Hi Mark,would like to -but up to my eyeballs in ..........this summer!.

Hi,I will ask the boss .......but I think I already know the answer!

Hi,guess what - it's back- the old hesitation.i think it has to be heat related.It definately doesn't like hot weather and recently it's had a new exhaust -heat source - which runs close to feed/ return pipes as they head fwd to the front of the car just fwd of the pump/filter/accumulator.So I will try wrapping these in heat reflective material and see .On this car the return is tee'd back to the pump and to the tank , could the return fuel be getting too hot at the exhaust and causing problem at the pump.The new pump gets louder in the hot weather just before it hesitates, like its struggling to pull fuel through?

Hi,my system is as attached pic.So if I blank both ends of pipe 17 at the tee's and wrap feed/return pipes near exhaust -hopefully that will solve it! Dave

Hi,removing tees and taking return to tank ,only - has dare I say it -fixed it the pump is now virtually silent! No hesitationThanks to all who posted. Dave
