Walbro fuel pump pulsing?
Im almost done my turbo-vert conversion, and was testing the fuel system when I noticed that the fuel pressure now pulsates. I have one of the cheap fpr from ebay on the return line. The stock pulsation dampner is still in place, however the secondary rail has had the stock fpr taken off as it should. Is this normal?

Does'nt sound normal to me.....
Is it an ebay walbro fuel pump?
The ebay pumps are knock off's that look EXACTLY like the real one's.
That ebay FPR might be causing the fuel pressure to pulsate.....
Or maybe the missing fuel pressure regulator may be the problem as well.
The fuel pressure regulator is there to regulate the fuel pressure just as it's name sounds....
Try getting a known good aftermarket FPR and try that out.
Wait and see what the more educated guys say though before buying another FPR.
It may be something simple that I may not know.
