how much they go for?
And whats the diff between #6 and #8?
They are expensive because they don't make them anymore.. but you can get them for 120-180... Just make sure what your getting is a real FENNER... it will look like the one in my first picture... Some places sell cheap copies of these pump heads..
#6 has smaller gears it's a high pressure unit.. they are ported for more flow with a slight decrease of pressure... pressure is everything when hopping...
The #8 has larger gears is also high pressure but because of the the porting and large gears it movers more oil... better flow. The #8 can't handle as much abuse where the #6 is almost bulletproof...
but no pump head is perfect...
