Hi
I was in a similar situation a couple of years back. Most people were actually removing the main pump under the car and installing a high flow uprated in tank pump which apparently works well. But like you I didn't want to do that if you search online there are some direct replacement pumps (Bosch 044 I believe) but depends what fuel pump (mk2 model) you started out with. I started out with an 8V digifant before I did my VR6 conversion and found that a company in the US did a nice upgrade link below. Don't know if they still do it also when I purchased it pound was a lot stron
Just got some pictures of my fuel swirl pot that will be used to feed my belt driven Aeromotive pump.
It will be fitted in the hole that used to be occupied by the standard fan intake.
P-motorsports alloy fabrication is second to none, just look at those welds[emoji851]
