Aite Gang, I'am gonna try an keep it cool. With every one here,
but seriously. A lot of people can't just add there 2 (negative cents)
with out me even explaining myself..... If I had a chance to talk to you one on one, on the phone i can explain .....
I'am not too good in explainin in writing...... .

I'am going to explain what I have, in the best way possible, (If there are question or concerns, ask and Ill try to answer on the best of my abilities.

1st.
I do still have my stock fuel pump, ( I Have a walbro, at the house, but i've never tried to put it in because i tought stock one would work just as fine *for 7-8psi's*)

2nd.
As you guyz probably saw in the past pictures, that external Fuel Pressure regulator, set at like 45 psi's.

3rd
RC 310's Fuel Injectors
4th.
Custom Fuel Rail.


As you guyz saw the previous FPR pick, *the left side hose, is going to the Fuel Rail. From the other side of the Fuel Rail,*that hose* go's to the bottom of the FPR. This is the part that if i had a Return line, I would split them in half with a T line, so one hose could go at the bottom of the FPR and the other hose would go to the tank. I'am not too sure about this one, But you guyz knw that little tube type thing thats on top of the stock fuel rail...? the one that has vented fumes or something, well I think we have that one running on the Right side of the FPR.
on top of the fuel pressure regulator, you may c a lil Vacuum sort of inlet where we have a PSI hose going in there, that way it read's boost and the pressure go's up as you spool up.

*( I know a lot of you may say this is bad, It may be. I dont knw. Like I've sayd before, I've worked on many cars *specially GSR's and V8's*but when i got to this car, it's been the most trickiest yet.* (lol) I knw you guyz probably agree with me as well.*

(ok, out of that sayd, )

1.Can some one here explain, why my car is running good right now?

2.If I had to add a lil extra something, to have it runnin the way it's SAFE to run, what do I have to add.? An extra hose for the Return line and Walbro?

3.After, I do this, I'am most likeley going to have to have it tuned again?

4. If you think this is fine! Explain why you think its fine! Is it because you believe what i believe, and its working because it kinda acts like a Return Line?

5. What if I swap my Stock pump, and put the WALBRO 255lph?. Will the External FPR work fine with it. Would i be fine running it with out any Return line?

Mabey if you drew some sort of diagram it would help them understand a little better.

Just because your car isn't having any problems, doesn't mean that setup is working. You could run as much boost as you are running without a return conversion (ie stock fuel pressure). I don't see a picture that shows your gauge reading 45 psi. I see pictures with a gauge reading about 36 psi. (which I think is the stock fuel pressure). I work on a large water distribution system in California and we sometimes rig up temporary pumping systems that mimic return fuel systems. From my knowledge of pressurized systems, it doesn't seem like your setup would increase pressure at all. There is a possibility that I am wrong and that your system works but I see no evidence of that.


Also, The only benefit I see from using a setup like this as opposed to a full return conversion is saving a little money on hose and a fitting at the fuel tank. But, with the fact that this setup is still unproven, I feel that the "pro's" don't out-weigh the "con's".

If I were you, I would buy a little bit more hose and a fitting at the tank to just go ahead and do it right.

Oh, my bad.. The reason its reading 36 psi's is because I turned my car off!.....Would you want me to take a pic of it while its 45psi's *when car is on*?

i think i see how your setup works. fuel goes from the pump to the fpr to the fuel rail and back to the fpr where it is restricted which increases the fuel pressure. the difference between your setup and a basic return-fuel setup is that the fpr is situated on the other side of the fuel rail, restricts the fuel, then sends it back to the tank. so basically your setup is just a ghetto rigged return-fuel system.

1.Can some one here explain, why my car is running good right now?
Running right? It may or may not be. Just because it appears to run properly dont mean that it is

2.If I had to add a lil extra something, to have it runnin the way it's SAFE to run, what do I have to add.? An extra hose for the Return line and Walbro?
Here is whats needed to do it properly

3.After, I do this, I'am most likeley going to have to have it tuned again?
Well the fuel supply may have some effects on tune, depending on what Fuel management you are running. So i would say yes

4. If you think this is fine! Explain why you think its fine! Is it because you believe what i believe, and its working because it kinda acts like a Return Line?
I dont think its an improvement at all over stock. Your not increasing the pressure or flow capability

5. What if I swap my Stock pump, and put the WALBRO 255lph?. Will the External FPR work fine with it. Would i be fine running it with out any Return line?
I still dont follow the total concept of returning it to the fuel line AFTER the fuel pump? This is the way i think SF does it on thier Fuel system, i think. And i guess the bleed off pressure that is going back supposedly to the fuel line after the fuel pump would be low pressure low volume so i dont see it actually being able to return back into the fuel line with efficency(sp) And to take advantage of the external FPR and walbro you will need to remove the in tank FPR. Being that you have a FPR already and the walbro i dont see why you wouldnt set it up correctly with a seperate return line to the tank

 
Rep Power: 327

Not in the pump itself but its in the tank on the out put side of the fuel pump

 
Rep Power: 607

yup

thats too bad, im looking for a non-vtec for a motor to build!

hmm, so we have a stock fuel pump in our gas tank right? So what happens if it fails, couldent we put an external fuel pump/fpr outsiude it since the other one isnt wokring anymore?

buy it, build the block, sell the head then swap ur head onto the built block, tada

Thats an awsome answer..... Thnx bro!.
anyhow.. Its that ( what i need to do)
Is that just talking about how to take the Stock Fuel Pump Out?

 
Rep Power: 0

What I'am gonna try 1st is, taking out the stock pump, C if i can find that stock FPR, Remove it completley and slap in there the Walbro 255lph...... I am gonna c if it works that way... If not, I guess i am going to have to go to Discount or something, *buy an extra hose* and a T line that i can cross the fuel to FPR and to the Tank.

Sounds straight?

 
Rep Power: 607

it wont' work cuz the fuel running back to the fpr is gonna flood your line. You already have the pump, fpr and your rail is modified. Just spend the couple extra bucks and a few hrs and install a return line..........the correct way

 
Rep Power: 327

When i get one, i was wanting to do a MILD port job, mainly gasket matching of the head

 
Rep Power: 0

So all i need to get is an Extra hose from Discount or something and run a T line. from the right side of the rail to the FPR and then another one to the TANK.?

 
Rep Power: 0

situate your fpr on the other side of the fuel rail, and run a return line to the tank from there. come on now, i thought you knew your shi-t....

another argument? i was just letting everyone know how your fuel system is setup and how it works since you dont even know, thats why your asking us those questions. dont ask us, go ask your mechanic who installed it for you.

if you wanna do a return fuel system... take the old OEM FPR in the tank replace it with a better, stronger FPR get rid of the OEM piece of crap... change injectors to a higher flow... and you are done...

i know you wanna do things the other way... but the other way is untested and not as credible... do it the right way ones... it might be expensive and not unique... but it's safe reliable and proven... follow the herd...

In regards to the comments about your car running right - did you say you had it tuned? If so, what was the A/F ratio in boost? That right there will be a key piece of the puzzle in telling if your car is healthy. If the A/f is around 14 or so in boost - that's not healthy! I'm guessing that since your stock FPR is installed in your tank, you are never seeing more than 45 PSI period - and that the only reason you may be running *good* is because you have some RC310 cc injectors installed....

If you don't do a return hose, and just remove the FPR, you will damage something, as there will be no place for all of that fuel to go...

 
Rep Power: 312

That still wouldn't work - as you need a boost referencing FPR, that will add 1 PSI for ever PSI of boost you run...
