5.0GN tow

Very nice job, new frame looks very well done. That factory frame was a disaster of a design. Your new frame is a beast, you wont break that one.

Makes me glad my "camper" is a actually a horse trailer built on a stock trailer chassis. Its only 32 ft long, with an empty weight of 4550 and GVWR of 16900. Not quite as luxurious as a true RV, but very very sturdy.

I was going to get it finished up and wieghed today but apparently the F1 50 decided it wants U joints.

The best laid plans, so they say.

I got the garage all cleaned up last night so I can get the truck in.
But I still need to do a couple things to the camper so I can move it out from in front of the garage soon as I walked outside we had a downpour. Very gloomy nasty day I suppose that means Hillary Clinton is going to win Lol. Guess I'll work on put my bead locks together for the rzr. Really thinking about trading F150 in on a f250 got a couple things going on with it broken header bolt on the driver side and has now burnt up the catalytic converter that I just put on there in February and the heater core is leaking.

Not sure if you caught it the first time but never just change a cat convertor. Cat generally do not fail on their own, they are a symptom of another problem upstream.

The most common cause is a rich exhaust (some kind of flooding happening) which causes the inside of the cat to begin to melt. You need to figure out what is causing the rich condition upstream to stop losing cats.

Yeah I know the first time it was a fuel pump issue . I had to travel for work to Dallas Texas that's when the exhaust started leaking nobody down there wouldn't touch the manifold for under $2000 so I drove it home that's what melted the cat .

A leaking manifold will not cause a cat to melt down. If anything you might run into a lean condition, which should not damage the cat.

This also holds true for a fuel pump issue. The only possibility there would be a lean condition if the pump was not supplying enough fuel. Again a lean condition will not damage the cat.

You need to look for something causing a rich condition, that is your culprit. A misfire, even one small enough not to produce a code, can cause this. You need a specified number of misses during a specified duration of time to cause a code. Only a scan tool that will display live data will catch that.

Fuel pump did cause the issue low pressure was slowly filling the exhaust and cylinders with fuel. After a lot of cranking it would start and smell like straight fuel coming out of the exhaust. Manifold is letting air in to the exhaust pipe fooling the o2 sensor in to thinking it is lean so it adds more fuel that is not being fully burnt. I have had it on a live data scanner to confirm this.

I would actually like to see that. There is no way air is working its way into a leaking exhaust manifold with the amount of pressure inside.

You have huge amounts of pressure inside that manifold when the engine is running, much higher than the outside ambient air. There is no way to cause a draw or vacuum into the manifold with higher pressure inside than out.

What you are stating happened is not possible.

This would also explain why you have melted down another cat, you thought you solved the problem but did not.

As for the first part, a fuel pump with low pressure will not cause excess fuel to get into anywhere, it would cause a lean condition.

You may have in fact had a bad fuel pump, but that was not what was causing your rich condition on start up.

Again, making these incorrect assumptions is why you have lost the cat again.

I know it is hard to tell here but I am trying to help you out and anyone else that reads this thread in the future.

It is 100% why the first cat failed with out a drought. I did the live data on it.wich only showed inconsistent fuel pressure. I would go to start it and it would crank and crank and eventually start. It would start because lack of fuel pressure and it would slowly build up in the cylinder until it fired. Once it did the exhaust would smoke for quit awhile. The new leak I did not run live data on This is a leak at idle and low rpm but at full throttle it becomes a vacum. I am told I am not going to Argue with you over it. That is not what this thread is about.
