Same would go for ECM failures.

The ECMs are much easier to get at which may contribute to their availability also.

The Fuel Pressure Regulators are rare also and as corroded as the tops are internally in some cases I expect to see more Fuel Pressure Regulator Failures (Who is to say this does not contribute to Injector Failures way too early).

I have 4 or 5 extra Fuel Pressure Regulators having five originals converted by Phil which replacement cores are now easy to obtain on Ebay for $30 or less and easy to install (5 minutes). My injectors may now last forever

Also have 3 or 4 extra ECMs and a couple extra DIS which if we keep everyone thinking they are like gold
