Ive read that they have different part numbers from obd1 to obd2, but someone said its just the crank sensor mounting position is different???

I am using my obd1 head and electronics, with an obd0 B18a block.... Which do I need? I would really like to reuse my B16 pump if possible cause Im strapped for cash.

 

its doable but dont do it. obd2 pumps have a higher flow rate. Spend the money and get a new one
