Default Re: Vapor Lock 101 ?

Marc:

I have a 53' Mercury and had the same proublems. I finaly gave up and put a new Carter fuel pump on the car (from MAC's). I mounted it on the frame of the car just in front of the rear wheel.The nice think about the new Carters is that they are set for between 3.5 and 4.5 lbs, so you do not need a fuel regulator. I did put a new mech fuel pump on the car too. When I begin to have proublems, I simply hit the switch for the pump and once the car picks back up, I turn off the switch and continue on with the mech pump. I did a bypass hose around the pump with a check valve from Graingers (they have a store in Denver). The check valve is a perfect fit and cheep.Yes it is not the cleanest instalation (too many hose clamps) but it works great.

Good luck.....
