Electric Fuel Pump Location?

[david premo]

So the pump that I installed on my car is the Nissan 73 240Z electric pump that is internally regulated to 3.5 PSI and is extremely reliable and quite. The 73 240Z and 74 260Z used these pumps to prevent vapor lock issues because of the high under hood temperatures from the emissions equipment installed in those models. The pumps are pretty hard to find now and I recommend to people that are looking for a high quality inexpensive pump to buy a Facet Gold-Flow that is regulated to 4-2.75 PSI. They are OE on many European cars and trucks and are also used for airplanes and watercraft.

Gold-flow, that includes the Red Top, right? With my triple solexes (on the 240Z) I use a regulator, as it pushed out far more pressure than I wanted.

When you go in their catalog it specifies the pressure range of each unit by model number, you need to check the pressure of the specific unit you are looking to order. The Gold-Flow part number 477060E unit has a 4-2.75 PSI delivery pressure at 34 gallons per hour and is a 12 volt unit. So you really need to review their catalog specs to make sure that you are ordering the correct unit for the application. The Gold-Flow series has a PSI range that is as low as 2.5 PSI and as high as 8 PSI depending upon the part number you choose. Also the GPH gallons per hour changes as the pressure increases the volume decreases. The one I recommend to people delivers 34 GPH and typically stays around 3 PSI under flow and then locks up at 4 PSI under low or no demand. I hope that helps.

The Carter P60504 rotary inline is quiet, and internally regulated at 3.5 psi. Works well supplying the Mikuni-Solex 44PHH-2s.

Information about this pump, found on this link, also says "24 inch vertical dry lift."

So, I'm assuming it doesn't require mounting near the tank, and is not necessarily spec'd as a "pusher" type pump....would that be so ?

[david premo]

No it really does need to be back near the tank, only diaphragm electric fuel pumps are any good at pulling fuel.

Woo Hoo !
This was kind of a hassle, but I wanted to see if I could do it..., I had the original post of this topic from 2009 saved as a PDF file. I frequently bookmark topics / threads that interest me, and create PDF files from them. I couldn't directly extract the pics from the PDF files to this post, so I took pics of the images on my laptop with my phone, and then cropped, and re-sized them, and re-inserted them into the their proper places, beneath their captions, where they were missing. I hope this helps...

In the first picture you can see the mounted pump on the trunk wall above the gas tank mounting area. This is also the same spot I've seen three cars use bolts and nuts drilled thru to trunk for mounting. I welded a mount in place.

This is where the weld burns show in the trunk.

This is another mount for a larger racing pump
I was going to use. It is directly opposite on the
package tray wall.

Thanks, Dave !

Does it have a S bend about a foot out of the tank my 70 did its 1/8 " ID at best in the bends then they calcium up
I removed mine and flow was good
You should have a 180 ° line loop that goes up on the rear back ,it's to stop siphoning of the tank like in a wreck and a line is cut

Mike, thanks for the photos. So, ideally the pump input should be lower than… the bottom of the long pickup? Or just the supply/output higher on the fuel tank? I guess it’s ok that the fuel hose goes up to the roof before it turns down to the fuel pump?
