AIRDOG + IDI ANYONE?

[idiabuse]

Its like buying the largest possible cam for a Small block chevy, and putting it into a stock motor.

Can it be done, sure. Will it work, sure. Is it the right choice, nope.

We dont require that GPH or PSI. If you want to buy it, go ahead.

Most IDI owners own them as they are inexpensive, they dont want to spend a ton of money on a Airdog, when a stock lift pump, or a cheap electric pump works fine.

I dont want to ever feel my engine surge with power from air going into my IP.
whenever I feel the surge I know my IP is not getting proper lubricant, wich takes life away from my IP.

the extra volume of fuel I get from an AIRDOG will help me pull a heavy load without fear of overheating my IP.

If you put the big cam in a stock chevy it will work great! IN PARK.
put it in gear and it dont work at all!

we dont all have that kind of budget but we sure like to watch people try new things. i would enjoy seeing the results.

I dont like to follow the path well traveled just cause everyone else did it already.

Maybe the pump is not a bad idea, but if it spits air into my truck engine like my blue pump does I would be just a little pissed and money/time/labor short of an AIRDOG?

I think you would be the only person I know of to use a SD pump on a IDI so you would be on a road less traveled. As for air, not really an issue w the SD pump. they are a quality unit. but if you want to spend twice what a SD pump would cost..... its your money

Exactly. They are reliable and relatively inexpensive to maintain. No offense, but if you want to throw money around, why not buy a powerstroke? Slap in a chip and you have most IDI's beat.

Also, when did fabricating parts for a truck engine series that had little to NO aftermarket support become "redneck"? If you want to do ANY kind of conversion, you have to make it yourself.
Redneck is putting stacks on a station wagon, not putting a new style fuel pump in an older truck.

i dont like how everyone is saying redneck like it is a bad thing... i think i can claim that title and it is not a derogatory term in my opinion but i understand his frustration, i have been through 3 holley pumps in the last 3 years and i have had the same problem with all of them. as soon as money permits i will be trying a FASS. IMHO controlled overkill is the best way to go

 

[Diesel_brad]

The problem with the holly pumps as i understand it is they are not designed for diesel and it ruins them

 

[FordGuy100]

I saw a few 6.5 guys running dual Carter pumps, I think that would be a great route to go with.

 

[dsltech83]

dual as in parallel or in series??

AirDogII with a fuel pressure spring from a Duramax will keep 8psi all day. I was a Young Man in the 80s and the saying was Nothing Exceeds Like Excess. So on Wed. I bring my Truck Home and start plumbing and wiring and install my AirDog. I have not figured out the fuel selection valve thing as of yet but am looking at diesel switiching valve for marine use. Do I have to have it no. I want it !! with all of the other changes I have done this fuel system is just a bit of overkill but it will supply a moose pump and injectors in style and filter fuel perfectly in the process .

@Diesel_brad-
-Yeah, Ive been wondering about that... Is it a viscosity issue or chemical? Gasoline is is higher on the solvent scale, but is that the problem?

@tractorman86-
So far (knock on wood) my Holley Red has performed flawlessly for about a year now with an unregulated pressure that is not exact, but is right in the ballpark of the OEM mechanical lift pump.

@idiabuse
Air in your supply can only get there from the low pressure side of the pump (obviously), so do you have a filter between the FSV and pump? Is it clogged? Are the fittings and connections sealed/tight upstream from the pump? Tank metal pickup tube/plastic tube interface? When I get a "power surge" it just means that it's time to switch tanks 'cause this one's empty...

I'm not a cheapskate, but I am economically minded and want the best performance/dependability I can get for a reasonable amount of money. I have been eyeballing a miniature diesel specific pump at Advance-Discount
($36) for an emergency spare. Anyone have any experience with these, good or bad?

Ok, so the fuel line from the fuel selector valve gets split up into two lines, that way both pumps can get fuel. Pump number one is hot all the time. Up on the IP a trigger switch is engaged at any throttle input of your choice, I said 2/3. That way, if your cruising along at 1/3 throttle, your using one pump. But if you go WOT, it will engage the second pump, which will pump along with the first pump. Now both pumps need to be regulated to a certain PSI to work, and they both have to be the same. Then the lines go back into a block to go back to a single line, that goes to the filter, and onto the IP. Here is my rough diagram:

This would help address the issue of fuel inlet pressure dropping under WOT applications.

PARK....what the #$)% is PARK....that's a place u picnic...real vehicles use long sticks to stir the gears manually which has no provisions for a PARK

Ya ha...controlled overkill...I like that nicely coined phrase btw

Hmmm...how to run dual tanks with 1 FASS

 

[FordGuy100]

FASS airdog setup: $350

Two Carter pumps: $200

If one carter pump fails in my model, you can always have a switch in the cab to activate the secondary pump to run as the normal pump.
