I am digging that Cat 1R-750 filter!!!! Do you also run a filter in the 6.0 housing

Yes as I don't think it will run properly without one. My notion at the time was that more filters where better then less and with the P55800 as the first defence in ridding big chunks o' keerap and water with iirc 20 microns and the Cat following the 6.0 one I'd be good. BTW the Cat and Donaldson are same thread size heads and common, I keep a spare set with me...

In draining the P558000 and pulling the water plug on the 6.0 pump have yet to catch any water in it.

whats the gph on the 6.0 pump?

Ya know lincoln...I don't recall, I will probably only run 160s with maybe 100% nozzles (have to rebuild a spare set of Baby Swamps first), which is next up on the list after steering ram.... This pump will handle that as the 6.0 guys are running larger injectors with no problems is my understanding.

For me the integrated E-heater and internal fuel by pass features of the early 6.0 HFCM style pumps is of interest. The internal by pass monitors fuel temps and when input fuel is 50 degrees (iirc) or colder, the by pass routes (warm) return fuel, back into the delivery fuel stream rather then sending back to the tank.

Again I have not hooked up the power to the heater, was waiting until I had the 200 amp Leece-Neville alternator done, (which is done now :D)..... so hopefully by this fall will have it dialed...

That is a cool feature on the by pass. Kinda makes me wish I would have looked harder at it.

Thanks guys,

On my now parked 96 parts truck I ran tha SD E-pump for thousands of kms and in some very cool winter weather (-35 C) never had a one problem and I got the pump from the wreckers too...

On that system I put on an inline veggie heater but never put the power to it. Winter fuels being what they are now days not sure if you really need a heater. The later 6.0 HFCM didn't come with an interaged heat.... Do the newer SD's have em? I looked at a 6.4 pump a while back and it didn't iirc have one and the hard lines on it where a larger in dia then my pump.

How small of primary are we talking , as of now I have a Napa water separator, pump then 2 micron Donaldson. It's been on about 45 minutes . Soon to be swapped with cat filters

I will be running a very similar set-up with a 392 on my OBS here shortly, just gotta get time to finish building it all and install it. One thing that worries me is pump life, but i was tired of trying to find decent used SD pumps so figured i'd spend $115 on a new pump.

where the antelope play
Are the fittings for the bosch 44 and the walbro the same ones? Im on my 2nd walbro and I think when it dies I will get a bosch

The fittings I got with mine were 10m straight thread x 3/8 barbed... I found out today that braided 3/8 line will NOT fit on 3/8 barbed .. not enough stretch. Buddy took a lathe to em and problem solved

You can get fittings that go from the straight thread to AN-6, 8 and 10.

No, they're different. You will also need to install a check valve as the pump does not have one internally. I think beans can source the parts for you.

I first built my system with a Walbro and it worked fine for 4yrs then died. Got two more and neither lasted more than 3000 miles :doh: :mad: I got a genuine Bosch SD pump and all is good again :thumbup:- go with the SD pump.

Were you getting them from the same source? There were a bunch of counterfeit ones on the market back in the 2006 time frame and continue to be.
