Hi Kris,

I just ran a stock pump from 20 years old and it ran very well.
Bud you will go on E85 is it ?
I am not sure about that because i have no experience with that.
Have you contacted Carl yet ?

Marcel.

Quote from: JayDee;820914So you have 600+ or have seen this nice round number achieved? Here are the flow rates for a standard pump that I found on the net.
FD Pump @ 12V

PSI GPH LPH
40 52 197
45 50 188
50 47 178
55 45 171
60 43 161
65 40 151
70 35 132
75 30 115

With simple mathematics you can work out if it will come close to being able to flow enough fuel.
Why would you keep a 20 year old pump in your car if modify it? So if buying a new pump why not get a higher flow one rather than pay for a new stock one?
Also a lot of cars that I see that quote such high figures are no where near the quoted power, unless there talking about my little pony horse power....

Nice countwork.
Are you a stockholder for bosch 044 ? (lol).
Ask Carl from Hayward rotary he will verify this.

not yet, first finish my rebuild ;-)

How are you gonna go with ports ?
And what size of injectors do you have ?

Stock holder for Bosch?? I do not see anywhere where I mention Bosch??
So you are quoting information that you have no idea if possible.
See how far you get on e85 with a stock pump, I dare say you will run out of pump just at high rev\'s in vacuum from what I\'ve seen in the past and that\'s not due to the pump....

I have no need of verification.

looks like you should do some research

i suggest you ask carl who jaydee is and he will verify lol:Laugh:Laugh

Mate, if I am not mistaken, Jaydee is the guy who mapped and tuned that 8.81 second quater mile fd isn\'t?

Really helpful thread, thanks.

Could i confirm, with the earth wire at the connector, in your diagram it looks as if you have spliced to the original earth, but you mention, cut and new earth run to chassis. Do i need to splice a new earth or can i just run to chassis from the connector end?

Also, does the original relay need to put in place or simply bridge out the two terminals?

Thanks

Hi mate,

Yes just cut the wire at the connector and then connect a thicker gauge cable to this and run it to the body as a new earth. Problem with the existing is the 16 gauge cable is too long and too thin to cope with the 044 and will heat up due to the amperage. Mines been running over 3 years no problems like this.

Yes keep the original fuel pump relay in. This ensure it acts like stock setup i.e. priming for 5 seconds and not running when engine off. All thats happening is instead of having the fuel pump as a load on it, it has your new relay to feed your 044. It keeps things simple rather than having a new manual switch or connecting into other circuits.... Just connect a jumper wire as shown to disable the speed relay circuit. This ensures your new relay always sees the full 12V switching circuit.

Hope this helps

Great help, apart from the questions above, really easy to follow. Bought a one way valve from ebay on recommendation too.
Thanks again.

P.s How do you get the standard relay back in if you have bridged the those connectors with spades?
