Yes, the in-tank filter only fitting is half again larger than the in-tank pump fitting and consequently the hose is larger as well. I have replaced the in-tank pump on my '89 and I have replaced the in-tank pump on my GTS with just the filter and new hose. I really cannot tell any difference in performance without the in-tank pump on the GTS, and I have had no vapor lock issues whatever.
