Update a year on. This setup is working perfectly even without baffling. I try to keep the fuel level over 1/3rd tank, and avoid hard driving if it’s below. If you’re removing the tank to do similar, I’d suggest just getting an MJ EFI tank that might already have baffling. The tanks / chassis mounts appear the same but I have not compared directly. Cheers
Hayden You’re welcome. This setup is running and driving now. If you are using EFI then no problems. I had to swap over the feed/return lines to get fuel pressure down low enough for the Weber carb. The 6mm return line was restricting fuel flow and creating too much pressure out of the regulator. Not having any tank baffling obviously isn’t ideal, just something to keep in mind if you need to run the fuel level really low. Cheers
Hayden no worries. I will be going EFI in the future as well, this pump is overkill for a blow through carb setup so I’m moving a bunch of fuel around without benefit. However it will be good with the EFI setup, I just didn’t want to re do the tank setup twice. Cheers
Please please do a vehicle show and tell and update I'm currently trying to build on manifold is at the machine shop have installed 15 psi external pump but can't get the malpasi regulator to bring the psi down lower than 9psi (pre turbo) I was thinking my return line wasn't big enough to free flow the fuel back to the tank should I just drop the tank and increase the size of the fuel return as my pump is external ? Or just upgrade the whole tank to the mk tank ?
One day I’ll get around to doing a full video, car is always evolving.. If you can’t drop pressure low far enough, that could mean the return is to restrictive. Could test that by running a hose from the reg return straight into a jerry can, removing any restriction and see what happens. My setup is EFI now and runs 43psi (3Bar) base fuel pressure with a Turbosmart reg
If you have a tray, you will probably be OK. With a tub you’ll need to drop the tank out, but this is just 4 bolts and a few hoses. Make sure car is jacked up high enough to slide the tank out!!
@@Victorsadventures2774 you are a legend, thank you! I have a tub, so that info is great. I have an EFi setup and ran out of fuel at the top end so a better in tank pump like this is the fix I was after!
@@ChadCroft built and fully balanced 4g54, balance shafts removed. ARP head studs and Rod bolts. Dished hyper-eutectic pistons with about 8:1 CR. Currently 190hp/450nm at the wheels with Weber and locked distributor at 20 degrees advanced. 98 pump fuel. I will do a video on the car one day. It will go much better with proper fuel and timing control.

Please show more of this build ?
Awesome setup, will be doing this to my MJ 2wd when I do an efi turbo setup
Thanks! It’s been working fine, and I don’t expect any issues really.
FYI an MK triton 2.4 rwd tank fits into an MJ triton 2.6 rwd. No mods required if vehicle is fitted with a tray
@@michaelfabris645 Awesome, that’s pretty cool info. Do the MK tanks have a baffled pickup? Thanks
Thanks mate, saves me running a surge tank and external pumps

@@Victorsadventures2774 thanks mate. Just in the process of converting my 4g54 to efi and making sure I have everything sorted before I tackle it!

Hi guys, my triton 2.5 has low pressure on fuel system, will the electric pump help?
Please please do a vehicle show and tell and update I'm currently trying to build on manifold is at the machine shop have installed 15 psi external pump but can't get the malpasi regulator to bring the psi down lower than 9psi (pre turbo) I was thinking my return line wasn't big enough to free flow the fuel back to the tank should I just drop the tank and increase the size of the fuel return as my pump is external ?

The one at the ride most side is the floater right?
Yes, tank ports in order from left to right are , Pickup/return lines, filler neck, sending unit/float.
Did you have to take the tray/tub off to remove the tank?
If you have a tray, you will probably be OK. With a tub you’ll need to drop the tank out, but this is just 4 bolts and a few hoses. Make sure car is jacked up high enough to slide the tank out!!

@@ChadCroft no worries!! This is still a blow through carb but is making good power. Also going to EFI soon and have plenty of pump there ready to go.
Are you running the original 4g54 motor?
