re: tank conversion

Ray, you should take your address out of the location. It more of a general question and displays on the right hand edge of the screen.

Anyways, there are a couple different options for what you need to do.
You can get a weld in sump to modify your current tank to work, check summit racing.
Or you can get a whole new tank from numerous sources.

re: tank conversion

even if you run an external tank you need to baffle your pickup in the tank. There are several vendors that offer a bolt-in baffled tank with intank pump and return line that will fill your needs nicely and protect you from fuel starvation, for under 500 bucks.

re: tank conversion

Tanks Inc. has an in tank pump. You will need to cut a hole in your tank.

re: tank conversion

All you really need is a piece of 3/8" hard line and some JB-Weld. Use a piece of coat hanger and bend it like your existing sending unit line to where it connects to the hard line on the frame rail. Use that to bend the 3/8" hard line to shape with a couple of inches on the end to stick down in the sending unit plate.

Cut off your existing sending unit line leaving the portion that extends to the back edge of the tank. Drill a hole in the sending unit and JB-Weld in the 3/8" line you bent. Connect that to the hard line on your frame rail and it will now be your return line.

Use a double flare tool and only the first step of a double flare to make a bulge or barb on the end of each line where you are going to connect fuel hose.

Connect to the cut off end of your original sending unit line and run to your pump which should be mounted close to the tank and as low as practical. Run flex line from the pump to the regulator and throttle body. The Summit Racing braided flex is 100% synthetic nitrile lined and rated for 1000psi.

Conversely, I guess you could cut the sending unit line like above and cut the hard line off before it travels up the frame rail and use the hard line as your feed line but you would need the correct high pressure fittings. Then you could mount the regulator on the frame and run the return directly back to the tank while having just the feed going to the engine compartment.

I do not have the starvation issues some have reported while using the aftermarket tanks.

re: tank conversion

summit racing also has sending units allready with a return line on it aswell. i just got mine.drop the tank swap it out.
run regular fuel line or hose to the pump as low as you can as steiner said. add high pressue line from the output side of the pump. i used the factory line as the return and braided with -6an fittings for output.

im in the middle of doing this all now and it seams to be working sofar ill keep you guys up to date if any probs and open to sugestions.

re: tank conversion

Don't listen to Steiner! He's a perfectionist.
Do it like this,,,,sorta. The return line is now the original feed line at the top of the tank because the regulator is now on the engine. Oops, didn't Steiner do it that way?

re: tank conversion

I just installed an EzEfi on a 68 Camaro. Didn't do any mods to the tank and it's working ok so far. I haven't autocrossed the car but in simple driving around I got to 1/8th tank and it didn't stall or anything. I'm not saying a sump isn't a good idea, but I think the throttle body type system is a little more forgiving than some of the others.

I attached a plate to the fuel tank straps and mounted the pump to that, used the stock pickup as feed to the pump and drilled a hole in the front center of the tank and installed a bulkhead fitting for the return, dash 6 AN.

re: tank conversion

I'd planed to use screws to hold the plate seen in post #8 to the tank straps. Then I lined up the plate. Wow. All I had to do was make a slight cut in the sheet metal at the bottom of the retaining straps so the sheet metal would follow the curve of the tank. Then loosen the straps, tuck the mount under them and tighten. Two bolts at the top are the only fasteners needed. The center flange of the gas tank holds the plate away so that the pump vibration mount studs never touch the tank. Here's look again so you don't have to scroll.
