DIY regulated return question

Anyone know if I can tie the return line from the regulator to the test port on the factory fuel bowl return side?

Just remove/gut the factory regulator, run the return line from the factory spot in the bowl, straight to the regulator, to the return line to the tank.

Re: DIY regulated return question

Thanks for the response Airsley but I dont follow. Im wondering if I can connect the return port on a aeromotive regulator to the plugged port on the fuel bowl. I wanted to leave the factory regulator in place if possible. Referring to the plug next to the factory regulator on the fuel bowl.

Thanks

Re: DIY regulated return question

Why leave the factory regulator? It sounds to me like you are not understanding a regulated return. Break it down tank, pump, filter, injectors regulator tank. It sounds like you are asking about putting the regulator before the injectors.

Fuel comes from the pump to the bowl. From the bowl to both heads. From the bowl, through the regulator, back to the tank. Are you planning on adding a second return line?

Personally, I am going to change mine a bit. From the bowl to the back of both heads. From the front of both heads to the regulator, from the regulator into the factory return line and back to the tank. I will plug the factory regulator on the fuel bowl. I also plan on running it through a pre pump filter, and through a pair of Super Duty pumps set up in parallel.

I think I get the concept. In fact I am only doing a rr not a complete fuel system so we can forget about the tank, pump, after market filters and such.

I am also not talking about regulating the supply as you have stated. I understand that would not make sense. I am building a rr using an aeromotive reg and crimped hose. I will feed the heads from the supply side of the filter bowl and return the fuel path into the aeromotive reg from the opposite end of the heads. The question is instead of having to build a tee fitting to connect my aftermarket reg to the factory fuel return line, can I connect it to the plugged port on the return side of the filter bowl and leave the factory regulator in place? Unless I am missing something that method would still give me a flow through design and regulate the pressure in the heads.

Am I off base here?

Re: DIY regulated return question

I am trying to visulize.
It seems you are looking at it diferently than me.
If it were me doing this. I would gut the factory regulator cut the return line from the bowl install the regulator inline and be done. I am not understanding What T you speak of.

I am trying to keep the factory lines intact so that it can be returned to stock later if need be.

Just wondering if there would be a problem with connecting my return off the aftermarket reg to the plugged port on the return side of the bowl to avoid havin to cut the factory return line and clamp on my after market return hose.

I am trying to make sense here but I think i might be speaking dorkfish. Anyone know what I am trying to say?

Re: DIY regulated return question

Ok I think i see. I dont see why not you just have to figure out how to seal off the factory return.

Re: DIY regulated return question

Just get a regulator block of plate, cut the end of the return line off, and tap your regulator outlet into the factory return.
