My '63 F-100 with the 262 i6 has an electric fuel pump located directly below the fuel tank, underneath the driver's seat. Recently I had some problems with fuel starvation at highway speeds and the fix was to replace the pulse-type Carter fuel pump with a higher volume continuous-flow electric pump, the make and model of which I can't recall. This solved the problem and the truck has been running great.

Lately, this fuel pump seems to be a lot louder! It's only a couple of months old. There is a fuel filter between the pump and the tank, but I have a hard time believing it is clogged since it only has a couple hundred miles of use, and the tank was checked thoroughly, and seems to be very clean with no sediment.

My question is this: If indeed this electric pump is going bad, what are the pros and cons of going back to the original-type fuel pump? The lack of annoying whine appeals to me.

Thanks,

The original fuel filter was located on the fuel pump itself. Either a paper or ceramic filter inside a glass bowl, or a corrogated paper cartridge filter inside a metal cannister that threads onto the pump (see post 7).

Some peeps are unaware, so they install an inline fuel filter.

My original fuel pump is gone; replaced with a flat plate on the side of the engine. My current fuel system looks like this: Tank, metal fuel filter connected with rubber hoses, electric fuel pump directly below the tank, rubber fuel line taking shortest route to carb, another metal fuel filter at the carb, then the carb.

I know rubber fuel line is not ideal but that's the way it is now, for the last two months or so. I ran this when I was troubleshooting the earlier fuel starvation issue. If I go back to original type fuel pump I will probably run all new metal fuel line using the original route.

Also, i know the fuel filter between the tank and fuel pump may not be necessary, but the mechanic who helped me troubleshoot the starvation issue and sold me the new electric fuel pump talked me into it.

 

Electric fuel pumps are pushers, need to be mounted as close to the fuel tank as possible.

If you want an original, see edited post 2. I'll have to edit again, if you want sources.

 

My question is, what are the pros and cons of original vs. electric?

 

Electric pumps are loud. Even the quiet ones are loud if they're mounted directly to a frame rail or something like that. If you completely isolate it with a length of rubber hose and use some rubber washers between the frame or wherever it is mounted, it will quiet it a good bit.
If the new pump is a Holley, it probably is dying already. They're crap. I had two that died within about 2000 miles - total, average 1000 each! They didn't get loud but must have developed a short and began to draw too much current and blow the fuse. About 3 years and 7000 miles ago I swapped to a Carter and have had zero problems.
The problem I see with the Holley is that there is no effective way to keep it cool - no fins, not submerged in fuel so for continuous daily driver use it just can't last. It's probably fine on a dragster or trailer queen - it wouldn't run long enough to get hot. I acquired the carter by ordering an electric pump for some 80s big Ford truck - I can't remember the application. Numberdummy, do you know this? I figured if something for an oem application doesn't last then Ill go back to mechanical. The carter kinda has a bowl built onto it which keeps the pump submerged in fuel and the result is a significantly cooler pump. I can't give you a number but with both Holleys I couldn't hold my hand on it while it was running - it was hot. The Carter is only warm. The Carter I am using can also be placed up to 24" above the tank so there are a lot of options for mounting.

A filter between the tank and pump is important. The instructions probably say that any warranty is void if no filter is used. The pump probably has a screen which will prevent large stuff from passing through.
I have filters with a cleanable stainless steel mesh element, one before the pump and one just before the carb. You'd be surprised the size of the stuff that manages to get into your fuel tank, even a bran new clean one. The one before the pump always has stuff in it. The one before the carb usually does not. However, I would not expect it to fill up with just a few hundred miles under normal circumstances.

 

i'v had both on my 64 but on differant engines
i can see a need for both and a good use for both
the elect was with the old 240ci that ran for two years
changed to my 292 in 1988 use the same machanical pump daily for 10yrs
no problems
yea 10yrs on the filter also

 

Doesn't a 'continuous-flow electric pump' need a T eed in line that returns fuel after the pump to go back to the tank? Pressure reg after the pump. Pulse types work because they stop pumping after pressure is achieved. YES.

 

Phil, the truck & engine were designed to run the mechanical pump 50-60 years ago, worked then, still works today

Is there any real need to feel the pain that you are because a new more modern gadget was added that was not needed?

After having used both mechanical and electric, the only benefit I see is a slightly less cluttered engine bay and more room for a turbo or something like that when electric is used.
Mechanical will definitely do all that is required for a stock or nearly stock truck.

 

What 1961/66 engine bay is cluttered with an I-6 engine? He!!, you could put two of 'em in there and still have enough room to "swing a cat!"

 

Thanks for all the thoughts guys. Now I need to decide if it is indeed going bad. It seems to be a lot louder than normal, but not all the time. I guess I'll take a wait and see for now.

 

Preventive maintenance. Buy a mechanical fuel pump now while they can still be found NOS
