Hey all,
I had a shop do a cali legal swap on my fj60 and am having issues with the fuel tank. Could really use some collective mud help to get this thing back on the road as the shop took over 2 years to get it back.
it's got the carb referee sticker but have had some issues since i got it back a major one being the fuel tank leaks fuel when filled up.
Some context, it's an 83 fj60 with a 5.3 vortec running an external inline fuel pump.
I've pulled the tank and here's a wide picture
issue # 1
The shop used some kind of epoxy to fab a plate for the fuel tank pressure sensor and the fuel level sensor, both needed for the evap system.
The epoxy has cracked and leaks when filled up. I'm not happy with this epoxy solution and was wondering how other cali smog legal swaps handled the fuel tank pressure sensor( black plug)and the fuel level sensor.( white plug)
#2), the gm fuel level sender has been grafted onto the factory one. I believe the gm one needs to be setup like this so that the ecu knows when to and when not to run the evap system. the down side to this is that its hooked upto my speed hut gauges, but the signal is very inaccurate. it'll be full for most of the time then drop rapidly when its nearing an empty tank.
Seems like some people use this unit
, and it works great with the speed hut gauges,
i'd also like to use this unit to get a more accurate reading on my speed hut gauges but need to make sure the gm ecu is getting a right reading on the fuel levels for the evap system.
I was wondering if i could tap the gm fuel level sender wires into the tanks inc fuel sending unit and if i did would the gm ecu get an accurate reading? i'm not so tech saavy with ohms and resistance etc, but guess what i'm asking is, does the floatless fuel sending unit and the Gm system speak the same language?
Would love any other tips or advice, on the fuel tank setup for a cali smog legal swap.
lastly, the shop buggered the mating surface where the gasket for the fuel level sender sits on. this really pisses me off. i'm also thinking it's causing leaks, do you guys have any thoughts on how to repair this?
hope this all makes sense and would really appreciate any input from anyone.
thanks again
Kevin
