What would you recommend for electric fuel pump pressure, 4 - 7 psi or 2 - 4 psi? I'm looking at Facet 6101077 or Facet 6101078. Both pump 32 gal/h. They are available at NAPA.

I put a Carter P60504 (inline) pump on my 59 Lark, 259. While it's had many different carburetors on it over the years, it's back to its original 2 barrel right now.
And yes, this pump worked well with a Carter 600cfm, an Edelbrock 500cfm (most of the time I've owned the car), and a couple other experimental trys.
This pump is very quiet as far as electric pumps go. It even comes with a fuel filter. A very simple installation.
Been on for a few years now, very happy with the results.
Be wary of any pump with small (1/8 npt) fittings. While they may offer "pressure", the tiny fittings do not offer volume, which is what the carburetor needs more that pressure while under a load.

1/8 npt thd. is standard for 5/16" line. Fuel pump and carb both have that size. I have 1/8 npt on my 289 4bbl. Hawk and have never had fuel starvation problems. I also had 1/8 npt on the mechanical pump on a 322 c.i. Buick with 3 2 bbls. and had no problem. Good luck- JimComment

Kinda like putting a Cadillac intake manifold, without a LOT of rework on a Stude engine.
Will it work, yes, will it work as well as it could, no.
I stand by my comment, why squeeze the line volume down from 5/16" dia. down to less than 1/8" dia. (1/8" being much smaller than 5/16") Makes no sense at all to me.

Don't forget that tubing and pipe are not measured the same. 1/8 pipe is .261 inside diameter."In the heart of Arkansas."

There is an easy & popular upgrade to fitting various aftermarket electric fuel pumps to your Stude, its called "rebuilding your original mechanical pump"!! I don't know why more people don't buy the kit and make their old Carter pump work as new again, its a reasonably easy pump to work on and there are some sensibly priced kits out there with quality diaphragms. The original pumps had none of the reliability issues we are hearing about now. There seems to be a misconception here.......

Excellent choice! I have ran Facet pumps for many years and many miles, on several Studes. Simply cannot go wrong with them. They also will draw, to a point, and gasohol and other junk will not hurt them. I suggest the 5-7 PSI, and you likely will not need a regulator. If you think you do, its easy enough to install later, but I doubt it.Originally posted by oldguy_46ca View Post
BTW Mike, perhaps you do not know the 1/8" NPT has an inner ID of 5/16". The 1/8" is talking about the external pipe thread, and I do not know why they call it 1/8" since that size does not apply to any dimension anywhere. Of course, if the ID were 1/8" it would not work, and it would be like a human trying to breath through a straw. As mentioned, the 1/8" NPT fitting's ID is 5/16", so it is a perfect fit, since most V8 Studes originally came with 5/16" ID lines.Comment

Yep, that's the one. You will want to mount it on two rubber isolators, or else the vibration will be annoying. Once mounted on rubber, it is quiet as a mouse. Be sure and run the ground wire to the bottom side of the isolator. I use these: http://www.ebay.com/itm/4-Rubber-Vib...UAAOSwu4BVw994Originally posted by oldguy_46ca View PostI'll get the 5 - 7 psi model.

The only problem I've ever had from any electric fuel pump on any of my cars was too much pressure causing flooding. I would recommend the low pressure version. It should be more in line with the stock pump pressure. With the Facet pump, definitely mount it on rubber, they're quite noisy when mounted solid, one reason I don't use them. I use a Toyota electric pump on mine, it's very quiet mounted solid. It works fine with or without the stock pump in line with it for the stock AFB. It's max pressure is 4 lbs.Comment

I'm also leery about too much pressure. So maybe the lower psi range will do. Thanks for the mounting tips.Comment

"First, verify, with a fuel pressure gauge that the pressure does not exceed 6.5 psi."
