Default NEED HELP FAST. Stock feed for return question

So i have searched for the last hour and i am a little aggravated. I am using the stock feed as the return and when i get to the t-block can i cap the original feed line with filter and use the stock return back to the tank if i pull out the fpr in the stock plastic bucket? This is for a 2002.

Anyone? Why does no one do this? Is there a downfall?

why are you using the stock feed line as the return?
Why not use the stock feed line as the stock return line as the return line?
Yes you can remove the stock fpr, it is held in place by the spring clip. Remove the spring clip and pry the fpr out then remove the spring clip. You will still need a fpr at the fuel rail. I would suggest an Aeromotive adjustable.

What? I already have a full fuel system sitting here. -10 feed, inline fuel filter, dual walbro pumps, fast fuel rails, and an aeromotive fpr. Nothing you said answered my question. The stock fpr and housing have already been cut out of my stock housing. The stock feed has been cut off of the plastic housing and i have a 90 degree bulkhead fitting through the top.

SO back to my original question why do people use the stock feed from the rear "T" as the return and not the stock return from there? I'll see if i can find a picture.

Let me make sure I'm understanding what you are saying:

You are using the stock, hard feed line as the return - when you get back to the T-fitting, you are capping off the portion that would normally push the fuel to the filter (since the fuel is going in the opposite direction now), and just using the part that normally returned the fuel to the tank in the back?

Then yes, that should work. I went a different route by keeping the stock feed in place (I don't have huge HP that would make me want a larger feed line) and used the EVAP as my return - I just had to run a new line from the EVAP hard line in the back to the correct location on the top of the tank, but the line you will be using already goes to the correct place on the top of the tank, so it should be less work on your part.

The only reason that I could think people would use the feed line from the pump to the return block instead of the stock return line would be that the feed line is a little larger than the stock return.

I'm running a -8 return

On the feed I'm running a -12 to the pump and a -10 on the out side of the pump to the rails. The -10 feed is for the Magnafuel 4303 (pro tuner 750) I just ordered, the pump is able to support 2000hp N/A according to Magnafuel and 99% of the people I talked to that are running that pump run a -8 return. So in short on MOST cars any return bigger than -8 is just over kill. IMHO

Yes thanks for the confirmation that it would work. It is the same size line back to the tank also. I figured it would work but just wanted to make sure it wasn't something going to cause i problem.

The reason i used -10 line is because I got a stupid deal on my fittings and lines and it was going to cost the same. So why not? I have done so much to this car in the short time i have had it that i only want to do something once. So the fuel system will be competent to whatever i throw at the car. The only thing would i have to do is pull the bucket and add a third pump which is stupid easy because i set it up to accept a third one.
