Options to upgrade or bypass the fuel pressure regulator

Just realized during my fuel pump upgrade that there is a fuel pressure regulator at the outlet of the fuel pump assembly inside the tank. It is 39 PSI and my RC51 engine is designed for 50 PSI.

The regulator appears to be Bosch part 0 280 160 690. I think the easy solution would be the same regulator just at a higher pressure than 50 PSI but I cannot even locate the stock part neverless a high pressure one on the internet that would just "snap in" ... of coarse not that would be too easy . Anyone found a higher pressure one?

Or I should just be able to bypass it all together correct since I still have my 50 PSI regulator on the RC51 engine. Or am I overlooking something? I already did the proper return line from the RC51 just need to get something greater than 50 PSI over to the RC51 regulator and I think my new Airtek pump is like 100 PSI output.

What options are already out there for some adaptor that just allows you to bypass the regulator within the stock fuel pump assembly that goes back in the tank? Its just plumbing but want to make sure it doesnt leak etc. and assume some of the big bore or turbo guys have done this. I just need the regulator bypass not a full pump, external regulator, etc. kit.

Re: Options to upgrade or bypass the fuel pressure regulator

I've gone to a fuel cell, but the way the Weber kit is suppose to be installed they use a bolt (tach welded in place) to hold that stock Polaris fuel pressure regulator wide open (full pump pressure) - If your pump puts outs 50 lbs and your RC51 pressure regulator is still in place, block the in-tank regulator open and you should be good to go...The picture is not great, but you can see the bolt in the regulator

Re: Options to upgrade or bypass the fuel pressure regulator

Cool, any more details on exactly how to do that bolt? How do I know it is a done deal as not familiar with exactly what the bolt is doing but assume its got something to do with the spring?

Re: Options to upgrade or bypass the fuel pressure regulator

I wish I could help in that department, but, I sent that unit to the "Joker" he was having some running condition issues, you could PM Dan aka the "Joker" and maybe he would look at it in person & be able to tell us how that bolt is in there...

Re: Options to upgrade or bypass the fuel pressure regulator

On some GM TBI throttle body assemblies you could use a socket and put it over the
diaphragm area and hit it with a hammer to adjust for higher pressure.
Most likely the same idea as the bolt thing.

Re: Options to upgrade or bypass the fuel pressure regulator

Found out K&T Performance includes a custom machined aluminum regulator block off in their turbo kit and they hooked me up with one. You just pull out the metal clip that holds the metal regulator into the plastic housing, regulator has a couple orings that are fairly tight inside so have to tug and twist it out with pliers, re-use the OEM orings on their block off piece, put the clip back in, and the bypass is done. Could tell instantly my engine likes the higher pressure ...
