Without having something to check pressure, I'd say it's probably just old lines. If I was you I''d tow the trailer around town close to home and have a spare on hand. Could just have been time to replace em. Usually when one of anything that has a mate goes, the other is close behind.

I agree. Now that you have them both replaced, you are probably fine to tow again. I tow an 11,500 lb toy hauler, and it is no problem at all for my truck.

Replace that k&n intake right away. Those k&n intakes are no good for powerstrokes. I lot of people have learned that the hard way when their turbo and engine was destroyed and they had to replace everything. Get ais intake for $200 if you can afford it here.

I would check and make sure the ICP sensor didn't get unplugged. I would also get codes pulled ASAP to find out why this is happening.

Should not have caused these problems, I think you were the victim of coincedence.

You only need two tools: WD-40 and Duct Tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Sorry, I meant Coincidence

Coincidence - Wikipedia, the free encyclopedia

Two lines going out under similar circumstance, totally unrelated to each other, and making you think you have an underlying common problem that caused both malfunctions.

I think I pretty much covered your question.

Just random bad luck that's not really related.

I'd start off by not towing in a chip/tuner setting that is not recommended for towing. With 2 new lines off the HPOP you should be fine now.
