If you have used the Tanks Inc fuel injection tank for your EFI installation, how/where did you route your tank vent line? I have no charcoal canister. Thanks.
I was just reading a thread from Richard454, he used an inline charcoal filter and routed it to a marine style vent mounted where the radio antenna had been.
Thanks Kris, that is what I was thinking. There really isn't any place higher than that.
I have a FItech system and am installing a Tanks Inc EFI tank now to get rid of the noisy pump that came with the FItech. I don't have a canister and had installed a vented cap which has worked fine. Do you think I still need to use the vent and VVR that came with the Tanks EFI tank? I am concerned about vapor build up in the top of the area where the tank is near the antenna.
Someone suggested routing the vent line up high as mentioned and then turn down to a point below the tank level. It will allow venting and should prevent draining in the event of a rollover. If you use a vented cap it will allow air in freely and has a overpressure valve that opens at 1-2 psi(?). Personally I will have mine open so it breaths freely in both directions.
HI stingraymax, what every came of your EFI conversion on your 75? My fuel pump seems to be gone out on my 76 and I'm wanting to convert to EFI but I really would like to have an EFI tank.
Unless you got a rusted out tank, you don't need a new tank, check the black plastic float valve on the top/driver side of the tank it's a float ball that shuts off fuel when cornering to the right, with a full enough tank, the line than goes to the charcoal canister, then it goes to PORTED vacuum, which is before the throttle blades and supplies minor vacuum to the line, enough to keep fumes outta your garage, I have that stock setup with a vented/locking cap and no sweat....
the FI pump is mounted on the rear frame rail, feeding the stock 3/8 steel line, the stock 5/16 line returns to the top right/pass side of the tank....from the pressure regulator....my pump is a Walbro pump that can be mounted dry like mine or stuck in the tank of you like extra work that serves no purpose....
Thanks. Problem is that I believe the bladder in my current tank is collapsed so I want to change it anyway. The reason I'm thinking it's may be collapsed is when the gas gauge shows empty, I can only put about 9 gallons of fuel in the tank. The gauge then shows full so something is up between the tank, gauge and sending unit. The GM manual says the tank is supposed to hold much more than 9 gallons.
Not to rain on anyone's parade but the internal 255 pump supplied with the Tank's Inc EFI tank is not exactly quiet. I used a Tanks Inc efi tank on my 68 C10 LS1 swap. You can't hear it when you are driving but it's easily heard when you are standing next to the truck. On past LS swaps I used Bosch 044 external pumps. They seemed to much quieter than the 255 pump.
The WalBro pumps everyone uses for their in-tank pumps can be anywhere from almost dead quiet to annoyingly loud. What I've found is that they usually start out quiet but if they ever have any restriction on their intake (like a partially clogged filter sock) they get loud and will stay loud even if the sock is replaced. I also found the more aggressive injector/fuel system cleaners will damage them and make them whine. Oddly enough they keep working fine even when they whine. Never had one fail on me. They just get loud enough I can't stand it anymore and I replace them.
Now that you say that I have 98 Wrangler with a LS1/4L60E combo. Did it about 10 years ago. Replaced the stock Jeep pump with a 255 pump. Its almost dead quiet. It has the stock 255 pump sock on the end of the pump. It has been rock solid reliable.
Having said that the Tank's Inc is a good piece. Well baffled on the inside. I had to play with the fuel level arm a little bit to get it to read correctly.
Hi all, I'm still trying to figure out which way to go with the EFI conversion for my 76. I ran across this RobbMc powesurge. I'm just wondering if anyone here has used it and has any take on going this route for my conversion. Thanks.
I'm using the Tanks Inc kit, which included the new powder coated tank, pump, and sender with all the necessary hardware included, it's an all inclusive complete kit. As Zwede stated they are not absolutely quite, mine makes noise before the engine is started but after it's running the sound isn't heard due to engine noise. I used the fuel regulator offered by Tanks Inc to eliminate the need for a return line from the ECU. T
This is the modification done to the intake manifold.
