Installing an Electric pump to assist the Ip

[PeeBee]

@mudski is probably a good starting point regards the config I would think. He sells a wide range of filtration gear and knows the detail better than most. Drop him a PM if he doesn't chime in.

My set as follows. 2 tanks (147L main and 70L aux). I pump from the aux belly tank to the main using a manually activated in line pump. The aux pump is protected using a simple ryco inline unit that gets swapped out every 5000klm. I was under the truck yesterday and noticed its collected some crap just from the aux, so it will get changed soon. The fuel fills the main tank and I just use the dash gauge for level control. Fuel leaving the main tank goes thru a Raycor filter and water trap assy with electric indication on the dash for was collected, The fuel is filtered at 6 micron. This unit has a plastic bowl, however I have it mounted high up above diff level, and in a metal box for protection. Prior to this I ran a CAV filter with toughened glass bowl without issue, but it was inside the metal box. I changed from the CAV to the Raycor because the fuel rate capacity thru the CASV was too low for the s/c application. The location is a PIA but for the frequency of swap out for me, I would not do 2000klm/yr I reckon, its fine. The filter is before an Aeroflow BLACK series booster pump. This flows at 530lpHR which is plenty for even the chev which runs at WOT of circa 70LPHR. This maintains a constant 13pSI boost pressure to the IP at idle and 11PSI at WOT. I found when I first installed this pump as an upgrade to the original fitted by Brunswick Diesel, when the vehicle was N/A configured, the engine immediately ran better, totally different feel to it. The pump then pushes thru a cartridge spin on unit with the hand primer of 2 micron into the pump. You can see from the numbers there is a significant amount of fuel avail and also returning to the tank. There is a strong regard for Carter pumps I believe. I found the value of the Aeroflow best for me because I like to carry a spare and from a cost perspective it was easier on the pocket whilst getting the performance. Regards filtration, 2 micron is pretty conservative for this old technology pump, but it suits my mindset - i have heard 5-6 micron is probably just as reasonable.

I run calibrated flowmeters on the supply and return lines plus a calibrated fuel pressure transmitter and a standalone fuel management computer, so these numbers are accurate. For cold weather I have 120w thermal blankets on the pump , the filter bowls and also one on both tank bodies. i have just ordered an in-line heater unit as well, so this will eliminate any waxing/gelling in cold weather such as weekend snow trips where I camp in the snow and it gets well into the minus temps.

Hope this helps.
