Everyone,

 

My truck injection pump died, P0216, now what...

Buy an injection pump and re place or have someone do it 

I would have to agree with the above.

Long time no see @stodg73 ...

 

Yea, That is your only option is to finally replace that Vp44.

Well....

 

 

The options are:

 

HRVP

 

HOVP

 

SOVP

 

PP

 

Lets vote, however I get the final say...

 

 

 

MM, I have been lurking since my truck went down, and reading about the swap/replacement of the VP...

I vote HO since you have the HO engine. Unless you have some other things in mind.

U want ultimate power p pump u want ultimate reliability p pump with stock ish settings but it's a lot of time And money to make everything work like it (should) and I mean everything so vp is the way to go other then that unless u like power go hot rod hovp from everything I've seen is pointless

Personally I'm leaning towards ho pump if mine ever goes. I know so is more capable of top end but I have ho pump now and pretty happy with power. I guess it would come down to you choosing what you need. 2 pumps would be better though to experiment and have a spear.

Personally if its a daily driver just replace with a stock HO pump. 

 

If you are going to the race track then I would go p-pump. Even then there is guys that past the 1,000 HP barrier with VP44 pumps. Still have way better timing control with VP44 than a p-pump. Even though the p-pump can fuel more. The VP44 has way better daily characteristics and can be fuel managed way better now with the Quadzilla compared to Edge Products.

I’ve had HO and SO pumps back to back. Definitely lost a little bit of low end feel with the SO pump. 

 

P7100 can be swapped in for anywhere from $1500 to $5000, and requires cam removal. I’ve seen p24 valves that run very well with p pumps, and some that run like garbage. Depends on how well you set it up. 

 

Hot rod VP pumps are known for shorter service life over a SO pump, and a SO pump will make the same amount of maximum power (~750)

 

My vote is to stay with the HO VP. That’s what you’re used to and the truck won’t feel any different. 

 

Finally, I’m also in Colorado and willing to offer advice/help if wanted

Only thing to add to @trreed post is all the guys I've ever talked to after doing a P-pump swap typically take a hit to MPG's. This why I don't suggest it for daily driver setup. Again all depends on how you set it up and how much time you willing to tinker with timing and fueling setups. Normally the p-pump is for guys looking for big HP numbers.
 

aint broke dont fix it is my vote.  Replace the HO with an HO if you are happy with what it was.  If you want more than 500 hp then SO pump, if you want more than 650 hp then PPump

Well, I am wanting extreme reliability, ease of maintenance, and don't want to have to mess with it ever again.  Due to going places that are far from help.

 

Not worried about MPG, as I have propane to help.  I want about 250 how and 500 ft/lb of torque, don't want to do the transmission yet, when. That comes, I am wanting a 13 speed...

Stay stock...

The stock numbers are 245/505, and the NV5600 is the weak spot with the rear bushing.  So that is why I don't want to do any high numbers, I want to stay as stock as possible.

Well my nv5600 is holding up to roughly 650 hp/1400 tq, and has been for a while now so I would argue the rear bushing being a weak point. 

 

Woth proper fuel pressure and maintenance, a VP can last for a quarter of a million miles. @Mopar1973Man and @dripley come to mind with high mileage VPs. A p7100 can leave you stranded just as easlily as a VP.  

 

As for not messing with it, a p pump swap will take hours of your time tinkering with it to get the timing and AFC set up, and if you use a stock gear, you run the risk of timing slipping because it’s not keyed

243k miles on my last VP44. 

 

@dripley is going to beat me on the VP44 lifespan.

...and they said the NV4500 had weak input shafts and 5th gear nut problems. Never had any issues with either. I proved them wrong when I broke the mainshaft in half at the 3rd/4th gear syncros with nothing more than Edge Comp and +50 HP injectors. I tend to take most of this transmission weakness as rumor now.

 

 

As for all the transmission fears I don't buy into them at all. 

 

Now I'm running +75 HP injectors and Quadzilla which is way more power than Edge Comp and +50 HP.

I am closing in on you at just under 240k on mine. Boght mine when i was on the dark side of the moon.

My original VP lasted 250,457 miles! Replaced with a SO about a year ago.

Truck died while driving at 45 mph rolling along in 5th gear......and was able to get started on the the third try to drive the remainder of the trip home for about 4-5 miles. Engine would only rev to 1100 RPM and was able to short shift up to third without lugging.  Thanks to a kind Town Marshall escort I was able to travel safely at 10-11 mph for the few miles to limp home!

So more accurately; the original VP 44 lasted 250,452 miles! Removed the pump at the 250,457 miles listed above.
