Fuel Return Line?

Well, i went out and bought 14ft of fuel hose, as well as fittings, and now my only question is this: What do i need to modify in the pump housing to complete the return assembly?

I tapped the top of the housing and put the fittings in, but where do i need to run this line to? I've tried searching, but anytime i click search, or go to advanced search, i get the good ol "Server is too busy" message (webmaster, you gotta do something to fix that, its been killing me lately).

Any help you folks can give me would be greatly appreciated.

Also, i have a bit, i have a tap, now how do i get access to the damn drain hole in the motor? Drop the pan and do it that way? Lemme know folks.

Here's what you need to do to the fuel pump assembly.

1. Drill a hole in the plastic fuel pump assembly.
2. Get a bulk head fitting and install the fitting on that new hole.
3. Install the return line from the FPR to the end of the fitting that's exposed.
4. The other end of the fitting that will be in the tank needs to connect to the white ventricle.
5. Cut the line that's connected between the stock FPR and white ventricle.
6. Either pinch the nipple that is now exposed on the stock FPR closed and weld it shut or get 1/4" fuel line, 1/4" bolt that has no threads on the shoulder. Cut off the threated area of the bolt, insert the bolt in the 1/4" line and put a hose clamp on it. Put the other end of the rubber line on the stock FPR.
6. Run rubber line from the bulkhead fitting to the end of the white ventricle that the stock FPR was connected to.

Tap the top front of the rail and put in the fitting. Then from the rail the hose goes to the FPR. Then from the FPR the return hose goes back to the pump assembly

alright, what do i do to those? Im guessing 3 is the one i pinch shut and weld tight?

What about 1 and 2, which of those gets the return hose?

Thanks again for the help.

from the explanation, you simply 'take out' the stock fpr out of the equation - so your return lined needs to go to the rubber line that the stock (oem) fpr was connected to (#3 in ur pic)

Never argue with an idiot; they'll drag you down to their level and beat you with experience

And if I remember right the line coming from the passenger tank hooks up to #1

1. Connects to a rubber line that's in the tank already, leave that alone.

2. Connects to nothing, leave that alone.

3. Snip the black line, close off the end of the stock FPR. The return line should come through the hole near the Walbro pig tail then connect to where the stock FPR was connected to.

I assume all of you who have done it this way don't have problems with getting fuel from the other side of the tank? TE's setup requires a few more tweaks (drilling out jet valve larger, and flipping the nozzle contraption that you guys are talking about) but it obviously didn't work well that way.

I didn't drill the hole bigger, I don't believe I have any problems with getting fuel from the other side of the tank. I can look again later on during the spring.
