noisy electric fuel pump

[ez73]

my mechanical fuel pump on my 73 quit working and because of diffulty removing with the ac bracket and could not find a pump in stock of good quality, I put on an electric fuel pump. Ilooked all over town for a low psi (4.5lbs) type. purched a Facet box style pump. Installed it back at the tank where the original assist electric pump went (long dead) used the same mounting plate and was able to trace the electical wires to the relays and jumper them. My question is ,this type of pump clicks all the time and is kind of annoying. On the newer cars with pump in tank you only hear it pressureing up and never hear it again. During my search I ran across a Holley hi psi pump (14psi) with a pressure regulator ,looks like a good pump I would have needed a pressure guage to set it,and did not come with any soft hose fitting. Wondering if this is the same type of operateing system Anybody have any answers on this? d***

Get a Holley Red top. Max 7 PSI and a rotary type.

I've heard people using a Mazda RX-7 electric fuel pump. Not sure what year though. You should be able to find out by doing a search.

I went to the club archives after this post. Two types of pumps pulse and gear (rotary?) my Facet is pulse. Holley blue top is not pulse (14psi/presure reg.) The old archives said holley red top is noisy, one guy recommends Mallory. I just bought the Facet yesterday ,the company didnt think the mfg. would take back with nothing wrong only noisy. Going to detach mtng. bolts and let hang for a test to see if this reduces noise. If so come up with some kind of hose mount. d***

d***, I have a mechanical fuel pump if you're interested. It's brand new in that it's never been installed on a car but I've had it laying around amongst my parts for so long I don't even remember where I got it from. It was made by Kyosan Denki Co., Ltd. It's in the box still wrapped in plastic and has three gaskets and a little info sheet printed in Japaneese and English. It is, however for a four cyl. The box says 'NISSAN BLUE BIRD 510 BLUE BIRD NEW" and it's part number is NP-456. Is there a difference between the 4 cyl and the 6 cyl fuel pump? If this is something you can use let me know.

Well, I just looked at the microfiche and a Z pump is different. Oh, well, I tried!

Thanks for the thought Stephen looking at the gaskets knew it would not work z car has 3 hole gasket d***

I wonder if it would be worth anything to the 510/Bluebird crowd?
