Bought and installed my FASS in March of 04 and last week I lost all fuel pressure. Got out to listen and no pump running. Called Rip and he said they were offering an upgrade. I'm not to happy with this product that was suppose to last 500,000 miles or more and relieve me of any fuel pressure worries. Thank god I had a pressure gauge. The brushes in the motor were hanging up which could be fixed if the caps covering the brushes had not broken down to a powderlike substance. I have no gripe with Rip as he was great about dealing with DPP and I had the replacement in 3 days. I could have stayed with the stock pump at a fraction of the cost and still carried a spare. Live and learn. DW
