I was going to get a electric fuel pump for my 68 beetle with 1916, most likely this one http://cgi.ebay.com.au/12-Volt-SOLID-STATE-ELECTRIC-FUEL-PUMP-4-5to6PSI-129LPH_W0QQitemZ350217911777QQcmdZViewItemQQptZAU_Car_Parts_Accessories?hash=item518a9d3de1&_trksid=p3286.c0.m14&_trkparms=65%3A1|66%3A2|39%3A1|240%3A1318|301%3A0|293%3A1|294%3A50

Is there a particular spot i should or should not put it?
Cheers.

Under the fuel tank. Make sure you wire it so it auto cuts if the engine stops, also make sure you check you entire fuel system, lines fitings etc while you at it.

Check whether it is a push or suction pump as this also makes a difference to location,but I agree with both of the other replies.

Quick question.. but how does this soild state pump work?? Solid state means it has no moving parts right? so how the hell does it work :P

Not sure but my friend put one in his Kombi and all is good. This might be a silly ? but do you block the old pump off or take it out or anything?

be carefull if the bakelite flange is tight in the case

they can snap off in the case real easy and its a real PITA to get the remains out

You can place it anywhere... front or back...
I placed Mine under the fuel tank on the front wall
I have a switch under the dash that I can turn it off with..
its hooked thru the ignition, so the key has to be on for power to the switch and then to the pump..

cheers

they are a good pump and I have used the same style for over a decade with no problems.

The pump needs to be mounted under the tank and should also be mounted at 45deg...............so that the fuel enters from the bottom and exits out the top....hope that makes sense !

So i should get an auto electrician to hook it up through the ignition then i guess along with the horn. I think i get what you mean with the 45deg too Craig.

best to wire it up with a saftey cut out
so if ur in a prang and the engine stalls the fuel pump doesnt keep running

i did this first time by using the charge light from the alt to switch a relay
as long as the alternator was spinning the fuel pump ran

but i found a better method
fuel pump relay from an 80s EFI car works well
just takes the tach signal from the coil

There is an of the shelf relay that is used for LPG setups. It also primes the system when you switch on the ignition. Ie it runs the pumpf ro about 3 secs.

I don't know either....
All the electric fuel pumps I've seen tick when they are pumping....
its strange that an old looking design, metal pump should be labelled as solid state...

Guessing....
Your mechanical pump is using a push rod to move a diaphram that pumps the fuel.
These ones use magnets that are establshed by passing a current though a coil of wires.
By changing the poles your able to make a metallised diaphram bounce back and forth ( just like the push rod does on the old style pump but now you use the magic of a magnet).
Thats why these things are metal!
They say no moving parts burt really there is no rotating parts. the diaphragm is still pumping.

Craig, why 45 degrees?- Should not matter.

BiX , Where do I find these relays?

Most electric fuel pumps are not in the engine bay, probably because they don't like the heat or they are push pumps.

I'd fit it under the tank and definitely fit a cut off system linked to the generator output.

If you link it to the generator output, it will cut the fuel if the engine stops and the ignition stays on.

That also means that the pump won't pump until the engine is cranking over when starting.

That should not be a problem. To need to crank the engine a bit before a start is better than an instant start, as it gets the oil pressure up a bit before the engine starts.

That's why engines that start instantly usually clatter until the oil pressure gets up.

Some years ago I needed an electric pump to get me back to the city when the mechanical pump on my Hillman Hunter failed. It was clearly marked as not to be fitted anywhere near the battery. Why? I don't know. Maybe sparks?

What you probably need is a low pressure Facet pump.

As to the old pump, take the push rod out, re-fit it and blank off the fuel holes.

been there and tried that one, works well cept the fuel pump wont run when cranking, you need to wire in a primer button

the genny doesnt spin fast enough when cranking for the charge light to pull a relay in

Hi

I went to my FLAPS today and asked them to get me in tachometric relay, they tried all their suppliers, nobody had heard of them.

Joel, do you have a part number for the VL relay?

You can get the tachometric relays direct from CBB 02 4722 9313

yep, will grab it for you next time i'm down there

its not the sort of thing a flaps would carry, you would need to order one through a dealership spare parts department.
dont trust a second hand one

early EFI water cooled vws use a similar relay

Thanks Joel

Holley make a relay that works on oil pressure.

Matt, I already have a pump, I will call to see if I can buy the relay.

That system looks like it just uses a fuel tap type shut off, you need something that will actually shut the fuel pump off in my opinion.
