Opie.....how difficult was the installation? I spoke to Stefan the other day and a plumbing kit should be availiable sometime this week which should take care of some of the concerns some people are having.

 

I fabricated the entire line system on my truck that has two carters mounted on the frame rail in about 3hrs. The wiring took a little bit more time, but with my whole system it took about 5 1/2 hrs total.

 

CDRAM, which 2 CARTERS are you running? I am using the 4601HP in the stock LP location. I am thinking of adding me a filter base on the frame rail with an additional 4601HP. what do you think? If I could get the 18 psi out of the 4601 that it is supposed to put out, I would be happy with that. I am only getting 13.5. I just put a new on sunday. It is worse than the one I took off.

 

I did mine on a Sat morning and wasn't timing myself. My fuel system was already in steel braid line when KO sent me the RASP. Being in somewhat of a packrat (racing) community I already had most of the fittings. A kit would of been nice but in my scenario... I always seem to make my own kit as I go.

Bighead,
Running two 4601's in series is basically going to double your pressure. I have ran my truck like that but it seemed like once a year I still lost a pump. Also sometimes I would experience hard starting, like after getting fuel on a long trips. The cure would be to give it a little accelerator pedal when cranking.
