I was wondering if someone has done a swap with GTE on 99 SC300 or newer?

The temp gauge cluster does not look the same as 93-98 models when you open it from the back to jump the two wires

I have followed the instructions from "swap manual" to have the wire go through resistor, if someone has more suggestions on resistor size please share, otherwise it still reads near the H area

Last thing, 99 models dont have return fuel line so i made one and drilled a custom fittings, but small crack, maybe 1/4 inch is making the entire car smell like a fuel tank, i heard there was a good sealant, anyone know what the name of it was? I tried typical sealents and krazy glues.

Any input will be great, thank you.

P.S. I had this swap done for almost 2 years and my car seems to be running best when i first start the car and having the coolant temp going near the middle, once it reachs norm temp at H, the car "seems" to be running less efficient, it can just be in my head.

your coolant temp should be at middle at all time. when you reach "H" is when the car is overheating. maybe your gauge is way off but if its not, and you keep driving in on "H" you will blow your HG.

as far as the gauges sorry i cant help. 98 and up SC's are retarded anyways...sorry. just so different from all the other years.

to seal up the fuel rail id say take it off and try some JB weld. the best way to would be to remove the fuel rail, wash it to ge fuel out, and braze it shut.

To clearfy what I mean by the coolant temp. is that when you do the swap, it will read H, even though the temp is at normal operating. It's just a glitch in the swap process, as far as doing my research.

The fuel smell is coming from fuel return line, since 99+ do not have a fuel return line i had to make a custom AN fitting and doing so left a small leakage area in the rubber sealant.

Thanks for the reply though

Thanks for info! Your project looks great! I have a similar set up with BL Tranny and BL 67DBB, I really should consider taking my fuel tank and replacing it with 92-96 fuel tank.
