I am tired of replace starters or charge battery or spray starter fluid due long crank to pump gas to carb. Most time they dry after sit 1 month.


But my mind pop I could put electric fuel pump then turn on wait 3 sec then try start.

I want know if anyone done before? How they control fuel pump pressure? What good fuel pump from any store on internet?


Question convert to 2 barrel motorcraft 2100 would it help power and torque?

 

I installed a Holley electric fuel pump (rated 5 - 7 psi) in place of the stock mechanical pump. It works great, starts like it's fuel injected and my carb doesn't have a choke on it. Like you said, turn ignition on for a few seconds, then pump the pedal once or twice and start. I will never use a mechanical pump again.

 

Dont you still need a choke with the carb even if you have a constant fuel flow?

 

thank

that why I am tired of crank it.

That great why I can test what ACCURATE mpg it was by fill FULL them empty then put 5 gals then let electric pump gas to carb instead crank engine until battery or starter died.

 

I would rather dump a little gas in the carb. Seems like if it sits that long then putting extra money in it would be a waste.

 

I agree with daddy172005 - I think it's too much trouble for the problem you're trying to solve. You're looking at the pump, wiring, a regulator, return line, and safety mechanisms (inertia switch and oil pressure cutoff switch - not required but I highly recommend both).

As for the MC2100 upgrade - I assume this is on your six? If so, it's not worth your time if you're using the stock 1 barrel manifold and an adapter. You won't really see anything unless you upgrade to a 4-barrel manifold (Offenhauser, Clifford), but by then you might as well put a 4-barrel on it anyway.

 

I have always ran a choke in the past, but this carb came w/o one and it starts fine. Even with the mechanical pump it would fire after a little cranking, the electric pump just makes it fire instantly. Mine is not a daily driver, I take her out once or twice a week so the float bowls do dry out.

 

yes it 4.9L

remove air filter everytime to put gas is too much work plus latch for hood doesn't like open.


I just like turn on then wait then start.

I believe electric pump Holly have regulator but I check.


FMC400 You say I better use 4 barrel carb? how gas mpg would be?

 

Holley Performance Electric Pumps – Carbureted Products

I thought you would like check this.

 

The Holley red pump would be all you need, and it doesn't require an external regulator, the blue pump does. My experience with Holley pumps has not been good, at least not on a daily driver. I replaced the Holley blue in my Son's 86 F150 after only 1 year (16,000 miles). I had to replace it again 9 months later, and they aren't cheap @ $120 a pop. I then went with a Carter ($75), and it's much quieter than the holley, doesn't require a regulator, and it's going on 2 years old now with not a single issue. I do have a Holley blue on my Mustang that works good, but it's not a daily driver. If you go electric, you need to mount the pump as close to the tank as possible, as they are designed to push fuel, not pull it from the tank. As previously stated, it should be mounted behind an inertia switch for safety in case of an accident, so the fuel will shut off.

 

I'm running an Edelbrock 500 CFM 4-barrel on my six, with an Offenhauser DP intake. I hit 18 mpg on the highway once, going 55. If I go between 65 and 70, the gas mileage is about 15. I need to pick up a jet and metering rod kit for it though, because my gas mileage around town is poor. With the proper jetting, I'm hoping to see about 15 mpg in town. We'll have to see.

 

Please post here when you found out.

I was think about but where would we get intake from? 18 mpg I get 19 mpg in hot summer at 55 mph for 260 miles but would like more power than 1 barrel.

15 mpg at 70 not bad. I get like 15 or less. what rpm you at 70 mph? I believe my f150 was 3,000 rpm at 72 or 73 mph.


Carter you mean they mount on engine like mine?

Ok I research on electric fuel pump but I was thought about put boat primer then pump while it reach. Is that good idea?

 

[quote Carter you mean they mount on engine like mine? [/quote]

No, Carter makes electric pumps also. You would need to mount it on the frame rail, close to the tank. It's also a good idea to mount a filter between the tank and pump, to keep any debris from entering the pump. Any dirt gets in the pump, it will destroy the diaphram.

 

Can you get pic of that?

Have lot dirty in gas so what kind filter? I am tired of Fram fuel filter keep clog but you look it clean but it shut gas not though filter.

Question I see some dragway car have those fuel filter it look like oil filter. Is that good?

 

Honestly, there's nothing wrong with a Fram filter. If your filter keeps getting clogged to the point it won't flow, it sounds like you need to pull the fuel tank and clean it. I believe there is also a "sock" type screen on the pickup in the tank. If this screen is ripped, the dirt will get by it and clog your filter. The canister style filters like you see on drag cars do work good. They have a removable cartridge type filter that can be easily replaced. I have one of these on my Son's truck, and it's made by Fram.
