Ok, here's the deal. I had to leave the MM in the garage for the past 2 months without it being started or driven. The person who was supposed to do this fell down on the job.

Anyway, now the fuel pump will not run unless I get under the car and tap on the pump where the fuel outlet line is. Then it runs until I shut off the car. Then, no pump running again on a restart.

The electrical system tests out fine (there is power going to the pump leads at the pump when it is supposed to).
Sooo, I am going to replace the pump.

I can't find the post that said you just have to lower the tank a few inches on the passenger side to do this. I want to check in with someone who has actually performed this and make sure I don't miss a potential problem. I have 1/2 tank of gas and know I have to drain this down before working on it.

Is there anything I should buy in addition to the new pump to make it go easier?

I appreciate any help I can get.

Heres proof you can take the pump out of the tank IN CAR.
You will have to unbolt the passenger side strap to allow a wire to get by it.
You will also need to make a tool to get the connector above the tank undone. It can be accessed through the passenger side wheelwell.

With Zack's help installing ProCharger #26 (he did MOST of the work :bows: ), I can attest that this can be done with out removing the gas tank :D

Here is a link with pics from when I swapped to a gt-40.

VM:

Zack is correct. I followed his directions replacing my fuel pump with a SVT Focus pump and it worked out just as he stated it would. (See his pictures above). The hardest part was disconnecting the electrical connector. It took a very long ice pick like tool to unhook the connector tab.

If you are going to replace the fuel pump upgrade to a SVT Focus pump. It has more flow.

Excellant everyone! Many thanks! It now seems so relatively simple.

And yes, I could not believe when I said "If you want to take the car out once or twice a week and move the lubricants" it would not be an irresistable invitation. Of course he would have had to move a couple of other cars out of the way to do it. Maybe I'll ask my 82-year-old mom to do it next time......

I can't even get my 60 el camino out anymore, who am I to judge?

Don't do the Focus pump. If you are going to swap, go right to a GT-40.

Single GT-40 or twins?

My single GT-40 supported 540rwhp and 470rwtq, but that was with a BAP turned to MAX.
90% duty cycle.

The GT40 is more difficult to install then the simple and straight forward SVT Focus fuel pump. The GT40 requires changing the electrical connector, etc. and is not as simple as the Focus. If you are going to 500+ HP then spend the money and time on the GT40. I went with Lidio's recommendation for my HP. He installs a ton of Focus pumps on blown Mustangs.

While it may be more difficult, it is not that hard and there are step by step details to install it.

Final HP will determine which set-up, but a single GT-40 is very good. I made 420 rwhp safely on a single GT-40 with no BAP. But that is with a turbo which requires less crank HP. I have a BAP now at 450 + and there is plenty of fuel left.

To do twins is a financial commitment. Two pumps, upgraded FPDM, running big wire back to the FPDM and then to the pumps, etc, if you want to do it right.

Sorry to revive this but you would not believe how hard it is to find this kind of info on the Stang boards. I joined this board just to find info like this. Thanks.

So the SVT Focus pump is plug and play? No mods needed at all?

Does it do anything better for those NA?

Part Number?

Thanks for the info.

I've heard from a ford garage that i should not keep the gas tank full when storing the mm for the winter months.It damages the fuel pump.

GT40 pump? Why are you all using a fuel pumps that are over 40 years old?

Use a Ford GT pump.

Try search for the Focus fuel pump part number - it is in an old post. Look under "Focus SVT Fuel pump".
