The mechanical fuel pump on my 1098 Van had been playing up and finally needed to be replaced. I purchased a new aftermarket fuel pump and spacer and after a few hours of swearing I was able to get the old one off.
The new spacer was twice as thick as the current one so I looked on the forum and the advice seemed to be make sure the spacer size stays the same. I measured the reach of the lift arm on the new and old pumps and they were identical so ground down the new spacer leaving it slightly thicker than the old one which wasn’t going to suit the new pump as shown.
I put the new pump on cranked it over and was delighted when it started as the pump must have been working. Soon after I had fuel streaming from the overflow in the float bowl, I checked the float and needle and all looks ok plus I had never had a leaking issue prior.
I think I should have left the spacer much thicker as the old spacer may have been thinned down to pump more fuel with an old dodgy pump?? Now I think the new pump if pumping too much.
Am I best to get a new spacer and start again? Or put a fuel flow regulator in the line, the problem I see is too much pressure on the hoses and pump as fuel was pouring out at idle so under load it would be worse.
Your advice is greatly appreciated.
