Fuel pump
« on: March 30, 2012, 10:16:53 AM »
Would like to clean up my motor . Get rid of the stock fuel pump . Electric looks cleaner . The old pump is still good and has lasted since 1994 . Will I get the same out of a electric ? Pros & Cons . 1776 2x 40 dells 110 .

they only thing i'v heard is the psi output is all over the place, so you'll probably need a fuel pressure reg. like this one just find the psi you need they come in different psi settings.

If you are going electric, definately put a fuel pressure regulator inline. This Holley unit that Buddy Boy linked is a great choice.

I'm opposed to pressure regulators.  It's another part to go bad and leave you stranded on the side of the road.  At night.  In the middle of nowhere.  Out of cell range.  When it's raining.

A pressure reg is what you need when you have a pump that puts out the wrong pressure.  My choice is to buy a pump that delivers the correct pressure in the first place.  That's what I did 12 years ago.

I believe the CB rotary pump delivers the right pressure, so no regulator needed.

Here's the CB pump, print and take a pic to your local FLAPS as Carter and many others make (or resell) the same unit, often a few bucks more but no shipping and a warranty close to home. Just make sure it's mounted below the tank as it can't draw fuel when dry, a relay from a Rabbit is a nice feature for safety as well.

that cb pump looks identical and performs identical to the carter i had to put in my caprice when i carb on a fuel injected block. i think lordno charged me about the same $ too. the year warranty was reassuring though

Rather than start a similar thread, thought I'd ask here if the Carter PN:  GP60504 with 4 psi is suitable?

Hey Niel, that's exactly the pump to get.  There are cheap Chinese copies out there, but that is the real deal. it's actually about 3.5 PSI not 4 PSI.

Don't forget to increase the tank outlet fitting size as well.

Cheers.

I got mine from CB Performance and finally got it installed and running. So far so good. A lot quieter that the facet pump I had in there.

Very nice installation!

A couple questions, as I'm proceeding with the same Carter fuel pump install.  Did you wire to the fuse box (for power) to work with the key?  What relay, or other safety system, did you use to stop the pump in case of an accident, etc?  I see a Rabbit relay mentioned above, but I'm not sure of part# or alternatives.

This would be for a 12V '68 Beetle.

Thanks!

I already had an electric pump before hand and I cant remember the part number of the relay I used, I did it back in 1998 when I originaly built the car, but it was a factory VW 5 pin fuel pump relay that required a tack signal to turn on and shut off with out one. Dave used the same ones for his rally Beetle. Give him a PM as its probably still fresh in his mind.

the cb one just has hose clamp ends on it, by the looks of it
you have AN fitting's on yours do you remember if they just unscewed and you screwed in the different ends?

I use a relay out of a CIS VW/Audi. Rabbit, Audi 4000, Audi 80/90, etc. The relay will cost you about $30, but the fuel pump only runs when the engine is running. Thus in an accident/etc you aren't pumping fuel onto the fire.



Terminal 30 gets power from a circuit which is always hot; Battery +.
Terminal 15 gets power from a circuit which is hot with the ignition switched on.
Terminal 31b receives a tach signal from the coil to indicate the engine is turning.
Terminal 31 is chassis ground.
Terminal 87 provides +12V to the pump.

Thats the same relay I used. Thanks Dave.
Russ, those arent AN fittings on the ends of the pump itself, just hose clamped on the line and a wanna be AN cover to make it look purddy. The pump has its ends built in so nothing unsrews. I thought about cutting off the flare on the end of the pump lines and using compression fittings to be able to use ANs but got lazy and decided not to.
Ive been driving the car all this week and it is sure nice not to have to listen to the rrraaaatttt of the old Facet electric pump I had in it before. Definately an upgrade.

I finally installed my Carter fuel pump yesterday and went racing at Castrol Raceway in Edmonton last night.  The Beetle ran 3/10th's  of a second faster, as I was able to get some 13.1 and 13.0 ET's.  I still have the stock fuel lines for now...one change at a time.

Jordan: thank you for the photographs...I ended up copying your setup for the most part, except I put the fuel filter inside the brake line bracket, but used the same U-turn fuel line.

Because I was short on time, I just wired the power to fuse #2 for now (10-fuse '68 fusebox), but would like to add a relay to stop the pump in the event of an accident.  I have one of these relays...it has a slightly different part number to the one shown above, it says:  3.300.100.  Here's a couple of photos:




It's a Kaehler part which I believe might be for a Rabbit or Audi.  It's got a 15 amp fuse on top, which appears to be the only difference to the 3.300.300.  Anyone use this 3.300.100 before?

thanks!!

Yup. Same wiring diagram. My brain is drawing a blank as to why the fuse is there, but there were diagnostic tests you could do with it. Regardless, should work fine.
