Posted December 8, 20213 yr comment_632871 Hi. I have a '72 240Z with a Rebello engine, TWM EFI/etc, and a '76 fuel tank plus an old, used '76 fuel pump. The fuel pump is quite functional but noisy so I wish to replace it with a quieter and perhaps more efficient model. Any ideas?

December 8, 20213 yr comment_632878 If you can get OEM noise might be coming from a restriction in the line or in the filter I would check that first Link to comment https://www.classiczcars.com/forums/topic/66130-optimal-replacement-fuel-pump-for-76-setup/#findComment-632878 Share on other sites More sharing options...
December 8, 20213 yr comment_632891 I used the Airtex E8312 pump, and got about 40,000 miles out of it. It's quiet is you mount it correctly. If you want to spend a little more you can try a different brand. Ford used a high pressure external pump for their late 80's models. Looks like it comes with a mounting system that keeps things quiet. Check the mounting on the pump you have. You want the pump to be resting in a bed of rubber, no metal to metal contact with the body. https://www.rockauto.com/en/catalog/ford,1988,f-150,5.0l+302cid+v8,1121780,fuel+&+air,fuel+pump,6256 https://www.rockauto.com/en/moreinfo.php?pk=383109&cc=1121780&pt=6256&jsn=986 https://www.amazon.com/Airtex-E8312-Electric-Fuel-Pump/dp/B000DT7Y7K/ref=sr_1_4?keywords=e8312&qid=1638982867&s=automotive&sr=1-4 Link to comment https://www.classiczcars.com/forums/topic/66130-optimal-replacement-fuel-pump-for-76-setup/#findComment-632891 Share on other sites More sharing options...
December 8, 20213 yr comment_632894 Forgot to say the factory pump is only about 30 GPH. Many people get the Walbro high volume pump and experience noise because it pumps way more fuel than the engine needs or the lines can handle. The 240Z is known for having a small return line also which sometimes makes fuel pressure hard to regulate. Here's a calculator to get you close. That Motorcraft pump is used on their smaller 4.9 liter engine also. The Delphi and Bosch pumps are worth considering too. https://raceworks.com.au/calculators/fuel-pump-calculator/ http://www.kylesconverter.com/flow/liters-per-hour-to-gallons-(us-fluid)-per-hour https://www.rockauto.com/en/catalog/ford,1988,f-150,4.9l+300cid+l6,1121779,fuel+&+air,fuel+pump,6256 https://www.rockauto.com/en/moreinfo.php?pk=383109&cc=1121779&pt=6256&jsn=1074 Link to comment https://www.classiczcars.com/forums/topic/66130-optimal-replacement-fuel-pump-for-76-setup/#findComment-632894 Share on other sites More sharing options...

December 8, 20213 yr comment_632900 I picked Ford just for fun but there's a selection of 280Z pumps also. The Ford pumps have special nipples. Probably the same pump as the Nissan pump. https://www.rockauto.com/en/catalog/nissan,1976,280z,2.8l+l6,1209226,fuel+&+air,fuel+pump,6256 Ford - https://www.rockauto.com/en/moreinfo.php?pk=1111648&cc=1121779&pt=6256&jsn=32 280Z - https://www.rockauto.com/en/moreinfo.php?pk=1112295&jsn=267 Link to comment https://www.classiczcars.com/forums/topic/66130-optimal-replacement-fuel-pump-for-76-setup/#findComment-632900 Share on other sites More sharing options...
January 12, 20223 yr Author comment_634118 Thank you Zed Head for the thoughtful replies and details. The car is in storage for the winter so I will tackle this after things warm up next Spring.

August 2, 20222 yr Author comment_643221 For the record, I just replaced my old stock fuel pump with a brand new one — Nissan OE for 76 280Z and also beefed up the noise/vibration suppression. The results are simply amazing. The new pump is virtually silent. The old pump functioned normally but must’ve been on its last legs. Thanks for the tips.
