rcraft Posted June 24, 2011 Share Posted June 24, 2011 Here's one that is puzzling me. When my '64 Riv is parked in my drive slightly uphill, it is hard to start, as in not getting fuel but cranks well.When I park it headed downhill, it fires right off.Is fuel draining away from the fuel pump and I need a new one? Or is there/should there be a check-valve in the fuel line?Any ideas? Ray Link to comment Share on other sites More sharing options...

rcraft Posted June 24, 2011 Author Share Posted June 24, 2011 Not very - maybe 10 degrees. Link to comment Share on other sites More sharing options...
Jim Cannon Posted June 25, 2011 Share Posted June 25, 2011 The check valve is built into the fuel pump. If you are not sure how old the fuel pump is, that might be worth changing. I suspect the ethanol in our gas today is messing with the rubber in the fuel pump.I have heard of guys putting a small electric fuel pump right where the steel lines end and the rubber fuel hose begins (up to the fuel pump, under the passenger door). You hit that fuel pump switch for a minute before you crank and that puts fuel all back up in the carb. Link to comment Share on other sites More sharing options...
rcraft Posted June 25, 2011 Author Share Posted June 25, 2011 Thanks again Jim. I believe I will try a new fuel pump. Not that expensive anyway. Ray Link to comment Share on other sites More sharing options...
1965rivgs Posted June 25, 2011 Share Posted June 25, 2011 Troubleshoot your problem by clamping off the rubber line then try starting after sitting overnight. If you suspect the fuel is siphoning away the clamp will not allow this to happen and will keep fuel available for starting. Tom Mooney Link to comment Share on other sites More sharing options...
