Carter 4600 series pump. The most reliable external pump made.

 

I cannot disagree.

 

This one is 380 LPH. Is that not close enough?

I ran one of those for awhile until it died after 6 months 90 miles from home.
Noisy little mother too, even rubber mounted.

 

Was it a bonifide Carter? That's unusual.

 

First time in 45+ yrs I have heard of a Carter elec pump failing. Without more info, the cause of the failure may not be the fault of the pump. A pump inlet blocked with debris would see no fuel reach the pump & burn it out.

 

Yea I was out of town 90 miles from home when the car hiccuped a bit and a glance at my AFR gauge showed 22/1 for a couple of seconds then recovered.
It did the same thing 3-4 times as I was headed to the car show I was going to.
Once there I walked over a block to a place and bought a new Holley pump to toss in the trunk in case I needed it on the way home.
No problems driving home, but I obviously couldn’t trust it after that.

The fuel system was absolutely clean as was the filter that came with the pump.
It was mounted as recommended with a relay to power it so it had a good 12v supply as well.
My fuel supply system is 3/8 up and a metered 3/8 return, so the pump wasn’t under any particular stress from dead heading either.
(Not that it should matter to a rotary vane pump)
Not a single glitch after replacing it with the Holley pump.

 

Which Holley pump did you get?

 

I just got a basic 38 gallon hr. Mighty Mite.
Afterwards I took it out And pinned the throttle on a long straight while keeping an eye on the afr.
It stayed normal and steady, so I figure I don’t really need more than that.
Side note: 140 mph according to the gps.

Now the armchair racers can bitch because I didn’t get a 300 dollar pump. (That by the way would also probably also die in some town away from home) LOL

 

Just going to ask if you are looking for efi/ hi press or what

Walbro seems to have a fair reputation, I cannot speak from long experience

 

No experience yet but I have two of those on my build. Have primed it and its kinda loud, even mounted in a isolator clamp type, might add some rubber between the double mount and the holder.

 

Just wondering, is this for your nitrous upgrade?

Its a staged set up controlled by the megasquirt.

 

Then get an Aeromotive. Never a problem with them. A 1000 series or a 2000 series. Kim
