Short Belt set-up pics needed please

The only way you are going to get it to work that way is to buy a standard flow water pump. I bought my pump thru jegs for 63.00 The reason for the standard flow pump is because you will now have to run the belt on top of the water pump pulley instead of on the bottom of it. For belt size i'm not exactly sure but i took a string and wrapped it around all of my pulleys and took it to the parts store. Good luck

An easy and accurate way to measure is to use a cloth dressmakers tape, they have inches on one side and mm on the other.

Just wrap around the pulleys like the belt goes and read the numbers where it meets.

Many wives/mothers have those tapes, or they're available at any store that sells fabric, incl Wally World
and they're cheap.
