My header tank is plumbed like jcomp's, return feeds into the header tank, with a dedicated return to the main tank. I dident trust the "T" to return enough fuel to keep the header tank full.

I agree. I know there are a lot of them out there like that and they run great but I wanted a more positive control of the fuel flow. Plus, this way there isn't another hose going from the T fitting down to the filter assembly.
I had also considered building the surge tank out of AN hose. A three foot section of 3/4" ID hose would hold approximately a quart of fuel. The lower end of the hose would have been feeding the high pressure pump and there would have been a couple of T fittings at the top for the return, etc. It would have been very durable but also VERY expensive. -12AN hose itself isn't too bad but the $60 fittings (each) really drive the bill sky high.

Anybody ever run an EFI setup without a surge tank, and if so, what were the results? I know that the RMP setup doesn't use one and the Mustang's Plus writeup didn't mention one IIRC. FWIW, my Jeep doesn't have much of a sump in the tank (I've had it apart) and I've put it through some pretty severe offcamber and climbing situations and have never had a problem with starvation.
The reason I ask is that the fuel system is the last order of business for me to resolve before starting my swap.

It's not my thread, but my EFI swap is done and working like a champ! I'm not using a surge tank, and so far, I have not encountered any problems. I don't think I've had the tank below 1/4 full, but I do have a 20 gallon tank.
I am doing an EEC-IV EFI swap in my 67. I have a 95 5.0.Am Using an Explorer Upper and lower intake. AODE. I guess I cheated a little. I bought the RMP complete fuel system, Painless 5.0 wiring. I work on autos all day for a living and wanted to make it a quicker swap once I get started. I am also using a Bauhman Trans controller. I like the AODE by not having to work with a TV cable. Plus I can control the shift quality and timing with a laptop.

Need some advice on installing an AOD behind a 5.0. I just bought a 91 AOD that's been sitting for 5 months. How do I service the torque convertor before installing the trans? pull it off and fill it? how much?
