The $65 Carter rotary puts out 3.5 - 4 psi, will feed two Weber 44idf's with no regulator on a engine (2100cc) that spends at least half its run time in full tilt mode (autocross racer), and needs no return lines, whats the problem....

Return lines are part of pressure control on Fuel Injection that run 35 - 50 psi in fuel rails.... You are getting applications and pump styles (design) confused here ....

I had my carter rotary in 2 previous cars. I just installed it in my current car, after sitting one year on the shelf. It still pumps like a champ and my Dell's love it :)

x2, the Carter aka CB Performance rotary pump is internally regulated, very quiet, very reliable. Personally, I'd choose a mechanical pump over all this electrical nonsense, but when you've got a 75+ FI case like I do, don't have much of a choice. :(

I recommend Carter P60504.

I out bid a guy on Ebay and got a new in the box Carter for $16 plus $15 shipping. Just have to install it. I did the last 30 sec jump in and bid at 1:00am.

Anyone looking at a Holley-- Red blue or black should know that these are some of the loudest pumps made...Ok for a racecar but too much for a street car

Forget the pumps at Autozone. I read several reviews and they fail like crazy.

I've had very good service from the Carter rotary pump. And it is very quiet the way I have it mounted.

thats what rubber mounts are for, and also.... if you have a problem with your car not starting, you know if you have a workin pump very easily, no putting your head underneath the car to check to see if somthing quiet is goin. haha :twisted:

Oh, i should have said this before as well, but i don't care about the noise. If it will work for years with no issues, then it can be a friggin train horn for all i care, i just want it to work. i actually kinda liked the noise the pump made. thats what told me it wasn't working, preventing me from getting stuck in the middle of the road. the second i heard that thing cut off, i dove into the nearest parking lot, sure enough, about 2 seconds after i got to the parking lot, the car died, lol.

i do plan on adding a fuel pressure guage, so i won't have to rely on hearing the pump to know if its working or not, lol.

also, i have a lead on a brand new older (made in 2005) holly blue pump. so maybe this one won't have the apperently crappy regulators. the problem is, that it says it only goes down to 4 psi. where as i hear that with webers, you want a MAX of 3psi. would i need to get another regulator? i do like the idea of getting a bypass regulator, as that should help keep the pump cooler, expecially while sitting in traffic on these hot days. i have no problem drilling the gas tank to accept a return line. i have to remove it anyway, because there is a lot of crap in there (yes i had a filter between the pump and tank). and while i'm at it, i can braze a fitting onto the tank for a return line.

the blue pump is internally regulated at 14 psi... what they call the "high pressure" regulator is for 4.5-9psi, and the "low pressure" regulator is for 1-4 psi...

I would just get the carter rotary pump.

alright, yall win, lol. i just came back from summit, and picked up a new carter pump. I'll install it tomorrow, and see how it goes. One thing thats already got me worried, is that inline filter that it comes with. it has about a 1 inch long piece of hose connecting the pump to the filter, and has these crimped on hose clamps (the kind that have no adjustment, and once removed, you throw away), but the one on the pump doesn't seem very tight, as the pump can easily spin, and i can pull it partially in and out. Scary. so i'll cut that shit off and use some FI clamps. For now, i'll just use rubber hose, but later on, i'll switch to wraped silicone fuel line. Pretty awsome stuff, and expensive as hell (over $6 a foot), but worth it, to never have to replace the hoses again for a long time.

thanks for all the help. i'll let all know how it goes.

Also remember that all lines before the outlet are not under pressure.

Mon Jul 12, 2010 7:33 pm

ok, so let me ask yall this, as far as filters go, what do yall recommend, as far as off the shelf filters? i keep hearing those little clear cheap filters don't filter very much. so are there any good off the shelf filters (as far as FLAPS stores are concerned), or should i just stick with those cheap $2 ones?

Also is there a difference as far as mounting them? Is it better to have one before AND after the pump? I've always had one after the pump, next to the carb, but never gave it any thought as to weather the filters are ment to be under pressure or vacume, or does it matter?

Mon Jul 12, 2010 8:23 pm

I don't recommend filters on the pressure end of the pump.. the one that is before the pump does a fine job AFAIAC.Any extra connections beyond the pump are a potential point of failure.
