Fuel Injection on Early Model Mustangs

Racin Randy · Jun 16, 2006

I have a 1969 Mustang Convertible that I have put fuel injection on. Problem is that when I get down to about 3 gallons in the tank, the fuel sloshes away from the stock pickup tube and I have no fuel pressure. Aside from putting in a completely different tank with an inside surge tank, or a drop down area to collect the fuel and extend the pickup, has anyone had experience with adding a fuel pump 'sock' to the end of a stock pickup tube? I've heard about this, but never tried it. If so, which sock did you use, and also is there such a thing as a 2 headed sock with it going to both sides of the tank?

Thanks
Racin' Randy

I think the sock only works as a pre-filter, sorta. I doubt it would help much with fuel slosh. I think you really only have two choices:
1)baffled, sumped, or foamed tank.
2)keep more than 3 gallons of gas in it, lol.

If your interested I have a new Header Tank that I bought from a fellow
Mustanger I would sell you. I was going to put EFI on my Mustang and
I finally have my carb working good so I never used it. Its All plumbed
and ready to go. I also have new pumps for it also. There is a pump
in the header tank and a pump between the fuel tank and the header take
to keep the header tank full. If your interested send me a email

Sock

Well..................someone, somewhere, somehow, sometime told me that the sock has properties that suck fuel in even if only a partial amount of the sock is submurged.

A surge tank in an original tank is about an $800 option.
Fuel cell and all components is about a $1000 option.

I'm hoping for a $50 option.

Carburetor, close to the $50 option

If I were ever to do a FI tank for a early mustang, I think I would hack it up along with a foxbody one to create one that might work.

Back when I was running a stock tank I solved this problem by running a Carter low pressure puller pre-pump. It had enough volume in its reservoir (gold piece in photo below) to provide the main EFI pump with fuel during any momentary loss at the pickup. I've since gone to a Fuel Safe with surge tank but mostly for safety reasons at the track...

My solution to this problem, keep the tank above the 1/4 level. I decided to go this route for now with my install, I am hoping that someone steps up and offers a tank with an internal pump and baffling that doesn't cost an arm and a leg. This one is real nice http://www.rickshotrodshop.com/ but the cost is just beyond what I can justify right now.

As shown above, the catch tank and low pressure supply pump is an option.

That photograph could almost have been taken from underneath my car - same low-pressure pump, except that I'm running it through a header tank. Is (or was) that Carter pump super-noisy? It's been reliable, but I can barely hear the Walbro high pressure pump in comparison. What's your experience? Sorry for the hijack...

Do a google search for "surge tank". This would work well for you, only problem is that you have to run 2 fuel pumps....

Ronstang · Jun 16, 2006

I took a different approach. I don't like header tanks because they are simply too much clutter under the vehicle and I don't want 2 fuel pumps because that is just one more thing to fail and leave you stranded.

I prefer intank pumps because they are much quieter and are a cleaner install. I modified a 1970 tank to gain the extra volume since I was going to the effort. The baffle is patterned loosely off of a Taurus and I can use any production/aftermarket pump that fits a Ford. You can see it here:

The nice thing about this setup is I can change a fuel pump in less than an hour without laying on my back with nothing more than a few hand tools with a near full tank of gas.

I've got one of the 110 gph pumps and oh yea, it's noisy. Everyone has a confused funny look on their face when I turn on the ignition. They just can't figure out what the hell that noise is.

You're right it's been extremely reliable, 13+years.

Sorry, but your photo link is empty. I'd really like to see what you've done...but yahoo says "no pictures".

Thanks!

Ronstang · Jun 16, 2006

Try the link again. It is fixed now, sorry.

Ronstang, that kicks ass!!!

That's a lot of time invested, but it sure came out purty!

I was going to purchase one of these as soon as I allocate money for it. click on rosehill performance products, then click on header tank. very neat kit he offers

Booksix · Jun 27, 2007

Hey Ronstang... I know this post is sort of old, but your picture link on yahoo is empty again. I really want to see what you put together... could you possibly repost the pics? thanks!

chepsk8 · Jun 27, 2007

Randy,

Pics! What color? We have a small, but dedicated crew of 69 'Vert owners here.

On my FFR Cobra, I mad a custom pick-up that was just above the fuel tank floor. How a bout a custom pick-up?

BTW, who's FI?
