Do they make them, what sort of hp can it support, are they a good upgrade, are they even worth it. I am looking for a good upgrade from my stock diaphragm LP. I have also been considering a P-LP but I was told that the pressure would push the front seal right out of my IP. Any info would be greatly appreciated.

 

You can get a low pressure Piston pump, or you can get a regulator and run the 2nd gen piston pump.

I'm not sure about the Airdog though.

 

Who sells the reg. and where does it mount?? Sorry for all the noob questions. Just trying to learn so I can be one of the smart guys one day.

 

There are several regulator options, and you can mount the thing anywhere you care to run the hoses. The important thing is that you use a bypass regulator and that it is plumbed AFTER the fuel filter.

If you go with the Air Dog, do not run it through the stock fuel filter. Run it straight into the injection pump.

 

What would I need to install the kit or does it include everything. And what would a kit for my truck cost. Aslo, do I block off the stock LP Port or keep it open?? So many questions.. Thanks for all the help..

 

Sorry for hi-jacking...

I was in the understanding that piston style fuel pumps didnt need a bypass reg, and they worked better with a dead head...?

I understand the after the fuel filter part, but could somebody clarify the deadhead vs bypass reg thing?
Thanks...

 

2ND GEN Lps put out WAY too much pressure for the front seal of the VE. Put a regulator after the filter then you have the benefit of high pressure and flow through the filter then bypass what you don't need back to the tank to keep the VE happy.

 

Doesnt the VE pump have a bypass line?
Cant you regulate the high pressure pump to 15 psi after the filter with a deadhead instead of running 2 return lines?

 

Bump....
Need more characters

 

where can this be purchased? Part number? Cost?

 

If you can find one with good enough flow I guess you could run a non-return regulator.

 

wanna,

why wouldn't you run the fuel filter if using the air dog.. Does it have a filtration system built in.. What is the better mod, auxiliary pump or the low pressure lp?

 

Yes, the Air Dog has a primary filter/separator and a good secondary filter on the unit. The factory 1st gen filter would be a useless restriction.

It really depends on how much you hate electricity.

I like piston pumps for trucks under 350 HP, it's simple, it's reliable, and it's enough fuel.

 

I am currently on the prowl fer a Air Dog setup. I just installed some 6x18's and keep running out of fuel. On a hard run it'l drop to about 5 psi.
