I have decided that all I need for my almost stock truck (injector upgrade before I got it) is a replacement aftermarket lift pump like a FASS or Raptor. I read some good and some bad about both.. Any opinions about which one would be the best way to go?I have a motor mounted pump on my 2001 and I am told I wouldn't need a draw straw. Would everyone agree with that?I also plan to put a big line kit all the way from the tank to the VP44 and a pre-filter before the pump.Thanks in advance for any opinions or advice.

I go from the tank to a single can filter/water separator - from that to the Raptor - from the Raptor to the stock filter - from the stock filter to the VP 444. I have removed the stock lift pump from the motor. My big line kit only goes from the draw straw to the stock filter. I left the stock lines on from the stock filter to the VP44. I am sure that hurts me a bit, but even when I am towing I take it very easy with this truck. If my temps get up to 1100 when I am climbing a hill while towing, I just grab a gear and back it down under a 1000. I try not to get much over 950 pulling a big hill. The guy a Vulcan said that not putting the big line kit from the stock filter to the VP44 wouldn't hurt with a basically stock set up like I have. But, I think next spring before I start towing again, I put the bigger line on all the way. Just to be on the safe side.Doing research is a good thing. I did that before I did mine. The guys on this site are the best. Everyone is always willing to help. I know I ask a bunch of questions that were very elementary and everyone was very helpful.Yes I have started running the 2 stroke oil. I could notice my pump didn't make as much noise after I started using it.

Thanks exactly what I was thinking on the old pump!!? As far as the 2 stoke oil goes that's exactly what I got. I made sure to get the same as Mopar1973Man was running since that's were I was informed of this idea. Sent from my iPhone using Tapatalk

Oh ok thanks again Utah Dually!! I was reading that wrong before involving the stock pump versus the stick filter ? speaking of elementary questions lol I have one of my own. I do not have a fuel pressure gage on my truck also something I'll be adding to the old girl anyways I need to test the fuel pressure. How do you use a Fuel pressure tester?? I know I know probably pretty elementary but like I said I'm very new to the Cummins! Sent from my iPhone using Tapatalk

Good question on the tester. Never used one. I bought my truck and put the three gauge pod on right away. That was one of the things everyone recommended doing first, so I that is what I did. The one thing that improved the performance on my truck more than anything was putting the 4" exhaust on. WOW what a difference.

Yea something else on my list of to do's in this truck. I've had mine about a year now went to Arizona and back to Mississippi towing a car did not have one issue. The only thing I've had to do to her is I recently replaced the starter contacts. I did put a K/N filter in her but thanks to Mopar1973Man's web site I'll be replacing it with a BHAF soon! The only reason I believe I need a lift pump is because I've always had trouble keeping her running after a fuel filter change. I all ways have to crack the injection lines to get the air out and then it's smooth sailing. Plus i don't her a pump running when I turn the key on but she always fires up?

A fuel gauge will take the guess work out of that....

Yea I think I'll just put the gauge on there instead of buying a tester save my self some $! Also I've here'd a mechanical gauge is better to go with what's your thought on this? Are they hard to install? Sent from my iPhone using Tapatalk

Everybody has their own preference when it come to mechanical vs electric. I like mechanical, but then I am an old fart, and have been using them for years. I got the ISSO three gauge set from Vulcan. The fuel gauge was a snap, but the pyro took some work. I took the turbo off just to make sure I wouldn't get any crap in it. Routing all that stuff up thru the A piller wasn't fun either. But I am too old to be standing on my head under a dash. LOL

Lol! Ok here's another elementary question lol I here people talking about pyro and Boost gauges but I seen were people talk about what is for? and the importance of keeping an eye on it with a gauge? Thanks for your help with my elementary questions lol. Sent from my iPhone using Tapatalk

I guess I would say a boost gauge is not really mandatory. I just like mine because I can keep an eye on how shes running. I also use it when I'm trying for mileage as well. I would say a pyro is necessary if you do any kind of towing or hauling. You want to keep an eye on those exhaust temps as much as possible. Don't want to melt your motor down just because you couldn't see how hot it was getting. Also, if you spring a boost leak or something isn't running right with the turbo, it will show on both the boost and pyro gauges. I also use the pyro for timing shutdown of the engine. You always want to let the EGT's cool down to about 300 degrees before shut down or its real hard on the turbo bearings.

Thanks for the great info!! Yea I all ways let mine idle for a minute or more depending on if I'm hauling or not before shut down. Sent from my iPhone using Tapatalk

Lots of questions asked here. I will throw my 2 cents in. #1 do you know that if you switch your ignition to start, (Just tap start but do not start), the fuel pump will run and pump for 20 seconds to prime the filter and flush all air out through the return. #2 I am pure stock, as you are and prefer the boost gauge over the pyro as being stock you will never overheat. Start boosting over stock, definitely get the pyro. #3 fuel pressure tap? Vulcan sells a banjo bolt for the vp44 that has a 1/8 inch pipe port on it to tap in a pressure gauge. #4 my system for a stock upgrade increases fuel flow by 250%. I cut off the stock 5/16 fuel line just out of the tank Slipped 3/8 fuel line onto it. From there went to a slip on fuel strainer can. From there to 3/8 slip to #12 jic fitting into the Raptor 100, out of the raptor through 3/8 fuel line to the stock filter using new 3/8 banjo fitting and continue on to vp with same 3/8 banjos. All banjo bolts are drilled out to same bore as the bore in the 3/8 banjos. 5/16 I think. (found the aftermarket 1/8in tapped banjo bolt was not large enough) You can buy after market banjo bolts with a larger bore. All after market parts bought from Vulcan performance.

First off oldbeek, thanks for the reply and info! yea I new to bump the starter to get the system to prime again, as far as your aftermarket lift pump system I'm pretty much doing the same thing as you only with 1/2 fuel line! Sent from my iPhone using Tapatalk
