Post by: hairyhoover on December 22, 2007, 02:16:41 PM
Hi, ive just look my fuel pump out of my fd hoping it would be nice and easy to identify... but its not.

Looks bigger than the stock one mate, standard one isn\'t held with jubilee clips! Could be a gtr pump?

Your pump has a built in regulator you either have an apexi or tomei pump for the nissan skyline. Very good pumps unless you exceed the recommended pressure.

Yeah that\'s the one the Tomei looks exactly the same but comes in a box that says tomei instead of apexi. Don\'t think there is a difference at all.
The built in regualtor is to protect the pump so it will cut fuel if it see\'s more than 75psi of fuel pressure. To get to that kind of pressure you would need 50psi base pressure and would need to be running 25psi of boost, so nothing for you to be concerned about.

Ha, nice one Darren.  That is the same pump I have, although mine is slightly modified.

Excellent bit of news !!

edit: you might want to consider a swirl pot though, in addition to an fpr

Hmm. What noise is it supposed to make when it\'s priming?

I couldn\'t hear my standard pump at all. Untill I put a uprated one in, when I turn the ignition on (pump primes system up to pressure) I hear a momentary wurr.  So at least, in my case, yes this is true :)

I don\'t know about in an fd but in other striped out cars you can hear a the pump prime. Also can hear an uprated pump constantly wurring.

that sound about right, just a slight wuurr.
 
may be some one else that has a standard FD could also confirm this??

Ive got a skyline R33 GTR pump and it looks exactly the same, I had to modify the pick up sock from the old pump tho for it to fit

noisy old thing but holds pressure well
