    EFI Tank Options
    « on: September 08, 2009 - 04:07:23 PM »
    I'm planning to switch my car over to EFI within the next two years.  I'd prefer an in-tank pump, but not if it adds major $$$ to the cost.

    What are my options for tanks/pumps/etc?  What are the 5.7 and 6.1 HEMI guys running?

    I did my own for about $350.00 plus the new tank.

    I dint want to spend the $800 to $1200 for the stuff on the market.

    I'm using a low volume pump from the sending unit, thats plumbed to a fuel sump with a hi-pressure pump in it.  The hi-pres pump goes to the regulator/filter with a built in return.   The return goes to the sump, and then overflows back into the tank at the sending unit. 

    The sump I used is a 10" water filter housing from Home Depot, about $20.  I thought of using a marine fuel filter setup, but you can't submerge the hi-pres pump with that, and I wanted to save money with a inexpensive factory replacement type pump. 

    It all bolts to the brace in front of the tank, with the sump housing at a slight angle to tuck it up some.   I've got my new fuel line and the low pressure pump installed, and have the sump housing.  I just need to get the 90's mustang hi-pres pump ~$90 and install it and wire it. 

    I'm going to run it on a 07 hemi.
    I have a question.   Has anyone found a nice junkyard relay/fuse box for under the hood?  The one in my ranger pickup would work nice.   3 relays and lots of fuses in a 3x6" black case.   I'll need relays on my fan, headlights and fuel pump.

    Do you see any reason to run separate relays for each pump?

    Here are some pics of what I'm talking about.

    Here is another option for a fuel sump, its a marine fuel filter, kills two birds with one stone, but you need a hi pres fuel pump that can survive not being submerged. 

    fuel separator

    and finally, the 99 corvette fuel filter/regulator/return line.  So mount this by the pump and only one line needs to be run to the front.  Then you can just use short lengths of inexpensive FI hose. 

    99 vette fuel filter hookup

    I have all the parts for this now, except the pump itself.  I was trying to find a hi pres pump under $100 but it seems impossible.  Please let me know if you may know of a cheap pump for this setup.

    Thanks and good luck,
    Chris
