If my new pump lasts the usual 40-50K or so, I should have plenty of time to get guages in and monitor the fuel pressure.
For a couple of reasons. Save battery life when changing fuel filters or for some reason the truck was run out of fuel. Extend lift pump life. No problem with low pressure to injection pump and maybe a few other reasons I'm forgetting .
the fass is great, I have installed about 20 of them and love the product. From the moment the motor fires you can tell a difference. Mike www.DunksPerformance.com
What's up with this RASP system I read about in another thread ? Anyone got any other info ? Thanks , Tom
