Will stay with the K&B at this stage though......looks really nice in the Playboy.
Foamy fuel you say. I can't say I've ever had the problem. I have made the tanks since the mid '70s, have the flood off line at the very rear and feed line a litle ahead, so if the tank for some reason is low on fuel it should still flood off.
I have used bladders way back.....the best were the good old genuine black pen bladders that seem to be long gone now. I built and lost a couple of Kit's Laser Chaser's in the early '70s, "with KSB shutoff timers, and even a couple of Rossi F1C's, but I just find the hard tank filling so much easier and not as messy.....not that I'm a clean freak. LOL.
To each his own of course.
