no, mine was an additional filter to stop particles from getting into needle and seat.
it was sticking after the rebuild and before the extra was added and it made a world of difference.

in terms of flow I was advised as follows :

tank -> holley pump -> filter -> holley regulator -> carb

anybody got it any differently ? any guys experienced difficulties and then changed their setup ?

if im not mistaken the filter should come before the pump to prevent particales from reaching the pump and damaging/clogging it

Kentetsu

Yep, according to the Carter instructions its filter before pump. The Holley reg came with instructions for a few different ones and for a fuel pump, they also had it laid out that way in their pump instructions.

KcKhan

would tank>filter>holley pump>filter>holley reg>carb be a good idea?

Works well. That is how Ihave both Kgrays and mine set up.

KcKhan

just got mine in the mail today, have never done this install hopefully it goes well

Hey KcKhan- dont forget to post pics of your install!

The stuff is permatex liquid thread dope or liquid thread sealant.
I'm about to make a run to pick some up from home depot so I'll let y'all know how much it is when I get back.

Kentetsu

Okay, now this is interesting. When I first installed the Carter fuel pump, I reused all of the original wiring. I noticed that when I had my turn signal on, I could hear the noise from the pump cycling along with the turn signal which made me think that maybe it wasn't getting quite enough juice to run at full speed all the time. So, today I installed all new wiring, utilizing a relay triggered by the original wiring. Not too difficult. The pump no longer changes sound when the turn signal is on, and I can feel a difference in power at high rpms so that's great. But what I didn't expect was that my pump would get a hell of a lot quieter! Now, when I get to a stop light or something, I can barely hear my fuel pump. WTF? Those of you who are complaining of how loud your pump is might want to look into this. Maybe the loud noise is just a symptom of an insufficient power supply? I don't know....

DublyDurty

Kentetsu,

That IS an interesting observation and result!. Mine is also very loud. But I'm having a hard time wrapping my mind around how more power would make it quieter??? But if it does, that's really good to know. Fill us in on the relay info, please.

Okay, I'll give this a quick go. I used a relay designed for fog lights (30 amp, about 3 bucks at Autozone). 10 gauge wire attached at the fusible link location (where power goes into the block, not out), with an inline fuse holder (30 amp fuse used) runs back to the storage bin location (wire shown red in attachment). Remove the storage bin, and you will see the wiring for the pump exiting through a grommet in the floor of the bin area. I separated the plug on the original wiring at this point (right there in the bin area) and used the striped wire to trigger the relay which I mounted in the bin area (green wire in attachment). Another wire will go from the relay to ground (black in attachment). The last of the four prongs on the relay is for the power feed to the pump (shown as blue). Which wire goes to which prong on the relay? Well, look on the back of the package for a description because they tend to use numbers which mean nothing to me on the relay itself. I thought about taking pics and doing a nice writeup on this, but was pressed for time (sorry). I hope this is clear enough, if not then fire away with the questions.

Kentetsu

Yep, definitely an increase in power now.... Pump is still very quiet. I can hear it when parked if I listen for it, but otherwise it is not noticeable at all. Weird!

I have been chewing on this one since I first saw your post, so, per your PM request, I will venture a guess. Electrical devices such as a pump needs both volts and amps to run as designed. Old wiring and connectors can reduce the final output of both by the time it gets to the electrical device. Running a fresh power wire to the pump would provide the needed voltage and amps.

So here is the guessing part. If the pump was not getting the needed amps, the supply wire would heat up, thereby reducing the input. The heating takes away even more amps as it is being used to create heat and resistance in the wire. Electrical devices only take what is needed to run in the way of amperage. If the amperage supplied is not enouigh, the device struggles to work properly. Thereby, I'm guessing, causing the pump to stuggle and vibrate.

As I said, this is a guess, electrical is not my strong suit and someone with more electrical experience or an EE background may chime in and tell me I'm full of it. I have no problem if they do as I'm a bit vexed with your rewire resulting in a quieter pump. Either way, it sounds like rewiring the pump with a clean power source and relay has produced positive results. This is similiar to the pump rewire mod for the TIIs which is one of the first fuel upgrades needed.

So it got quieter ay?

I have the same set up as you just installed, but I read all the time how loud it is, So I have been thinking about sellign it and getting the Mallory 70.

If what you say is true, which im sure it is. That would save me alot of money. I Hate loud in my car. I want to hear my enigne, not what fuels it.

slightly off subject but not...i read a post the other night about adding fuel filters in front of the carb and it sounded like a really good idea to me, but it was also suggested to change the fuel pump to a higher flow model (carter in this case).

my question is this : if i add the filters and change the pump what will the extra PSI do to my stock setup? I am running the factory pump (yes it is the original factory pump from what i can tell) and it is not only loud but irritatingly small. This is going to be one of my first serious mods to the car and i am interested in what it may or may not do to a stock setup.

You will need a fuel pressure regulator and a fuel pressure gauge if you upgrade from the stock pump. Stock pumps are very quiet.

thx trochoid now i jsut gotta save the money for the gague and the regulator...

Kentetsu

Thanks for the input T. Your thoughts are pretty much in alignment with my own on this, so I'm betting we're at least close if not dead on. Give the pump the required amount of power, and it will perform as designed. There's no doubt that the pump was starved for power before this was done. With the turn signal on, the pump would sound like ZZZZzzzzZZZZzzzzZZZZzzzzZZZZ cycling along with the turn signal. Even pressing the brake would cause a drop. Makes me wonder how much better the stock pump might have functioned if it had received the same attention....

Yeah, with the affect that the lights had on the pump, either the power wasn't getting to the pump, the charging system was weak, or the pump was on it's way out.

Aren't you running a Sterling carb? If you are, then stock pump would be inadequate anyway as it barely meets the stock needs according to Sterling and Carl. I want to say having the headlights on would really pull the pump down, but they are on a seperate circuit entirely. If they didn't pull the pump down, then the charging system is good. It's a simple process of elimination.

I'm still a bit baffled by the noise reduction, The only plausable explaination I can fathom is that the pump can now run at full power/speed and no longer needs to strain, which was causing the vibration.

Kentetsu

The charging system is fine, headlights never affected the pump (which is a Carter). It only seemed to be related to the turn signals and brake lights. I don't seem to have any shorts or anything, the charging system is the only part of this car that I haven't had to replace so far (knock on wood). In my opinion, the electrical system on these cars is a definite weak spot. I already rewired my headlights and added relays, and that made one heck of a difference in lighting output.

Kentetsu,

I finally got to drive this project for the first time around the block. It was a blast! Now I want to install a relay like you did. My Carter fuel pump also fluctuates with the turn signal and drops when I touch the brakes.

I appreciate the writeup and the drawing and if you ever get a chance would you please take a picture of the "10 gauge wire attached at the fusible link location (where power goes into the block, not out), with an inline fuse holder "

And the next time you remove the storage bin, I'd also like to see the actual relay and its wiring. That's asking a lot I know but I'm better with pictures.

Thanks again,

DD

i dont mean to disrupt ,but theres no stock fuel pressure regulator, right??

clean85owner

Is the Carter louder than the Holley Blue? I can't imagine how it could be; considering I can hear my Holley Blue OVER my car while travelling at 70mph a lot of the time.

The Holley is HELLA loud, and I'd like to get a Carter if it is a bit quieter.

DublyDurty

Josay721,

There's no stock fuel pressure regulator.



Kentetsu,

Is this the connector you're referring to in the storage bin?



And is this the fusible link block?



Thanks,

DD
