To be honest I am not sure I buy that. Plenty of folks using hot 3.6 engines with the stock fittings.
Interesting, I'll check my rubber lines again. It happened once before a kink started to develop on the rubber line from tank to pump. Could be a partial kink?
Isn't the 911 tank supply line fitting from strainer 10mm? You'd think there'd be a reason it'd be size matched to the CIS pump.
If I'm incorrect, I'll apologize for asking the question and wasting forum thread space.
With Ben
1/4” is 1mm bigger than 5mm
1/4” tube will flow about 30 gallons per hour at 30’ length
A 914 is much shorter than 30’ (both ways) and there is no way a 2.7l is consuming 30 GPH of fuel at normal road speeds.
I don’t have parts in front of me to measure but thought supply line was more like 8mm and the return was the smaller (5mm) line?
Partially plugged sock strainer in the tank as other potential issue? Dirty - constricted fuel filter? Pump and/or regulator going south? Improperly rated fuel hose on the suction side of the pump collapsing? Fuel tank vented properly? CIS fuel distributor in need of rebuild? Sticking or binding of CIS air sensor plate / balance beam?
Lots of other more plausible suspects for starvation at high RPM.
