I have a carter 4601hp on my truck pushing through my stock lift pump. This pump is rated 14-16psi and 100gph. I have had it on my truck for almost 2 years now and i havent touched it since i put it on. It seems to be a well built pump. Its quiet and I can tell im getting more fuel in the higher RPM. It pulls more RPM and sounds smoother up top. This pump is about $123.

Carter P4601HP

I know that the Raptor fuel pumps have a lifetime warranty and come with a fuel line kit, etc. You can get them in either 100 or 150gph. The main thing i like about them is that they look fairly heavy built and are warrantied, but they are $400. That seems awful steep to me.

PureFlow Technologies Raptor RP-150 Fuel Pump (150 GPH)


I would like to eventually get rid of my stock lift pump and just use an electric pump pushing through the stock filter system. Would the carter handle the fuel my pump would need for 500hp and 4k RPM with no problems? What about the Raptor?

It just seems to me that I would be better off buying a kit with the filters for around $100 more than buying the raptor. I am also a fan of mechanical pumps, and i drive this truck every day so i have a hard time trusting just an electric pump on it. As of right now, If my carter dies, my stock pump will pull through it until i can get home or whatever. Or i can just bypass it. I think if i was going to just run an electric pump by itself. I would keep my carter and buy an extra to keep in the truck in case something happened.

I think Matt Wells was running 12's or 11's with just a holley blue on his 12v.

Im sure i will just keep running it how i have it for a while since i am having good luck with it so far, but I am just looking for suggestions and opinions on the matter.

Eric I've been running a raptor on my 97 for the past year since I won it in a drawing at Cedar City Diesel. I continued to daily drive the truck, and haul with it until I purchased another truck.

I would not hesitate to jump in my 97 and drive/tow with it after setting the suspension back to stock and putting an appropriate turbo back on it.

No problems here with a electric pump! ;)

If your interested though, I have a holley blue on my new 99 that I believe it pushing too much pressure to the VP (Juice says 30psi idle) I would make you a good deal on it since I'm planning on putting a raptor 100 on my 99 since its adjustable.
 
Im happy with my carter right now. It has been really reliable. From everything i have heard they are more reliable than the holley, but it seems people have luck out of both of them.

Sounds like just a raptor is plenty of fuel. Is it the 150 Mark?

Are there any advantages to bypassing the stock lift pump? Will the stock lift pump hurt the flow or volume of fuel that an electric pump is pushing?

My Raptor 150(sorry) is routed directly to my fuel filter canister. All AN fittings and 1/2 line @ tank, pump, and filter. You've seen my vid's from this year (Scottsville, Temple Hill) that's with the pump turn all the way up 28psi idle 30 with some RPM's.:evil I would remove the oem lift pump and go directly to the filter housing like CCD did with mine. Just buy a small block chevy block off plate at Auto Zone/Advance to close off the hole in the side of the block.
 
Yeah I may eventually do that. I just am leary that i will do it and then my carter or any electric pump would take a dump and I would be stuck somewhere or without my truck until i could get it replaced. Like i said though, so far my carter has been great.

I am curious to hear what people have to say about leaving the stock pump in the system though. Will it restrict flow any?

Speed Demon- I added the carter to my truck because it was sputtering at anything over 2800rpm under load even with a new stock lift pump and overflow valve. The carter took care of the problem. I know it will at least turn around 3500rpm now under load without sputtering with a clean fuel filter, but im wondering if an electric pump by itself would be better than running the mechanical pump with an electric one pushing through it.

ok, im not having any fuel problems not and it has a new mechanical lift pump. i would like to add a pusher to help keep the IP fed.

i have an Airdog FP-150 in my 6.0 setup to run standalone and it hasnt had any problems in over a year since its been on. once the cummins goes in the ford the airdog will run standalone for it as well.

And what about the fittings and things you will need also? And all the driving and searching for things? Time, fuel money, and cost of those fittings will bring you right up at that $400 mark. But without the lifetime warranty, 1/2" everything, and the adjustable regulator. Maybe I'm a little one sided but I think the Raptor would be the way to go.:hehe:
 
If it aint broke don't fix it. I know you use your truck now for DD and hauling and arent looking to get crazy horsepower out of it. I say stick with what you have now, and down the road when you turn it into a puller/dragracer then switch out the pump to an electric one or an A1000. But for right now, I would leave it alone

I was talking about buying a complete Air Dog for only $100 more than what the raptor runs. It comes with all that stuff, and the filters so i could go ahead and get rid of the stock filter setup.

I do just daily drive my truck right now. I know if i bought another truck to drive and made this one a strict pulling/racing truck that i just drove at times i would go with an electric pump setup.

cquestad- You wouldnt want to sell it for about 1/4 the price of a new one would you? :hehe:

Unless i run on a deal, i probably will stick with what i have for now since it is working pretty well. I just like to know my options.

You can build a filter setup for around $40 with the filter if you buy it all at a big truck supplier. Baldwin fb1311, two fittings for inlet and outlet they are a standard thread with oring fitting, m14x1.5 to pushlok inlet on p-pump, a tee for the return line, 2ft of rubber hose. That filter base is 1-14 thread pitch. There is all kinds of 2 micron filters that fit it.
 
Yeah, I was thinking about If I got a raptor that I would build my own filter setup on the frame rail with a simple filter base and fairly standard filter of some kind, and get rid of the stock filter setup. I wouldnt mind to do that.

Im waiting to hear back from Cquestad, but if his is priced right, I will probably buy it and work on getting it on pretty soon.
