After failing two FRC-10 lift pumps, I'd gone back to running the OEM pump for the last several months while I was deciding what to do next. I'd been leaning toward the FASS DRP 02 pump that seems to be a common Cummins upgrade. I just wasn't sure I was willing to spend $250 for a lift pump.

I finally pulled the trigger and the Summit box was waiting for me when I got home tonight.

This pump uses banjo fittings at the inlet and outlet. It comes with the banjo fittings, but does not include the banjo bolts. I picked up a couple M12x1.5 banjo bolts from my local Deere dealer. This was the cheapest place I could find the bolts. The Dodge dealer wanted over $8 each. I found part number FG6360032 from the Deere dealer for $2.19 each. Summit has them for around $6.

This pump should deliver 16 to 18 psi and around 64 gph. Hopefully this pressure won't be too high for the DS4.

The truck is up on ramps and the OEM pump is off. I'll start working on a mounting bracket tomorrow and try to get some more photos posted.

I got the bracket built this morning. Ended up repurposing the bracket I had built for the walbro - so it doesn't look quite right. Pump is mounted. Cut off the deutsch connector and put on weatherpack. Jumped the relay momentarily and the pump runs. Still need to hook up lines and tighten fittings. Stuck doing family stuff now. Will try to get back to it this afternoon.

Having trouble loading more than one photo at a time...

Ok. I'm back home on the computer now. My phone was trying to load all of the photos with the same file name. DP didn't like that and I couldn't figure out how to fix it. Here are the photos I was trying to post.

I did get the pump hooked up and running this afternoon. It pegged my low pressure/vacuum gauge when I checked the pressure at the T valve at idle. I decided this would be a great time to install my 30psi fuel pressure gauge. Should have been a simple job, but I ran into a couple problems:
1. The gauge sender would not fit in the location I had left myself when I did my FTB install.
2. The hose to the T valve was in very rough shape where it attached to the FFM and was leaking fuel into the valley.

I tried indexing my fittings differently to make more room for the sender, but eventually had to pull the FFM and put in different fittings. I think it will fit now, but I didn't get the FFM completely back in place yet to verify.

Luckily I had a piece of 1/4" fuel line in stock that I could use to replace the T valve hose. I struggled for a while getting the new hose to route under the intake, but it is in and attached.

Here is a string of crappy photos showing the pump in place and connected. I had a terrible time getting good photos. There is just too much stuff in the way when you try to get back far enough to show the system. I tried for quite a while and these were the best I could do. The pump is located in the same place as the original.

Looking at the photos, I see I still need to get some harness wrap on the fuel pump wires.

I probably won't be able to make much more progress until Wednesday.

nice, on my old 6.2 I had 3 stock lift pumps fail in less than 3 years.... of course advanced brand... I've been looking at doing something like this. I can't hardly use any trash national parts because they are all cutom fit crap...

Great write up.

What kind of fuel are you using?

Do you already have a reflashed PCM? Between higher fueling capability and that turbo upgrade you are looking at, you'll be happy to have the beefy LP.

Thanks!

#2 Diesel. Once in a while 5% bio. I have run some home heating oil that I got for free, but that was probably less than 50 gallons. In the winter I add Howes diesel treat and in the summer add some 2 stroke oil for lubricity.

Not yet. Waiting for you to start tuning OBD2!!:whistle:

Here's a photo of the bad hose to the T-valve. No surprise that this thing was leaking.

Think I'll notice anything? I couldn't tell the difference between the OEM pump and the FRC-10 when I made that switch. I know some guys really seem to notice, but I just couldn't tell. Certainly not like changing to the 4" exhaust anyway!!:coolnana:

nice work, I am wondering why they sent those hose fittings/connections with the pump, instead of threaded hose barbs (higher-flowing) ?. try cetane boost additive, it's like running old gasoline, then filling up with premium. a few ounces vastly improves fuel economy too.

FASS sells this pump as a kit intended to be a bolt in upgrade for a Cummins. It appears they tried to make the install as easy as they could for that application.

Tough to say for sure just yet. It is a gerotor pump so more of a whine noise than the OEM thumpa-thumpa-thumpa. I can't hear it with the engine running. Seems to maybe be about the same as OEM volume. I can let you know once I get everything back together.

Just a quick update:
I got the truck back together last night and drove it to work this morning. So far, this is what I've seen for fuel pressures.
Waiting for glow plugs: 18psi
Idling after first starting: 22psi
Cruising on freeway: 20psi
Hills on freeway: 19-20psi
Wot acceleration: 15-16psi

does the injection pump sound different with that much fuel pressure? also, does it behave differently?

Give me some time to evaluate. I haven't noticed any difference in the injection pump sound. There may be some behavior differences, but I'd like to drive it a bit more before commenting. I'd rather not make false comments.

1 Week Update

After driving it for a week, I've noticed no difference in the way the truck performs. I've been meaning to do a WOT run with the Gtech, to compare against old results, but I haven't made that happen yet.

The % load as displayed on my ultragauge is unchanged on the highway - So this pump isn't making the DS4 deliver any more fuel than what the controller knows about. WOT throttle feels pretty much the same.

The pump is pretty quiet. Probably slightly quieter than stock. I can hear it while waiting for the glow plugs, but I have to listen for it. If you are at all hard of hearing or if you aren't paying attention, you wouldn't hear it.

My fuel system should now be up to supplying everything the DS4 can do!
