Expert 5K+ Posts: 8947 Location: WHEELING,WV.>>>HOME OF WWVA | if i were going to use a fuel pump something like a holley red , where would be the best/safest place to attach it . i'm thinkin under the hood might not be the best place but might end up being the best place -------------------------------------------------later | ||

Expert Posts: 3575 Location: Netherlands | In the trashcan. Use a Carter fuel pump. It's quiet and doesn't need another regulator to control the irrational output like those Holleys produce. Fuel pumps in general are better at 'pushing' the fuel forward, not sucking it up. They also don't like heat. So the 'best' place is usually near the fuel tank. | ||

Expert Posts: 2490 Location: Kansas City, KS | I've been using this E8012S for the last 4 years on several of my old cars https://www.ebay.com/itm/271993256488 It's not super quiet (as noisy as most typical external elec pumps) but it's super cheap and readily available. Currently $12.50 shipped! I mount them on the frame rail as close to the tank as possible | ||

Expert Posts: 3775 Location: NorCal | My '56 Plaza had the E8012S pump and it failed early on so I replaced it with a Mr. Gasket Micro 12S and so far so good. I can't hear it with the engine running. (Fuel Pump.JPG) Attachments ---------------- Fuel Pump.JPG (178KB - 619 downloads) | ||

So why not use a mechanical? They easily make 6psi and anywhere from 90 to 150 gph. | ||

Expert Posts: 3575 Location: Netherlands | I've used these Carter electrical fuelpumps over the years with good succes. But there's nothing wrong as such with a stock mechanical pump. Quite a bit safer as well, as when the engine stalls for any reason, the fuel supply stops. It doesn't stop with an electrical pump. Kinda a bad thing if your car happens to be on its side in a ditch or in a carcrash for instance... Edited by BigBlockMopar 2018-08-30 2:38 PM | ||

Expert 5K+ Posts: 8947 Location: WHEELING,WV.>>>HOME OF WWVA | the biggest reason is my dart might not move for a month at a time , without being started in between and the bowls are dry in a couple of days . i'm way past my share of priming carbs --------------------------------------------------------later | ||

Expert Posts: 3577 Location: Blythewood, SC | Chuck, all of these pumps are designed to push the fuel and not pull. If I were you I would try to mount in as close to the tank and below the fuel level as I could. I have been thinking about adding a small electric pump to prime the carb for the same reason. Also, since the Demon is a Holley style carb, shouldn't it need 7psi? That's what Holley recommends. I realize that a Demon is not a Holley, but it is a Holley style carb. I thought about wiring it to the starter side of the solenoid so that it would come on only when the starter was engaged. Then the mechanical pump could take over once the car fires. Obviously with an appropriate fuse and relay in the circuit. Thoughts? Edited by 57plymouth 2018-08-31 9:07 AM | ||

Canada - Rocky Mountains | 60 dart - 2018-08-30 10:04 PM the biggest reason is my dart might not move for a month at a time , without being started in between and the bowls are dry in a couple of days . i'm way past my share of priming carbs Some useless info Chuck. My last four builds I have had a auxiliary electric pump for that reason (fill float bowl after siting and as a backup) along with the mechanical pump . With that combination I think that you have to have a pump that is designed to be used as a auxiliary with a flow through design when not operating. Works great, run electric until it thumps, fire up engine, really works well. My first build I used the Carter P4070 (?) rotary pump as a auxiliary, bad move, the vanes could stop in such a position that blocked the fuel flow!

Obviously with an appropriate fuse and relay in the circuit. Thoughts? the demon story i got directly from holley is that the street demon was in the building refining stage when holley bought the barry grant carb operation , so they just used the demon name from there . if you search youtube you can see the gist of the street demon . copy and paste directly from holley; Fuel Pressure Demon recommends between 5 and 6 PSI fuel pressure at idle. Gasoline carburetors can be run either at idle or wide open throttle at these pressures. Be sure your fuel delivery system is properly adjusted and able to maintain volume flow at these pressures. Improperly adjusted or inadequate fuel delivery will result in poor performance and possible engine damage. i've also thought of using an electric as a prime pump . i just aint put nothin in stone yet . at this point i don't know when i'll be gettin my machined parts back . but , i do know he's 3 months behind! -------------------------------------------------later oh as a psss , the mini edelbrock pump is a push , pull or a transfer pump | ||

Expert Posts: 1208 Location: SWITZERLAND | "Works great, run electric until it thumps, fire up engine, really works well . . . ". From an engineering point of view the serial configuration of two fuel pumps is a nonsense. One "loads" the other and the weaker pump governs the maximum flux. Other when configured in parallel as shown in an earlier thread. The stronger pump then defines the maximum flux. When one pump is off, this doesn't influences the other pump which then work In an mechanical - electrical analogy this is simply confirmable. This doesn't means that a serial pump configuration will not work at all . . . . - SERGE - http://www.forwardlook.net/forums/forums/thread-view.asp?tid=23691&start=56 | ||

One "loads" the other and the weaker pump governs the maximum flux. From a real world point of view, as mentioned in my post, not if the auxuilly (primer) pump is shut off after the engine starts. Then only one pump is operating. | ||
