I've got a Holley hp 125 pump and 3/8 lines all the way. I'm Just wondering is it enough for my new 496 with a 950 cfm?? Approx 700 hp.

125 PUMP WITH A 1/2" LINE IS GOOD FOR ABOUT 550 hp, MID. 11 SECOND B BODY. i WOULD BE MOUNTING A SECOND PUMP AND LINE TO THE 950 TO SUPPORT 700 HORSEPOWER IN A 10 SECOND RIDE..


Cool

Problem is they don't make a factory style sendor unit with a 1/2" pickup. And I'm not welding anything to my tank!

this part # from spectra premium has a 3/8 tube.. but it also has a return tube installed..

Part Number: FG93A
Notes: 3/8" outletIncludes fuel sender, float and strainer


you might be able to pick up one of these... and remove the return tube.. enlarge the hole and perhaps use come kind of either bulkhead connector... or a creative use of a compression fitting with a tube straight thru it after drilling out the stop in the center..

use copper sealing washers.. and a double compression fitting..  or some of the high strength low melting point silver solder found at some hardware stores.. i have a specific part number if you would like ..  alpha metals #53982

there is also a higher percentage of silver solder available.. but it requires a LOT more heat to melt..

test fit and install tubing and a nut TIGHT on the short side...   you will want a strainer on the end..  or be sure to cut < shape to the end to prevent clogs from objects..

place a sealing washer over the long end..  either copper.. aluminum.. or perhaps one of the rubber lined oil pan drain washers if they make them that big...

insert new pickup and this bulkhead fitting thru the sending unit opening  then back thru the hole you made in the side of the tank...  place another sealing washer on the long end that is not sticking thru the tank.. the jam nut and while looking into the tank.. position / rotate.. the bulk head fitting to get the pickup end the proper distance from the floor of the tank...

you can now tighten the outer jam nut.. using a wrench thru the sending unit opening..

you now have a 1/2" pickup..

you may also want to even think about how much fuel you race with..    if you are drag racing or  circle track racing.. you will have to account for the G forces on the fuel during acceleration or banking..  so you don't run the pickup dry..

i wonder.. if at 1 G acceleration if the surface level of the fuel is at 45 degrees???  i don't know as i don't know this kind of physics.
