So, is this anal or what?

[my427cobra]

Love the look of those old Stewart Warner 240-A fuel pumps from the 60's. Bought a few on e-bay over the years with the thought of rebuilding them. Even with the available parts on-line and the excellent instructions on the GT40 forum, the pumps I bought were beyond rebuilding, mostly due to bad corrosion.

I really wanted to mount a pair in my trunk, even for "show", then I got thinking. So with a little on-line research and some inventing, I got an idea.

I gutted a couple of the pumps and mounted a modern inline electric fuel pump inside and fashioned some prototype "plumbing" and voila - see pics.

I'll nickel plate the top and bottom pieces, paint the body the right color (?) and do the plumbing in stainless.

The result should be two working, modern inside, vintage looking outside, pumps.

Now that is anal !!!!!!!

Anal, yes, but sweet none the less.

I agree with the anal thing but relate big time,the wife says that of me all the time.For me it has always been that if it don't look right then it is not.For what little effort it takes to make it look right the reward everytime you look at it afterward is worth every second of time spent making it that way.

Thanks for the comments guys.
Next week I'll get the stainless lines done (so it won't look like home plumbing), get the bodies cleaned and painted and send the bits and pieces out for nickel plating. I'm using 1/2" ss lines to plumb it and this may be overkill (3/8" would probably do) but I figured a little more volume to my 2 -4bbl manifold won't hurt.
These electric pumps put out 30 gph and 5 - 9 psi each (the original SW pumps put out 60 gpm and 8psiadjustable down to 4psi), so they should be adequate for performance driving but maybe not enough for any all out competition.
Although when the racing Shelby Cobras had two in the trunk, only one was used at a time. One used when racing on a full tank and the second switched on when the tank was low to catch the fuel as it sloshed around.
I'll be using a regulator and return fuel line and I'm drawing from the tank througha Russell billet in line fuel filter (40 micron).

Back to the workbench.

Actually both were used at the same time.

The Comp cars had a mechanical pump for normal fuel flow, and the S-Ws were turned on to pump the reserve.

Thanks Computerworks for keeping the history correct. Any idea why they would have used the electric pumps and the mechanical pump?????

...simplicity.

No gauge.

You raced till it sputtered, then flipped on the electrics to get to the pit for refueling.

What's wrong with the cool vintage look? Fix the plumbing and install...

I like anal.

[lovehamr]

That's pretty sharp!

[Buzz]

That's craftmanship. And attention to detail. That's the sort of thing that raises a nice Cobra up another level and makes it a work of art. Looking forward to seeing the finished pics!

Thanks for all the positive comments guys. I wasn't thinking in my earlier post when I said I would paint the bodies. What I should have said is I was going to clean them and alodine 1201 them (aircraft alodine) and restore them back to their original golden color. I'll try to match the color to a pair of original (untouched, not used,NOS) pumps I have.
I'm going to test mount them in my trunk and post a pic.

[wolf k]

Any photos of how you secured the new pumps inside the old housings?

[my427cobra]

Hey Wolf K. Are you trying to steal my secrets??????

Just kidding. I'll take some pics tomorrow morning.

Not anal and damn creative! Done right, only your hairdresser will know I could even make the argument that every "replica" out there fits in the category of "modern inside, vintage looking outside".
