These Lasers had really crappy fuel pumps off the lot, so an upgraded pump is about the only nonstock part on it. I'm only shooting for around 12psi, which it should take easy.
These 2.2s will handle 25psi with few issues according to the Internet.
Coincidentally, the guy I bought this Laser from blew up the KA in his Silvia last night.
