Dual FPRs

[Xero_Tolerance]

Ok, I don't know if this has been answered. I tried searching but couldn't find any threads on this...

I have a walbro 255 so I needed to get an fpr. So I get one but it doesn't have an adapter to fit right into the line so I thought about it and if I put it after the stock fpr then it should work just as well. Because the problem with the stock one is it gets overflowed so having the one after it would regulate the total pressure to whatever it's supposed to be, 37psi in my case and then the stock one wouldn't really be doing anything. That's just what I thought but maybe I'm wrong so if there's something not right about that then please let me know, I don't want to mess up my car. Thanks in advance.

No because you need to lower your pressure and make it more stable, you need to get rid of that stock regulator totally.


I tapped the rail 3/8th NPT and used a 3/8ths NPT male female fitting. Then a 90 deg 1/8th npt elbow to a 1/8th NPT Barbed fitting. I painted it all black afterwards, then ran regular high pressure fuel line to the regulator and gauge. Cheap and super effective.

Wow, look my old 2G motor. She took a beating...

Yeah I'll go buy an adapter and tap today so I can get workin right. But I was thinking, couldn't I just strip my current fpr so it would just act as an adapter?
