... I'm no expert by any means. Lots of guys have used Dave's kit... it is truely awesome. I've never personally experienced the code since installation of Dave's kit, nor have I read any posts from other members that have done so..... and that's quite a few. Best of luck getting it all lined out.

Well, that code doesn't throw any lights. I only noticed it because I was bored and decided to do the 3 times on/off thing. I'm wondering how many people do this without being prompted by a check engine light, and therefore would even know if the code did get set on their truck.

Mine has the same code, but I'm pretty sure my sender is trashed. At 1/4 tank the needle will drop to nothing and then come back, repetedly.



Where can I find out about this vent mod and will it go on a 98. 5? Sure woud be nice to top off easily, or at least use the commercial pumps at full throttle. 28 gallons in under a minuete? THAT'S a fill up!

 

[DGFoster]

I fill mine to the brim everytime,takes forever,but no codes on mine,where do you get this kit?I am tired of the 15 minutes it takes extra to get it full. .



thanks

Here's the thread that talks about it.

Amatuzio realized the need to begin with a synthetic basetock and build his ideal lubricant from the ground up. His search led him to Monsanto, Drew Chemical Corporation and Hatco. It was Drew Chemical Corporation in Boonton, New Jersey, where the first polyol esters had been developed and patented in conjunction with Mobil Chemical in 1958. Mobil Oil's Jet Engine Oil II was based on the fluids produced at Drew Chemical. The truth is, automobiles put even more stress on a lubricant than jet engines because air aspirated car engines must deal with dirt and the messy by-products of combustion. The problem was how to bring the expanded temperature range performance, wear protection and service life of a synthetic into an automotive setting. Amatuzio believed he had found a way. According to Jack Arotta, a Duluth Minnesota businessman today, "I was the first guy to put it (a specially formulated 100% synthetic motor oil) in a brand new car, a 1966 Ford Station Wagon. Al was my squadron commander up at the air base, so I always use the joke that since Al was my squadron commander, how could I not put it in when he told me to?"



Actually, for more than a year Jack had been putting a variety of Al's synthetic formulations in his previous cars, so he did not feel that he was putting his vehicle at serious risk. After several more years of fine tuning his formulation, AMZOIL (Amatuzio-oil) was created and became the first 100% synthetic diester based engine oil to pass the API sequence tests and receive API qualification in 1972.



The following year Mobil Oil began marketing the first PAO based engine oil overseas and in 1975 they began test marketing a synthetic PAO based synthetic in the U. S. called Mobil 1.

I do check for thrown codes on my truck quite often for the heck of it, never had one until here recently after having a couple TSB flash's done. Had a code show up about a week later that I noticed. Twice I heard a chime or ding tone reminding me there was a code thrown.

I traded my 98 12 valve for a 2003 2500 4 months ago and I am on the low end of the learning curve with it. What is the "3 times on /off" all about?

I *highly* recommend the vent kit.

Problem is with these truck is that to get them completely full of fuel you have to wait to let the fuel run down and get the air out of the tank,it has taken me up to 10 minutes extra standing there trying to get it full. .

 

[thejeepdude]

Well, just did my second fill since installing the vent mod. All I can say is, WOOHOO!

Your talking about getting codes? This is an old chrysler trick, but it went away on our trucks for a while in the late 90's.

Tur the key ON (no start), then off, on, off, on. Cycle about 1/2 sec. but not more than one sec. and the P-code should appear in the odometer screen. Older stuff would use the check engine light to sequence flash the number. (5flashes, pause, 2 flashes would indicate code "52")



There used to be a code that ment "no codes". ??? the '03 might display "none" ???
