Regina Pump Assembly part question
 

I just posted a reply to an old thread, but wanted to ask my question here as well.
The thread is here: https://volvoforums.com/forum/volvo-...63/#post475339

My question, repeated here, is whether or not the "accumulator" (or pulse modulator/dampener) referred to here: https://www.volvoclub.org.uk/faq/Fue...eplacement.htm is a necessary component of this delivery system since, as I describe elsewhere, it seems like a weak link and I seriously doubt capable of sealing at the pressure this system is rated at.
