Fuel pressure shows 62 psi key on. going down the road level pavement drops no further than 55 psi heavy acceleration going up a long hill pressure drops to 42 psi engine will back fire and surge. when you back off to normal acceleration fuel pressure returns to 62 psi. filter has been changed and it made no difference. this 8.1 is in a 2008 Gulf stream Sun Voyager motorhome, with 34100 miles on it. does this appear to be a fuel pump problem?
Thank you

A drop in fuel pressure like that under load would suggest that the fuel pump is having a hard time keeping up with the demand. Replacement of the fuel pump will likely cure the problem.
I need a fuel pump and any related part's to drop tank and clean out for new pump.I need parts # if possible to all. Thank you James Hutcheson

This would be the correct fuel pump. For any additional parts or help just give us a call and we can determine if anything else might be needed.
The motorhome will not start and the fuel gauge is pegged at E with a information center message " low Fuel" The generator runs and it will not draw gas out of the tank if it at or below 1/4 full, so the tank is at least 1/4 full. Is This the correct fuel pump for the above mentioned motorhome and does it include the sending unit and pressure regulator?

Yes, the W0013952 is 100% the correct fuel pump for your VIN.
Does this pump have a check valve. My rv will crank for several secounds like it has lost its prime. Just started a couple of weeks ago?

Yes this pump does have an integrated check valve. Does this occur all the time or only on a restart from sitting for a short period? If you cycle the key on and off a couple times and then try to crank does it fire up or still crank for several seconds?
