Title: Pro Hopper Post by: Hydros on January 12, 2013, 03:26:49 PM unknown years
This is one of the best blocks I have seen and may have be introduced in the late 90's early 00's Here is the motor side, note motor pin is at about 12:00 in relation to mounting position Title: Re: Pro Hopper Post by: Hydros on January 12, 2013, 03:33:03 PM pump side
if you note, the block appears to be made to pump out the top port/s. interesting addition of the o-ring on the block. also, note the block has a much larger pressure port. pump head was not checked at this time also note the extra large return port also note the multiple mounting holes Title: Re: Pro Hopper Post by: Hydros on January 12, 2013, 03:37:50 PM This image shows this block was made for pressured tanks, as you can also see the non threaded hole at approx 2:00 just inside of the o-ring.
On top it looks like it says 130 PSI MAX, but may instead be I 30 PSI MAX |
