Electric fuel pump help

[JCD 59]

First off I apologize for not being an electrical guy but I need some step by step help for dummies.

I disconnected my fuel line as I was having some problems starting my 312-8, thought it might be an old hose but the hose looks and feels new so I reconnected it and now I can't get my tractor to start at all.

I think the fuel pump may be the problem,  

I'd like to change it out for an electrical one but don't know anything about them, what pump should I get (I'd prefer just to buy one from an auto store and not wait on shipping)  and how do I hook up the electronics to turn the pump on when the key is in the run position and off when the key is off.

 

Thanks,  Jim

@squonk has a number he can recommend for Napa.

 

 

I've only hooked up one and I put it to the light circuit on purpose. That way you can't forget it on.

 

 

Here's a thread with some useful information about all types of fuel pumps.

Need to know what engine model/spec number you have or tractor model number if the engine is original to the tractor.

Some have AC power to the lights

Some have DC power to the lights

Some have battery ignition

Some have magneto ignition.

Facet low pressure pump. Carbole or Mr. Gasket are the exact same pump. Napa # is 610-1051

You might want to take the hose off the carb and crank the engine to see if there is no fuel flow before getting a new pump.

I recommend the faucett 40177 electric fuel pump, very low psi usa made and not plastic.

I wire mine to the I terminal on Battery Ignition units .

S/G or else stator with regulator or diode -- DC

Stator without diode or regulator -- AC

Yep yep 10-4.

 

Now that I think about it the Workhorse we built would have originally been an AC system but all of that was modified or gone before we got it.

Missed one

Magneto ignition using a battery type of ignition switch plus a kill relay to control the magneto ignition

 

Careful consideration required to connect an electric fuel pump..

If in doubt ask questions.

Thank you guys even though I could only follow a portion of what was said.

I finally got my 312-8 to run so the fuel pump isn't shot but I still wonder if its weak.

I'll keep reading and probably try to switch it over to an electric one soon.

Thanks,  Jim

Jim, here are a couple of threads I did when I installed an electric pump on my C-160.

 

 

 

[Mike in NC 341]

I installed an electric fuel pump on my Bronco 14 several years ago. I wired mine up to a toggle switch that runs a relay to power the fuel pump. I used the Mr. Gasket 2-3 PSI pump.

@JCD  personally like the CARBOL  electric pumps , also put in a single LED green bulb in the dash to verify it is on / off  , you didn't  mention cleaning tank or , possible carb fuel bowl  packed with  debris , very easy to do . between  debris in tank , and fuel hose break down , the carb issues can be a regular thing . also have 2 fuel filters on my horses , 1 large  filter close to tank , another small one , close to carb . my pump light comes on with key switch start , pete

Carbole, Mr.Gasket, Facet, they are all the exact same pump with a different brand name attached.

The hour meter on your 312 has fuse protection and is only powered when the key is on so that is a good source of electrical power for the fuel pump. The pump should be located lower than the fuel tank so it has a positive suction head pressure and doesn't have to suck the fuel.        You may want to go ahead and buy the pump along with new hose, clamps and a filter so you can do the job at your convenience rather than when the mechanical pump decides to let you down.

I went back and looked through those threads of yours. Was there a particular reason you chose the location that you did for the fuel pump to set? Or is it just a matter of convenience?

Near the tank, under it and easy to get to.

Carbole pumps are made in China..Facet are made in USA

I stand corrected. Same body and look though.

I would guess Chinese clone like the Honda small engine knock offs...
