Correct, I can't get any black smoke, even when passing someone. I have the raptor frrp, and a big line relocation kit. Other than those mods my truck is completely stock. Maybe why I can't get smoke:think:

Awesome:hyper: thanks for the quick replies!!!

Hi guys,I've just noticed this black puff when starting the truck. I have no idea how long its been doing this. I bought the truck in November 2012 with 306000 miles knowing it would have some problems. So it could have been doing this since I bought it . My question...Is this normal, or something that I should be getting concerned about? This is the only time is blows the black smoke. Never going down the road, even when I get on it really good. I'm trying to embed a video of what the truck is doing. The smoke looks white because its coming right at the camera, but it is black.

Checked connections and then re-bled system. Same thing. I was extremely low on fuel so I thought it may be sucking a little air from the tank. Went and filled up Sunday and no problems so far. I tend to overlook the simple solutions:banghead:

I will try and re-bleed system tomorrow. I did not have the issue any more today. Is it possible that the air worked its way out of the system? There are no quick connect fittings on current setup. Thanks for the replies.

I installed a big line kit last night. Now i have 3/8 line from original hard fuel line to relocated lift pump (raptor frrp) then 1/2 line to original fuel filter canister, then 1/2 to ip. The pressures look better 17 idle, 15-16 cruising, 12 WOT. Truck ran good this morning for a 30 mile trip. The problem is that the idle is a little rough now. Never like it is going to shut off, more like a hiccup. Did the same thing last night after I started it. I thought maybe some air still in the fuel line???? It did not do this before the relocation install. Any ideas? 2002 ram 2500 5.9 cummins

Got big line from filter to vp44 with fuel pressure gauge.Idle - 17psi (in gear 17.5-18???)Cruising 55-70mph - 14-15psiWOT - 10psiWOT seems a little low to me, but are these numbers acceptable? I'm hoping they are ok, but if not, I'm considering the relocation kit. I've read the relocation kit is pretty straight froward. Cut supply line and run 3/8 to relocated pump, run 1/2 from pump to filter housing, then run wring harness. Anything else I'm not thinking about? Would you guys recommend the 1/2 or 3/8 relocation line (pump to filter). Just curious since i'm stock and running raptor 100.Thanks again!!!!!

That is correct. Stock lines from tank to raptor pump in the stock lift pump location, 1/2" line from raptor to stock fuel filter canister (1/2" line came with raptor), then stock line from filter canister to VP44. I believe the raptor is rated for 100 gph, but not sure if t could do that with stock fuel lines from the tank.

Thanks for all of the insight!!! I feel like I've done more research on this VP44 than I did in four years of college . I will get that kit and add it on ASAP. I'm currently checking pressure through an isolator and I'm not real sure about the accuracy. As soon as I get the big line kit i'm going to ditch that thing and go with the needle valve set up.Strange thing is that when the VP44 was replaced the truck was still struggling to run and throwing a P0230. The mechanic called the pump shop and they told him to turn the Raptor down to 10 PSI. Since then there has been no code or any problem (noticeable) from the truck. The pressure has been a concern for me though. Hopefully the big line kit and getting the pressure up a little will solve the mystery for me

Sorry. Should've given more detail. 12.5 at idle (I know that needs to come up)10 cruising7 at WOTi was also referring to the Vulcan kit from filter housing to pump.

Hi guys, New VP44 installed a week ago. I also have the raptor 100 mounted in the stock location with stork fuel lines. The pressure is dropping about 4-5 psi at wot and about 1.5-2 psi at cruising speed. I'm trying to avoid another vp44 replacement.....ever :banghead:. Would a vulcan big line kit be beneficial to me to help keep the pressure up? Thanks in advance for all replies, and thanks for the wealth of knowledge on this site. 2002 Ram 25005.9 Cummins
