The only solution worth considering is to rebuild your existing fuel pump.
ALL of the new ones available today are sub-standarded garbage made in China. They fail almost immediately or fail to perform straight out of the box.
Contact Then and Now Automotive to get a kit to do it yourself, or send it to them to do it for you. They rebuilt mine several years and 10,000 miles ago after 2 new ones failed.
The one with the gold cap died after 300 miles. The silver cap one didn't pump a drop of fuel after installation.
This is a problem that almost every person on this site has experienced.
