I think I have an easier solution I work for Jeep and if you are converting
a Wrangler why not use a 1991 and up fuel tank and pump? In 1991 we changed
from carb. To fuel injection and the 1991 to 1995 Wrangler fuel tank should
fit NO PROBLEM in the 1987 to 1990 chassis, I think you can still get
factory feed and return lines but I would step up to 3/8" for the feed and
use the factory 5/16" for the return just incase you need MORE POWER!
