Review on Fel Pro 72401 O Ring by Kevin Cheek

I noticed my 05 Avalanche had low oil pressure. After researching online, I found that the o-ring on the oil pick-up tube wears out quite often over time and causes low pressure (my truck has 201,000 miles). While the job turned out to be a bit more difficult than I first thought (the front diff runs right over the oil pan cover and had to be lowered to get to the cover), this turned out to be exactly my problem. Once I put everything back together I was happy to see that my oil pressure was back to normal.
