Megan Racing Adjustable FPR, anyone know how to install to lower fuel pressure

[300max]

I'm trying to get instructions on how to do this, pictures would be great.

I don't know if the stock regulator needs to be removed or if the adjustable regulator needs to go on the inlet or return side of the fuel lines.

I already have the megan racing unit, and the nismo adapter.

Thanks

goes on the return side, and you have to remove your stock FPR... ill see if i can post pics sometime soon

sorry for the delay, but ill post pics for anyone searching.



note: mine leaked like a bastard, so I replaced it with a nicer unit.

P.S.

turning the adjustment screw IN raises fuel pressure, and turning it OUT lowers it.

So turning it clockwise will make it go up while counterclockwise makes the fuel pressure lower?

[PapaSmurf2k3]

correct. Thats how mine worked anyways. If you think about it, it probably works the same way as a manual boost controller, its got a spring in there, and when you turn the set screw in, it compresses the spring, putting more force on a plate. That plate moves (opens, allowing fuel to flow to the return line) when the force on the fuel side becomes greater than the spring side.

This concludes today's lesson.

which FPR did you end up buying? I was thinking about picking up the MR kit from Enjuku racing. Where did the unit leak from?

I bought the Megan Racing mode plus I bought the Nismo rail adapter from Courtesy Nissan. It works perfectly and appears to be of high quality. The only problem was that I had to take off the the fuel rail to get the stock regulator off. I have a 1995 with ABS and everything near the back of the intake manifold is hard to reach.

I got mine from enjuku. I installed the nismo B adapter while my engine was out. So simple. You have to use one the Z screwdrivers. where one tip has flat while other is phillips. Only way to get there unless you got a ratchet with the tip inserts.

I ended up buying this onehttp://cgi.ebay.com/ebaymotors...%3A11

The other one was leaking fuel out of every possible place it could leak from, the gasket that separates the halves, the fittings for the fuel lines, the fitting for the gauge, everywhere (and this was after teflon tape and thread sealer). Mind you this was an ebay knockoff of the MR one.

you guys need to know that thes 25 dollar ebay crap are junk fuel pressure regulators, just though i would share and say not to buy them. the only way to go is aeromotive.
