Swirlpot Fuel Pumps

Another fuel , swirl-pot thread...  its time for me to build one...

 

So I have a couple of thoughts, first is what about internal vs external pumps...  can I just take the current in tank pump and move it into my swirl pot?  any reason to use internal vs external?

 

Then for my fuel tank side...  do I just buy another fuel pump like the one I have in my tank, stick it in the swirl pot and call it done?  or do I need a "low pressure" pump?  Do I need to size it differently so I dont pump so much excess fuel around in my car; since I need to move like 10 gallons per hour to the swirl pot, certainly not 380 LPM or whatever...  and not at 40 psi...

 

I also am aware that some teams attach a AN fitting to their stock tank, and that this may or may not be legal as it modifies the stock tank...  I dont necessarily want to debate that, I will leave it to tech to make that call, but if so, I assume its to use a self priming external low volume pump.

 

I heard something about an old F150 pump being the ticket, available at any autozone cheap and external, easy to plump, anyone know about such things?

 

Ideally I would like to avoid the 140$ small Hydramat on the OE pump / Sump in tank, and another 100$ in tank Ethenol Safe fuel pump...  I also would worry about the AMP draw, since that primary pump pulls almost 20 amps as it is.

 

 

As for location...  in this particular car, we will either...  put it on the passenger side and set it up to fill the tank through it...  IE able to fill the tank from the passenger side without messing with the OE filler neck by filling the sump...    OR...   in the passenger dash / Cowl area, where the OE FAN was located...   OR in the engine compartment where the OE battery Tray was (least favorite)...

We raced the last few year on the stock Mustang fuel pump which is 88 lph (litres per hour) and it did fine for us.  Our lift pump is a low pressure Facet 40106.  Internal pumps are pretty bullet proof as they have the fuel to keep them cool, heat kills electronics.

You may want to move fuel a little faster, let the return lines return

Your stock in tank pump is fine.  Don't mess with it.  It will not be regulated, so the pressure will be minimal.

 

Get an external pump, like the above mentioned f150 pump to feed the engine.

FYI, we're running a volvo penta unit. It's literally an all in one thing. Has a low pressure lift pump into a small (couple quart) reserve, a filter, and a high pressure pump for the FI.

If you hunt ebay usually you can find them for <$300.

Looks sexy but I dont think its ethanol friendly... any feedback on how it handles it, for our supercharged motor I like to run it on E85 or E85 blends to keep the intake temps down..

 

Something about Volvo painting the inside of the filter area to help seal the cast aluminum...   the ethanol strips the paint and sends it through the pump making it whine and clogging injectors...

E 85 chumper.. 

 

Yep, for this car, no one needs fear, on E85 we are lucky to hit 1 hour on the stock tank on a big track...  hence the need for the swirlpot as the next upgrade.

 

We have another car with getting a swap motor without the supercharger, but our gas around here is still all E10...   so getting something that requires ethanol free gas will just increase our costs.
