So I have the kennedy dual's. What if I threw another one in there and made it a triple? Would that work? Because he says in his little description things, that if you do one you get like 8 psi, and if you do two you get like 12 psi (I dont remember the exact numbers but you get the idea). So if I put another on there would I get 16 PSI?
Just Thinking out loud
- Thread starter Smokin LB7
- Start date
I have wondered the same thing but for my SuperDiesel Carter single setup....with a full tank of fuel i see 8psi, with less than a 1/4 tank i see more like 4 psi. I have a LBZ pump currently that is supposed to be able to see more pressure at the inlet than a LB7 pump. so could I add another Carter or 2 to feed more....safely?
Still have to go thru the FICM on LB7/LLY, LBZs don't have them. You could push 100psi to the CP3 if you wanted to but would have to route around the FICM or amplify pressure after it like the MITUSA.
So would the short answer be no? Or it would work if I did routed past the FICM (and by the way that is the Fuel Injection Control Module correct?)?
You could run another one off of hobbs switch to come in at a set boost when the other 2 get drawn down at WOT. Would have to run a regulator before the FICM to keep it from exceeding 12psi.
Why not just run one pump that is higher pressure? If you want to go really high pressure get a boost indexed regulator to go with it. If you want it all in one pre-engineered kit talk to Wicked Diesel.
why not just put a small lift pump and just run fuel through FICM just to keep it cool and run a higher psi lift pump to the cp3 couldnt this work just a thought
I am pegging my 15psi gauge at idle and low RPM on my LB7 and its still going through the FICM. So it could be higher than 15psi easily. IIRC lowest pressure i get was 7-8 psi @ WOT. Love this pump! The FICM did start leaking but i pulled it out and found the case screws were loose, so i tightened them and has been all good! I had heard from some that over 10psi the FICM gets cranky and makes a funny idle. Mine does this but it could be my modded FCA causing this? So ultimatly, one of many small test/projects im wanting to do here soon is a separated FICM cooling system. This way, the FICM dosent heat the fuel more, can run plenty of PSI to the CP3. Eric Merchant did tell me that too much CP3 inlet psi could blow out the front seal of it, so be mindful? That would be a quick ticket to a crankcase full of diesel!
I dont see how it could effect it? LLY ficm has a 3/8"ID pipe cast into the ficm case, Nothing is connected or comunicates with the wire or computer board
maybe the wifes tale is from a lb7

pushing the lil spring on the regulator open
I think its the FCA and the high psi exacerbates it somewhat to. Thinkin LLY and LB7 FICM's must be fairly diff beeings mine leaked and tightening the case screws stopped it. Dosent really bother me, could care less, long as it dosent strand me. Like i said, a separate cooling sys. for it is in order along with some other small mods here soon!
i run 14 psi to the cp3. my tap is inbetween the pem filter and cp3 so i know how much psi its gettin.
my ficm looks fine. i might turn it down a bit to maybe 10 or 8psi to the cp3.

I don't want a MITUSA because it takes up pulley room if i ever do a dual CP3. I also was wondering if there is a way to eliminate the FICM on an LB7? and if not, i would simply run my lift pump outlet line all the way to post-oem filter?
hmm..that's alot of pulley....eh, i still think the second lift pump might be easier anyways but for shits and giggles: how much $ is a MITUSA?
