What happens when your existing pump hits that 5 PSI? Does it stall out, or does it keep on running? If it stalls out then look elsewhere for your trouble, if it keeps running, then there is a relief valve that might be causing your trouble. What kind of flow are you getting @ the injector pump? Not just at the filter, down the line to the IP itself. Are you still running the steel line with the rubber ferrules, or did it get changed to a hose? If it is a hose, it could be peeling on the inside and causing a serious restriction.
The link I spoke of earlier is amazon.com search electric fuel pump. They have a whole lot of choices. A fuel pump that would work on an old carburator is all you need. They used to use them all of the time when they changed their engine over to run the Holley double pump carb. for racing (flooding) purposes. Overkill sometimes hurts, as bad as under-kill
