I am running a Carter mech. strip pump on my pump gas small block, 3/8 line and autozone fuel filter.I drove 40 miles round trip to the last race and ran my new best of 6.29,1.33 60ft.@ 108 in the 1/8 so far. I hope to have the fuel system upgraded by spring so I can put my 1050 carb. on it.

I just use the Holley black pump and the stock tank. I put a 3/8 sending unit in my stock tank and run 3/8 line in the stock location. Pump and filter mounts back by the tank. And I use a pump block off plate where the mech pump was. Works fine for 10.70's and still pulling good thru the traps. Ron

I also run the carter strip pump, with the stock 5/16 line from the tank. My fuel pressure guage isn't visible from the interior, so I don't know exactly where I'm at, so I guess I'm no help. I haven't experienced anything that suggests I'm running lean up top, but I plan on moving my pressure guage to the cowl this winter so I can keep an eye on it.

Rick Eherenberg sells one for a very good price at the bay. 3/8" all the way.
built in pressure regulator. he claims it is good for 700hp. ordered one
but it is not delivered and installed right now.

I have used the racepumps pump for a 650hp sb without problems.
Said to be good to 2000hp!
Only problem was when ran out of fuel. Hard to get it pumping again had to prime it.

what is the application? Carter and Holley make good street pumps, I ran an Autozone replacement on my old 440-6 (11:1 528 solid cam, 1.5 rollers, headers, 3800 stall, 3.91's). Worked just fine. It all depends on how much gas you need.

I've ran a Carter strip pump into the 10's with a tunnel ram in the past. Right now I'm using a Clay Smith pump and love it. It needs a regulator, it needs to be clearanced at the block but it pumps a lot of gas.

Interested in this one as well, thinking about an upgrade to my Carter pump since my MPH and pressure is falling off on the big end.
I was actually going to experiment with a small electric booster pump in parallel with the mechanical (since i have a second/unused supply line from the tank all the way to the motor) just to see if it helped before re-thinking the whole system.

yeah like I said and? I've seen guys w/ 12.20 "strip cars" and 10 second "street" cars. In any even the carter and holley pumps will get a BB car well into the 11's w/o an issue, even w/ tiny 5/16 line.

carter strip pump with regulator, 10.60. still shows 6psi at the stripe. it gets driven a couple thousand miles a year, is about 15 years old, and has been stone wall reliable (as opposed to numerous failed attempts at electric pumps).

CV makes a billet pump for Nascar that fits bb that i found and i gues that that would be one of the nasty once that will need a regulator but i havent tryed mine yet !

Evan back in the early days we ran Carter mech. pump with electric in the back. Someone want to race just flip the switch, didn't have to put up with noise all the time.

Re: Sreet/strip guys...mechanical fuel pump?? - 12/04/13 08:35 PM
Has anybody ever run a small parallel electric pump (like the Mr. Gasket 12S ~ 35gph) as a booster? They also help a ton with hot starts to refill the bowls on a mechanical. It was a fairly common hop-up for running 50-100 shots in the early nitrous days when things weren't all high-dollar sophisticated like today. I used to have one of those old "Chinka-Chinka" Dupree's that I used to cut on with my N20 "armed" switch 
You can also use it as a 'jockey' (for you firemen and fire protection guys out there) pump with a return loop. I used to put it on a 3 position switch (off/jog( i.e. momentary)/run).
BTW, they also make for a nice inexpensive "limp-in" system if you ever lose your high dollar pump on the street or at the track
@cudaman1969....that's one of the (sometimes forgotten) practical advantages of a rotary vane pump (as opposed to the more modern georotor)....you can series it upstream of your mechanical and still pull the gas through it without the electric pump running.

Wise I ran the Carter plus a cheap Summit electric in my old boosted 440. I turned the Electric on at the track or when I went WOT on the street. Don't ask what happens when you forget to turn it on.

Carter Pump -6 line 11.20s 360 with an 850 carb

Application is a warmed up 408 or 360 (haven't 100% decided yet) in a STREET/strip 69 Dart. Goal: No quicker than 11.50's in 100% street trim as it doesn't have (nor will get) a roll bar.
I have a new Holley black pump and the AN hose and fittings in stock, but not sure I want to mess with all of that. AND it would add to the "sleeper-ness" if it was a mech pump and OEM 3/8 lines.

you could probably get away with either the carter or holley mech pump and your stock 5/16 line, however it won't hurt to upgrade to 3/8, just remember to get a 3/8 pick-up as well.

I run a Carter race pump ?? and use a carter back up electric boost pump at the track..and after the car sits for a month or so It's nice to pump up the fuel without cranking the motor...and it's always there if the mech pump takes a sh--..I can get home on the electric pump..

Where would I get one of these? I run the Clay Smith pump now, like to try something different in the future.

Yep. IIRC, Dwayne Porter's 440 B-body was in the mid-to-high 10s w/ a mechanical pump and still had the OEM 5/16" line.
My only concern w/ a mechanical pump was when I was still running a Six Pack on The MoPig and had some vapor-lock problems crop up on occasion. The fuel line insulation I added to deal with the issue seemed to work, but certainly took away from the sleeper image.

There was a guy on FABO that I think worked for airtex that clames the airtex stock replacement pump will hold something like 5 psi with no drop off at hi rpms. Not sure if true but if it's a low 12 to low 11 sec car might be worth a shot, if it's starving at the big end bring it back.

Re: Sreet/strip guys...mechanical fuel pump?? - 12/05/13 11:49 PM
I think the biggest obstacle for the stock pump location by itself is over coming g-forces (the weight of the fuel) bringing it from the back, which is also the major problem for the smaller electric pumps with a big line(8-10) 3/8 line would be the max I would use. Mech and small electric pusher will work well into the lower 10s

It will work as long as you can boost reference it. I ran a hi-po carter on my old S/C'd 440. All I did was tap a small 1/4 line into the top of the pump (it's already there maybe for venting)and ran a line from the head unit to the pump.
