dual fuelers question

RSK · Apr 28, 2015

how many guys are daily driving their trucks with dual k16s and how many miles per year, also what low pressure lift pump are you running. I have my 7.3 I could use for work if i had to to but i really prefer to drive the 6.4 if possible. I've heard a lot of local rumors that reliability goes down hill quick once dual fuelers and nozzles are added to a 6.4. I'd like to continue driving my 6.4 about 30,000 miles a year. I was thinking of doing an a1000 low pressure fuel system from marty's diesel or something similar.

Lots and I mean lots of guys run duals for daily driving. Shane has probably 40-50,000miles on his. What seems more logical? Running a single at 90-100% or running dials at 45-50% at full power?

Agreed! I daily mine as well.

it was talked about, once upon a time, where using a used pump as the dual fueler was actually a bad thing, because when you reversed the rotation it was detrimental to the pump, thus causing premature failure.

something to consider when deciding on your second pump.

are you asking about running them without anything else OR with the other usual big mods ?

Personally, I went with a lower mile original siemens k16.
Seems like remanufactured pumps out there are a crap shoot IMO.
I had heard Alliant Power was was supposed to come out with a better pump, but I don't know when that is.

the fact you are running dual fuelers doesnt change reliability much...its what you do with the new found power and what big air mods you add that changes it.

I daily drive mine pretty much spring till end of the fall. I put 8-9k miles on the truck last year, driving 1900 mile round trip to TS and 1300 mile round trip to Rudys. I also used a 40k mile used pump as my secondary. No issues so far. Only preventative measure I use is I carry a spare belt in the truck in case something happens, and it's a belt that the local napa doesn't normally stock.

I think for the most part the issues you run into are with the added power, not actually putting the pump on.

I agree running duals at 45-50% duty cycle seems like it would be a lot more reliable. The low pressure lift pump is most likely a bigger issue. Also all these "new" k16's leaking doesn't sound too appeaing, so i was going to go with an oem used pump up front and my original k16 in the factory location.

90% percent of my driving is done at 25% throttle or less. The other 10% is over half throttle and a weekly wide open throttle pull getting onto the highway.
