I have looked in the forms and searched however I cant find the direct answer to this question. I dont have any gauges on my truck at this time (fuel pressure, trans temp ect..) I am looking to get the quadzilla iquad bt so I can have gauges and a mpg tune. I have a stock truck expect a bhaf and 4 inch exhaust. I am not going to race or pull crazy weights. I just want a good clean running, efficient truck.  Should I get the quadzilla first or fuel pump??  Thanks for any advice.  

lift pump always as your lift pump is pro no putting out anywhere near acceptible pressure.

Alright thanks! 

look into fuel boss mechanical pump. wont fail like electrics and the psi increases with rpm of engine. same price less headaches.

That would be my next choice whenever my fass fails, but according to fass I should have it till I retire as much as I drive the truck. 

Like myself, I'm the odd duck here with an AirDog 150 went 13 years on the first pump and just replaced the pump head for the first time and still going running towards 300k miles on the AirDog 150 and got 353k miles on the truck.

I did not have the lucky Mike did with my AD 165. The first pump motor went at 7 years and 175k miles but nothing lasts forever and AD warrantied the pump no questions asked. Ala in all I am still happy with it.

Looks like I'll do Lift pump first. Or if I can sell this tractor I'll do both. Thanks for all the input guys! I appreciate it!

Make sure you use TCW-3 two stroke oil as well

thats cool they warrantied them, but still left you both down for a period of time till replacement arrived.  got to admit if the fuel boss fails its gonna be the belt which is $15 and 10 miuntes to change on the roadside. if it fails otherwise there are serious issues.

12 years mean time between failures isn't bad either. Most likely longer period of time for the AirDog between failures than on Fuel Boss. I don't think a belt will last that long for 250k miles and 12 years. My downtime was about 4 days. No worse than the down for other failures and ordering part like injectors or injection pump. So when I lost my VP44 after 243k miles it still was down 7 days waiting for parts and get it back on the road. Like injectors still got to wait for new injectors to get here still 3-4 day wait time. So down time to me is meaningless. It will happen.

The down time sucked but could happen to either i would think, though belt failure woild be simple to fix providing you have a spare.

Are you getting 7x10, I just drove my truck today after all the valve train stuff and a set of 7x10 vco set at 320, man I love it. Responsive, not much more smoke on my same dd tune and it goes now like it's wireing tapped but I'm on level 3. Egts seem to be down and engine load too, I know it's because of duration but still. I only put few miles on but so far I love it.

i have two in the bed box lol

 

the belt itself is loose on the pulleys so wear is minimal (very little stretch) it would take foreign object breaking it to fail otherwise

If my Fuel Boss ever fails for any reason (belt, pump failure, etc) my factory lift pump takes over and I get a warning light and I'm never left on the side of the road.

Your a rare one of the fuel boss guys never install the check valves and the stock priming pump.

I didn't install a backup because I had the in-tank retrofit, which was replaced with a Draw Straw 5, and I can't put a stock on-block pump back on for a couple reasons, and I have too much plumbing as it is.  But belt replacement is 10 minutes tops with a 15mm wrench... So I'm not worried about not having a backup.  Plus, the lugs on the belt itself are WAY over sized for the application.  I'm not worried about anything getting to it, and I've had it on plenty of forestry roads with no issue.

In tank pump here too.  I went the tank sump route and have my send and return at the sump.

Remember if you return to the basket or sump your pushing hot return fuel closest to the suction of the lift pump.

Got any information on fuel heating?

Yeah, the more you move it, the more it heats!  If you get diesel too hot (and WAY hotter than a lift pump or VP ever could), you'll get black gunk breaking out of the fuel. I forget what that is called.
