This unit was pulled from my 84 Vanagon with Tiico engine conversion
after approximately 16,000 miles of use. Unit was replaced with an A2
fuel rail, injectors, FPR, setup. FPR was in perfect working condition
when removed.  If you have a Tiico and do not have the A2 setup or a new
fuel pressure regulator, I would seriously look at this.  Made a big
difference on my van's performance after the engine conversion.

Thanks,
Derek
