Re: Corvette Regulator with a stock 5.3 return line Fuel rail
all, I will get a pic tonight & try to post . I appreciate the responses & I am only wanting the thread to be helpful (to me ofcourse) but also to others who don't have knowledge (as myself) of how to handle a similar situation. As in many problems there can be multiple solutions & opinions. ;) Obviously the safety aspect is highest priority and hopefully that solution isn't too expensive.:ito:
thank you guys for the information and support :metal: |
Re: Corvette Regulator with a stock 5.3 return line Fuel rail
First off, Mongo, you're right, I'm not a fan of blocking off the return, but glad there's no hard feelings about it. This is why I said I refrain from mentioning it. That said, in recent times there have been parts made to make it safer. One of my pet peeves about it is the known fact that when the regulators fail, they leak past the diaphragm, which without a vacuum hose sucking it back into the intake, will allow gas to just run all over the intake. At a bare minimum, I would get rid of that for peace of mind. ICT Billet now makes a block off for it, and for $20 and about a half hour of time, would be well worth the insurance. https://www.amazon.com/ICT-Billet-Re.../dp/B084KN6CHH

Re: Corvette Regulator with a stock 5.3 return line Fuel rail
Thanks Eric...I didnt know about the ICT piece either...I'll def look into it..
And man naw...no hard feelings at all...I see you helping a lot of folks with all kinds of issues... gotta respect that you take time to do so.. |

3 Attachment(s)
ok guys... here are the pics. one is it attached using the factory "quick connect" fitting - and the "plastic" line molded on. another pic is with the assy. disconnected & sitting on floor. lastly a pic of the end that has the hose fitting and cap. please feel free to voice thoughts. I want to reiterate that this setup is for a 2013 4.8 truck engine with 57K miles. I guess I don't know what the solution is to handle the return line at the engine?
ls1nova - i looked at the link, but confused on "how" it works and purpose? in some of the reviews it was indicated that this was not a block off plate? also it is recommended for up to 2003 engines? finally as I indicated previously, that when I tried to use a "aftermarket" (fragola) fitting the "clamping"? portion of the fitting was too long and would not fit on the engine return line - hence the re-use of the factory line. I REALLY appreciate the responses from you guys & I apologize for my lack of terms & knowledge. you both (the board in general) are very patient :metal: THANK YOU:metal: |
Re: Corvette Regulator with a stock 5.3 return line Fuel rail
I forgot to mention that the end of the line points down to the ground just incase a leak occurs. obviously i want to do the "correct -safe" solution...;)

Re: Corvette Regulator with a stock 5.3 return line Fuel rail
I'm not sure about that....it "might" be ok...and it might not...
as for it pointing at the ground , think about where the exhaust is, and fuel spraying around ....if it should fail If you have the correct pushlock, it will snap right onto the rail...did you have the correct size?... I havnt looked at Eric's link yet so I'm not sure what involved there.. You can always change the fuel rail to a returnless rail...junk yards are full of them... |

Re: Corvette Regulator with a stock 5.3 return line Fuel rail
Mongo, yea I see your point... I was thinking along the lines of the fuel leaking onto the engine. I am not really wanting to change the rail, although if that is the common sense/practical solution then I can attempt that.
"So your engine is a 2013? If that's the case, you don't have a return, so you also don't have the regulator on the rail. Hard to tell from your pics, but it looks like you have a metal fuel rail yes I do), so, I think what you are seeing is the purge solenoid line. I know for a fact that the purge solenoid line is what you capped off, and it is in NO WAY capable of holding fuel pressure, but it appears you don't need it anyway." nova, I guess I am still not understanding? I apologize.... so what should I do (your recommendation) with the line :confused:? originally it ran next to the fuel feed down to the frame side and then not sure. when I got the engine both lines were cut right after they turned into the braided line material - next to the transmission. I assumed that it was a return line... but???? again I thank you guys for your patience with me.:metal: |
Re: Corvette Regulator with a stock 5.3 return line Fuel rail
Ahhhh...2013....
What Eric's saying is if you have a 2013, there is no return rail...probably why you couldn't get the quiklock to work |
Re: Corvette Regulator with a stock 5.3 return line Fuel rail
ok guys I did a little investigating now that I know what that is. so!.. if I understand right then could that line be connected to the '86 charcoal vapor canister? if not then just put a vacum cap over the line/engine outlet? ... am I understanding right? :ito:
thanks again!! |

Re: Corvette Regulator with a stock 5.3 return line Fuel rail
"..... but without the wiring going to it, it would never open"
what wiring are you referring to? my engine is a complete drop out & included all wiring. the valve is OG to the engine & is stock. sorry for not understanding...:waah: |
Re: Corvette Regulator with a stock 5.3 return line Fuel rail
I figured you had an aftermarket harness or had modified the factory one and it was removed because it isn't needed for the engine to run. The wiring for it will be in the factory harness, but without the fuel tank pressure sensor I'm not sure it will ever get the signal from the PCM to open. The PCM runs a diagnostic on it at certain times to make sure there are no leaks in the EVAP system, and it's what controls the purge solenoid. Some people say it will work without the tank sensor, but I've never tried it.

Re: Corvette Regulator with a stock 5.3 return line Fuel rail
nova, thank you, 10-4 on the info. i will just cap off the line and keep it hidden under the factory engine cover.
in general, all I really appreciate the replies & information. hopefully this will help someone else down the road as well. |
