Electric fuel pump failure. Recommendation?

[Newbomb Turk]

Have a look at all the Mallory 140 failures on the net. I use a Mallory reg & it has been fine. Their pumps...not.

I will move on when you stop posting BS.

Here is the first “failure” I found. Note that the OP never did say what went wrong. Also notice that in this example a guy says his super duty maximum effort stone reliable Carter pump was doing the same thing as the Mallory pump.

I did not know that was even possible. I mean Carter, according to you has an electric pump that makes zero noise, can feed 1k hp and never fail. Who knew.

Rutro raggy there is this…


Carter P4070 Electric fuel pump failures.

 

[Newbomb Turk]

One more because I’m bored.

Technical - Carter P4070 Failure

And that was a quick search.

The bullshitter is YOU.

 

[famous bob]

I know. You know all the failures of Holley carbs and Mallory fuel pumps.

We all know that Carter is the best and never had a failure.

Got it. Move on.

not so fast my friend : I ran Carter pumps on my first hemi (drag car) they wouldn't hold up and failed , the reason I switched to holley`s at the time ...

Turk,
Of course when you start losing the argument, you start LYING. I never said Carter elec pumps make 'zero noise' [ post #51 ]. They make less noise than Holley rotary vane pumps because the motor is enclosed in fuel which dampens the noise. The C pumps came out in 1969, muuuuuuuuuuuuuuuuuch earlier than Mallory pumps hit the market. So there will be thousands of them out there. Another reason why there are more C pumps out there is because they are so cheap. The design [ below ] allows for a cheap but effective pump. Of course there will be failures, & any idiot can go on the web & find some. I thought you would be better than that....

The 1000 hp pump, Carter #4601, 16-18 psi requires a reg. I use this on a couple of cars.

Mine has been on about 20 yrs, driven weekly. For the fuel filter, I use a spin on filter from a small diesel truck, looks like a small oil filter. 1/2" pick up line to the pump, 1/2" line to the filter. [ this pump comes with 1/2" line fittings ]. All mounted near the tank. The pump is mounted behind the driver's rear wheel which shields the noise. I cannot hear the pump when the engine is running. This layout will depend on the car, chassis etc. I have a 3/8" rubber line from the filter to the reg, which is on the f'wall. I timed the fuel flow into a container & the rate was 90 gph. With the AFR correct for non-E fuel, that would support about 1080 hp.

I just showed what I found in a 5 minute search. They fail. Like everything else. So who is lying here? It’s YOU.

Because you can’t tune you bash Holley carbs. Your answer is not to teach people how to tune what they have, but to just put a Carter on it.

Im not married to any brand like you are, or for that matter any writer of books with no practical experience in the last 30 years.

The liar is you.

 

[fishmens67]

There isn’t a Carter pump out there that will support 1k hp

A pump with a 1/2 " inlet and outlet is required at 1k hp, may as well go to 5/8" at that time.
It's best to start thinking about going to 1/2" @ the 800 hp level.
Bends, length and fittings in the fuel system must be taken into consideration

 

[Bewy]

Turk,
I can, & have, tuned Holley carbs. I choose not to if I can avoid it. And I NEVER said Carter pumps NEVER fail. Moron.

 

[Bewy]

Fish,
The flow test I described above was done with the minimum amount of fittings. As it is well known that bends, fittings reduce flow. Also the reason I used a larger filter was to reduce pressure drop/flow loss. All those fancy polished fittings look nice but you pay a price in flow. My engine doesn't make anywhere near 1000hp, but I wanted to make life for the pump as stress-free as possible. You are probably aware the rule of thumb that at WOT an engine needs 0.5 lb of fuel per HP. Since the Carter pump is outputting 16-18 psi [ not 6 ], it has plenty in reserve to overcome G forces

 

[Newbomb Turk]

The best, most reliable inline are Carter, Carter or.....Carter. The only external pump that I am aware of that:
- has the fuel circulating through the elec motor section
- which lubes & cools the brgs
- because of the all-in-one casting [ between pump & elec section ] has NO seal to leak/wear out
- was on a daily driver for 19 yrs. Replaced, not because it failed, but because the owner thought it had earned it's 'retirement'.....
For up to 500 hp, use the #4594; over 500 hp use the #460X [ two models to choose from ]
- first released in 1969, design has not changed.

One of the biggest pump killers is putting HUGE pumps [ like 400 gph ] on an engine that only uses 50 gph.

Here you go. The most reliable is your opinion moron.

They are no more reliable than any other pump.

Your claim that the Mallory 140 pump fails at alarming rate is bullshit. In terms of pumps in the market the Mallory 140 outsold the Carter like 8 or 9 to 1 when I was keeping track of it.

And that was in just my area. When I asked about it across the entire region (because when I use or suggest something and because you aren’t the only Carter fan boy out there) it was the same.

So you can continue to barf out bullshit and call me a moron but it takes very little time and less effort to research the truth.

How does using more pump than you think you need reduce the service life of the pump?

That’s a legitimate question.

 

[Bewy]

Nothing from you is legitimate. Work it out for your self.

What I am seeing on the net, just on page one, is Mal 110/140 2nd pump failure....by at least two people. Had I expanded the page I am sure I would have found more....

When you outsell a product 10:1 the failure rate will look higher.

Here is the fact. 95% of ALL here pump failures is end user inflicted. The higher the output of the pump the more critical the power to the pump becomes.

So you can ***** about pump failures all you want. It’s very rare it’s a pump issue, regardless of the name on the pump.

That’s the fact.

 

[fishmens67]

Constant12v output power, no fluctuation.
Fluctuation is a killer

Exactly.

I've been looking but I haven't really found a good answer. I am running a magnum smallblock with the magnum serpentine belt. I've had 3 Inline electric pumps fail in less than 2 years. 2 generic electric pumps and an edelbrock. What is a quality inline pump that isn't going to die on me within a year? I'm running an edelbrock carburetor. I read that the edelbrock inline pumps were garbage. Is anyone else running an electric pump with the magnum serpentine belt?

I’m running Edelbrock’s electric pump without issues for *I Think* 6 years now?

The pump I have is not the basic in line unit but the one that looks like the other high pressure/flow pumps for F.I. No pressure regulator needed.

 

[TT5.9mag]

I’d say 95% is light. If I had to guess it would be up near 98%.

I was trying to be nice(er) so people who feel a certain kind of way don’t get butt hurt.

Certainly 98% is closer for sure.

Facts are facts. And for some reason people have a hard time installing anything without butchering (enter any number of things here, wiring, plumbing, routing, etc) them. Hacks are everywhere.

I just used the inline pump. I think I saw Rusty say they were crap. So I'm chalking it up to that and doing everything I can next time around to make it work the right way. 10 guage wire, relays, return lines, the works. The in tank pump actually looks amazing and simple. I might actually do that instead of trying to mount an inline pump. I have a few months to think about it.

 

[Ironmike]

Put the pump where it belongs. In the tank.No more troubles.
