where to hang my holley blue electric pump?

i need advice / recommendations.
i had a fuel boilling issue that gave me a reason to spend more money on my dart. i have run a 1/2" line away from the exhaust to rear of car. i have a comp. engineering sump on the rear of fuel tank. where should i hang the pump? it recommends upright vertical / closest to tank as possible and lower than the sump fitting ( which likely isn't happening with lack of space. anyone mounted one on a 67-76 a body with success?
