Need mechanical pump for belt drive setup.

I too was at the point of going to a belt driven pump after burning up 4 brushed fuel pumps back to back. I actually own a complete Aeromotive belt pump with universal mounting hardware and a couple pulleys I was going to use.

However, luckily, before I got too far in, I found the Fuelab Prodigy pump. It is a BRUSHLESS electric pump. The pumps themselves are never the problem, it's the brushes in the motors that go IMO, and experience.

Fuelab makes brushless electric pumps that will support more fuel flow than anything any of us could ever consume.


This is the one I've been running for the past few years:

A 1000cc p-pump will consume 5GPM, not to mention needing 30-40% additional fuel for cooling. The biggest fuel lab I saw was a 200GPH?

So double up...


Although how many guys need to support a 1000cc pump in a daily driver? Zero?

And fwiw, right or wrong, I was under the impression all along that this guy was going to be driving the truck on the street a decent amount. I doubt 1000cc pumps are the norm for most people in that situation. So I suggested a damn good electric unit that will last.

And furthermore...

I assume that a 1000cc pump injects 1000mm^3 each event at full governor? If so, and we assume an engine operating speed of 6000rpm, then it would be consuming 3.6gpm, or 216gph. And that is a competitive pump, running full displacement at 6000rpm. 7000rpm would be 4.2gpm or 252gph.

Now how likely is it that anything but a dedicated truck would be consuming/burning that amount of fuel at 7000rpm?

I wouldn't expect to run across something like that in the Wendy's drive-through line, that's for sure.

Just a FYI, the Aero belt drive pumps work for diesel. Just like the A1000 pumps are not diesel rated but work just fine. I am under driving the pump at 50% engine speed and it makes 20 psi. while cranking. Holds rock steady at 50psi. but no wide open runs yet. Factory fan and a fluid damper even fit in my swap with it.

Nicely placed.

That's the exact same pump I've got sitting in a box in the barn. Same pulleys it looks like too. I was going to go 50% under myself.
 
Thanks.

It is a modded MITUSA mount on the oil pan. The pulley on it came with the pump kit so it's most likely the same one. I used this belt drive because it was one of the few I found that worked without an electric pump to prime it. 1 thing I did find is that a 6an return was not enough. Pressure would creep up at speed. I changed it to a 8an line and it works well so far. If higher rpm's cause issues I may under drive it even more.

Two in parallel should work. OP normally doesn't do anything too sane, I wouldn't put it past him to drive this truck on the street everyday. Does FuelLab have a pressure/flow graph for 12volts or 14v for their big pump? I'm curious to see what it does at 50psi & 12v.
 
Waterman, Weldon, DSR and Ron's all have billet pumps that are built to closer tolerances and should fluctuate less than Enderle or Hilborn cast pumps.
 
For $200 with a bypass valve, bracket, hose, and pulleys. I think it will work.

I just need to figure out a drive ratio.....yay
