TRD's check valve solution works like a charm, I installed the primer pump/check valve and an Ofna fuel filter while I was at it, and it made a world of difference.. My engine temps hardly vary at all, maybe 10F or so.. As for mounting it you may have to get creative, I screwed mine into the side of the chassis using one of the transmission screws right next to the handle, seems like the best place.

I have a cousin who is local to me who owns a T-Maxx, I've yet to run my GST up against him because he keeps blowing it up before I get a chance to, last I heard he cut his antenna and didn't test the range, 10ft later it was cruisin oh at around FULL throttle directly for the nearest curb.. One month and an entirely new front end later he's almost ready to run it, I'll be sure to let you guys know how it turns out.....
