Fueling & Injection - Question about using stock feed as return

Hey all,

I am thinking about using the stock feed line as a return. If I do that, do I need to remove the stock filter and use some fittings and a line to replace it, or can I just put a new filter in there so it doesn't backwash all the junk out of the current one? I'm not sure if the stock filter is directional, if it can be turned around, or anything like that, and I'm not at home to look at it at the moment.

Thanks in advance for any help. :)

just put in a fresh filter and you are good to go

dont forget do something to hold fuel pressure!

What needs to be done to hold the pressure isn't the regulator taking care of that part?

Not if you use the feed line as a return line. It "T"'s back by the fuel filter and thats where it gets retruned and where your regulator is at. So, if you reverse that, technially youll have it "T'ing off and one line going to regualtor and one going to where the pump use to pump out of.

The tee should be blocked off and the regulator inside the tank should be removed. I was talking about using a front mount regulator to hold pressure up front.

Thats exactly the way I have mine... I did not remove the stock regulator though as I have a -8 line going to the tank via bulkhead fitting.

Using the stock return line was too small and it wouldnt regulate. As soon as I added the -8 (or maybe -6, I dont remember) I could adjust my pressure, still using the stock feed line.

There isn't much diifference in the stock feed and a -6 line. For a return that would be plenty. Its just returning fuel back to the tank after the regulator. If the t was blocked off and the regulator was removed then it should work just without any issues. If not then there is some other issue that needs to be resolved.

If you block off the feed side of the tee then you wouldn't need the stock filter.

What size is needed to block off that tee?

so im confused can u the stock feed for return if u jus block off the T?

you could use it without blocking it off really... just depends on what you are doing inside the tank.

just maken sure i have this right but all i need to do to make the stock feed a return i just basicaly can run a hose off the line on top of the tank down along the pumps right?

ill be going to a braided -8an feed, now how are you guys attaching the big an fitting to the sending unit?

at my work we sell rolls of the factory plastic 3/8 fuel line i was thinking of running that instead of useing the factory metal for return to save a lb or 2

my car is a 98 with a plastic tank swapped in it from the previous owner so im not sure whats all on the insides

heres my crappy pic to make sure im understanding 100%

yes, some people choose to eliminate the old return line from the TEE under the car as well.
