In-Tank Mod Question
I am going to work on doing the in-tank mods shortly. I have a buddy that works at Walbro (not TI Auto) and he can get me any type of fuel pump for free. I am just wondering what type and pressure regulations I should keep it in? I know I can put a regulator on it but I just want to make sure when I do it I am not going to over fuel or under fuel it. What is your guy's suggestions for fuel pressure?

The in-tank mods won't mess with your fuel pressure. As long as you don't mess with the fpr on the fuel bowl, then your pressure will stay the same. You will want to get a pump like this.......http://cgi.ebay.com/ebaymotors/WALBR...Q5fAccessories

If you can, go ahead and get the 5.4 intank set up for a 38 gallon tank. Then all you should have to do in remove the mixing valve, Run electric to the new pump, and extend your return line. You can remove the existing pump right out of the system.

Post Three and post Seven is what I am basing this off of.

My factory Pressure was 55psi. I shimmed the FPR to 75psi. And drove on that for a while. Recently i brought it down to 65psi. I run the CCK so it is the cheap version of the regulated return. (i played with pressure to try to get rid of my idle knock and was easly enough to try)
What is wrong with your factory pump? If you can get a new similiar pump, that is awsome. Toss in box for a spair. Maybe grab another free pump and send to your friend Danskool so he has a spair for when he travels.

After talking to my buddy, he told me that it really isn't worth going to 1/2" unless I was turning 700 horsepower so I think I am going to stay with 3/8". I also have access to the Parker Push Lok hose so I might as well use that too but I just need to know what to set the regulator too when I do it.

If he's just putting in a lift pump and leaving the stocker alone (too much trouble for any gains, IMHO) then no regulator is needed. If he's replacing the stock pump with an in-tank version, then probably. The fuel bowl has the FPR, so I would think that as long as the replacement is close to stock specs, it could be adjusted for the optimum pressure. It's MUCH easier to just replace that and go with a reg return though. I'm about to put mine on to support the injectors.
