Would you rather spend $50-$75 more for a regulator, or replace $125 in-tank pumps every few months?
That Holley regulator is the wrong thing for this application. The in-tank pump requires a constant flow of fuel to keep it cool.
Get a return-style regulator like a Mallory 4309 (more expensive) or Jegs 555-15909 (less expensive but adequate). That means you'll be using the return line again. That should stop the leak.

the other option is to drop the fuel tank, remove the intank electric pump, replace it with a carb style pick up, and run a block mounted manual pump.

i was also told when i take the intank pump out i have to modify the sending unit somehow. Last edited by 86mailman; 03-25-2013 at 08:54 PM.

i was also told when i take the intank pump out i have to modify the sending unit somehow.you still need to drop the tank and remove the intank pump to run the external holly pump. and you still have to use the return style regulator unless the pump has a built in regulator. to keep from burning the pump up.
