we do make a 1in Modular Hose version - but it's hard to say if it will fit your specific over-to-back return pipe.Ya it would be super easy. I actually have a short piece of 1" vinyl from pump to return
I would love to try one of the 1" RFGs but my 1" return is over the back and I don't think they make 1" loc line sections unless I'm mistaken...

the 1in Modular hose fitting that we sourced out (and that this RFG fits) has an outer diameter on the ball side of 1.25" (~32.95mm) . if you can provide the brand of pipe you have or a measurement of the ball-side, we may bee able to figure out if it will fit.
