Fuel system build

[smokinstroker]

wait to until you have the extra $50 to buy a sump to complete your build, do it once and right.

i opted for this option rather than having to worry about 2 pumps and wasting extra money on that.

10an bulkhead with 3/4 line not enough?

-10 an fittings and hose will be your friend here

So -10an hose from a sump to the hp pump should be good? I would really rather just use one pump than have an AD feeding the hp pump. That seems a bit overkill

when you say bulkhead, im assuming you mean out of a draw straw from the top of the tank?

the idea here, like described in the beginning of the thread, is that the pump have to do minimal work to get fuel to it (supply from tank to pump)

gravity is your friend in this situation.

a drawstraw being at the top of the tank will require the pump to pull(syphon) from the tank (up and out) which is where the "pusher pump" comes into play. keeping the HP pump happy and primed.

with a sump you have the supply line coming from the very bottom point of the tank. Obviously your pump is not going to be mounted lower than the bottom of the tank, so you will have some upward slope, but the pump/filter will be roughly even or lower than the top/middle of the tank.

this helps keep the supply (feed) line full and helps the pump prime easier.

the ideal fuel setup runs as follows
tank>feed line>water separator>pump>filter>regulated return>back to tank

the pusher pump will in no way hurt the system, it is actually a good idea if you want to fork out the $, just make sure your LP pump does not restrict flow on the HP pump.

hope this helps.

Bottom of the tank.... Sump will take its place

you should be good to go buddy. just an opinion here, but a ball valve helps out great here.

Laying on the floor waiting on the filter base as we speak

Helps for sure. Was planning on using a sump the whole time...

you don't need a pusher pump if you use the suction tube....it's a matter of preference. Just using a HP pump and a larger suction tube works fine.....many are doing it and i even installed a handful with zero issues to date. I've installed different setups...all having no issues. I've installed a HP FASS pump system still using the factory suction tube and that truck runs great. I've also installed a sump to a HP pump and i also installed a sump to a FASS low pressure pump system to a fuelab/A1000. All work great...you do not ever need a sump with a fuel system....it's just a matter of preference for some. Only reason i installed a hellmann's sump is because my larger 5/8" suction tube was sucking air around 1/4 tank....with a sump, it no longer starts to suck air until just under 1/8th tank when it sloshes making turns or going up/down hills.

So if you have a 10 micron filter and a 2 micron filter, which order does it go in? I confuse the water separator with the other. I have instilled in my head the order sequence is 10 micron then 2 micron (post pump).

 

[FX4 F2-Fifty]

ideally: Sump >> 10mic fuel/water sep >> Pump >> 2mic filter >> heads.

Thanks, got it :thumbsup: My brother has everything we need here to install his setup, but the fitting on the sump is only 1/2", if a 5/8" hose is used for pickup it will do no good, no? He wants to scoot by with a 1/2" line to the pump, but what option does he have other than getting a different sump?

 

[strokin6L]

i don't understand why you would want two filters. Just run the smaller micron filter and be done with it...it'll filter both the small and large particles at once. I'm only running one 3 micron filter....that's it. If you run more that one....start with the larger one first then the smaller. That's how the stock system is. The one at the bowl on the factory setup is 4 micron i believe.

you use a 1/2->5/8 fitting...that's what i used on my hellmann's sump.

 

[09stroker]

IMO 10 micron pre pump might restrict it if it's a large pump.
I would want something to filter any large particles before the pump plus you'll get alot longer service life out of the filters.

 

[01PSD]

I just figured it would alleviate one filter from having to do the job of 2 filters. That way one is purely a water separator and the other is for debris, etc.

 

[01PSD]

Maybe I'm just not getting it, but if the fitting is only 1/2" in diameter, that's all you can flow throughout that line, correct?

 

[strokin6L]

nope....not if the line is bigger than 1/2". The fitting is 1/2"->5/8"...My fuel line from my sump to my low pressure FASS pump system is 5/8"(-10)

 

[09stroker]

1/2"Npt is comparable in size to 5/8 AN aka -10.
1/2" in Npt is the inside diameter whereas AN is the OD of the tubing, so you have to take out the wall thickness of the tubing compare it to Npt.

Ok thanks guys, just trying to get on the same page!
