viper700,
I considered having the in-tank pump installed under warranty, however decided against it. The thought of using a pump that puts out low pressure (around 9psi from what I've heard) isn't very comforting. Therefore, I opted to eat the cost myself before I let the dealer give me a pump that barely meets stock fueling requirements. At this point, I only have the Van Aaken 3. 1, but want to install injectors at a future date... probably after warranty elapses. Too, right now, the pump is working properly (sounds like it anyway, no fuel gauge to verify). Therefore, the dealer, despite P0628 code, will just give me a song and dance, deny the warranty claim, and charge me a hour's labor to boot.
I went round-and-round with dealer about a lift pump failure on my 2001 (had gauges installed to verify low pressure) They are required to perform a volume test, not pressure... just won't put myself through it again. I replaced the pump at my own expense then also. I just don't want something to fail when I need it the most.
My wife was with me when the pump acted up and the truck stalled. She said to spend what it takes to make the fuel system reliable... ordered the GFS-392, big line kit, and strainer today. Now, if I can just convince her I need gauges to ensure I don't have a piston meltdown, or grenade a turbo, I'll have it made! Just don't want it to happen before she's convinced.
I'll let everyone know the outcome of the kit install. Take care.
