From the album: 71 240z
The mechanical pump started to leak due to a cracked diaphragm so I decided to swap in an electric K & N pump. I need to upgrade the coil and wires now though. -
I'm experiencing a slight rich issue and need the groups help. Its an l28et running a JWT 550 kit in a 71 240z. Using the stock l28et fuel rail, Aeromotive FPR with psi gauge, upgraded to bigger fuel line (still using the oem return line), and an unknown in tank pump. Prior owner says its a 300zx turbo pump, but I have yet to drop the tank. I have seen it go to 65 psi with no pressure drop at all. 11.5 AFR until boost crosses the 10 psi mark, then fuel pressure shoots up 5 psi too much (relative to boost )and stays that way. At idle, fuel psi is correct. Cruising, it's correct. The problem shows up only after 10 psi of boost, thats when my AFR's go to 9.5-10.5. Myself and other can't see any smoke from the tail pipe during acceleration. I believe there is an restriction thats not allowing the fuel to return fast enough. Maybe the oem fuel rail? I don't see any pinches in the rail that would cause such a thing. Maybe its my setup. Any ideas where the restriction might be?

I obtained a pre...umm, "hybridized"? '75 280z fairly recently and, having swapped the tranny and done a bunch of other stuff, I'm now trying to tackle a fuel starvation issue. The previous owner installed a very generic Mr. Gasket 12S fuel pump in the engine bay (apparently 4-7 PSI.) This has caused me some fuel starvation and vaporlock issues. The stock mechanical pump on my engine (1970 SBC 350) is apparently not an option, both per the JTR conversion manual, as well as my own experimentation. What have you folks used in the way of fuel pumps? The JTR manual says to mount near the gas tank, but it doesn't mention brand or capacity for an SBC 350...

I am researching the requirements for a fuel system setup that can handle 600whp. I'm looking for a quiet system preferably an in tank setup. Bolt in in better as I would rather spend my time driving than wrenching once its completed. Car will be set up with the stock Aristo 2JZ GTE VVI @ 14 psi initially until a single setup and aftermarket engine control can be purchased and installed. My 4V modular power fox body uses twin in-tank Aeromotive 340 LPH pumps, single #8 feed and a # 6 return to Aeromotive fuel rails, Aeromotive Boost sensitive regulator, and 42 lb injectors. Car makes 525 hp, 505 tq, idles smoothly, drives like stock (until a heavy foot) gets 24 mpg and is very easy to driver; a true street car. You cannot hear the fuel pumps running. Put your foot into it and punished the tires. The car is fun and so much fun to drive, dead reliable and I would like to replicate that in my 71 240 2JZ vvti swap.

Hi, I picked up someone else's headache apparantly, Its running the MSnS and I tried connecting to the 9 port with my laptop (car off), I heard a whistling noise, went to check it out and my fuel pressure went to 0. Next I tried to open up tunerstudio to MSnS, no response. Un connected laptop to MSnS Tried to restart the car and the fuel pumps not working.. Did I fry my megasquirt?

I just put my car back together after my budget restoration. I had removed the fuel tank and painted it. When I reinstalled it, I had some difficulty finding anything to reference where the fuel tank nipples connect to, but I connected the bottom nipple to the outgoing fuel filter. The fuel pump is kicking on, and there is a little gas in the bottom of the filter, but it doesn't seem to be building pressure. I replaced the rubber lines under the car and have them tightly hose-clamped into place. If it matters, my car does not have a charcoal canister under the hood. The metal fuel line that connects to the canister is sitting open. The tank has ~7 gallons in it. Maybe the fuel tank doesn't have enough fuel for the pump to prime? Thoughts?

Hello gents, I am thinking about fuel delivery for my 240z, and I've found this Aeromotive in tank fuel pump: Aeromotive stealth 18688 Here: http://aeromotiveinc.com/2012/11/phantom-fuel-system/ This kit seems pretty good, no needs to baffle the stock fuel tank, outlet, return and vent connections... Does someone here is using this kit? Any comments ?
