I just replaced my OPS, fuel pump, relay and added a Leroy Diesel Fuel pump relay To my 96 Suburban and my 20A fuse keeps blowing any low speeds under load 90% of the time. I went 3miles up a winding mountain at a speed of 25 to 35 mph and blew that fuse 23 times! Good thing I had a bunch of fuses going up to 30A!!! Also this morning I blew the fuse putting it in reverse and idling backwards, wen I replaced it I used the peddle a bit AKA 1500-2000 RPM and she went fine. Think there is another issue...... thinking it could be Transmition or what ever that fuse goes to..... just a SWAG...... this is driving me nuts!!!!!!! Anyone have any help that could be thrown my way along with some luck

Oh when the fuse pops oil pressure is in the 30 to 50 PSI range and i was driving from FL to WV and the only time they popped is when I was pulling of the highway to get fuel and when I was going up the mountain going around curves at around 15-35 MPH
