Most questions here are to fix a problem - or - "Why is it broken?" I want to know "Why is it fixed?" <img src="/forums/images/graemlins/lol.gif" alt="" />

Ever since I installed my present engine, I have occasionally gotten a whiff of gasoline vapor, but I've never found a leak. Lately, the engine has run a little ragged at times when it was cold - seemingly lean - but after a few seconds of power, it smoothed out, so I didn't worry about retuning it yet.

Last week, I changed the oil and while the engine was running, gave a look 'round the engine bay for any potential problems and found this:



After my shock that the gauge was pegged and the thought that I was probably washing the cylinders with gasoline and ruining the engine, I calmed down and realized that it wouldn't be running at all with that much fuel pressure. Besides, I had just changed the oil and it didn't smell gassy. So, I accepted that the gauge had blown and ordered another one from Summit.

The new gauge arrived a few days ago and I installed it Thursday - all is fine....... finer than I figured it would be. <img src="/forums/images/graemlins/scared.gif" alt="" />

Some of you will remember that I have been complaining about the torque converter lockup that makes the truck bog in O/D at low rpm with seemingly not enough engine torque to easily pull out of the hole in O/D around 1800rpm without downshifting. That is no longer true - nor is the ragged running when cold as bad as it was. The transmission now shifts when I expect it to shift and there is smooth power all across the band. <img src="/forums/images/graemlins/confused.gif" alt="" />

I guess I shouldn't complain, but I'd sure like to understand what has happened. I can't detect a leak in the old gauge in either direction. The weather is a bit warmer, but I don't think that has anything to do with it. Something magical has happened and I haven't yet figured it out.

Any SWAG is welcomed. <img src="/forums/images/graemlins/lol.gif" alt="" />
