Sr20 fuel pressure issue

[wmblnknshp]

My sr is losing fuel pressure at wot. I have the fpr set at 43psi with out vac. At wot it drops to 10. I have a new inline Walbro 255 on a switch. Not sure what else to check. Any ideas?

Fuel filters?

Leak or power issue!
Power, pump on then read pressure. Turn power off.
Wait 2min is there still pressure? Probably not. If there is check voltage at pump during your wot pull.
If all good change your filter.

The pressure bleeds off in about 5 mins. I don’t see any leaks. Does that mean it’s the fpr?

Possible causes are fuel injectors, fpr or pump. Pick the least expensive, easiest and try to narrow it down
