Hello,
About 7 years ago, one of my good customers wanted fuel injection on his 1967 122, but at the cheapest cost and I suggested putting in a B20F with the CIS injection.
He agreed to a price but would not wait the 6 months I needed before tackling his project.
My customer went to a Saab shop near his house and had the Saab mechanic install a used B20F and with one of the worst and most dangerous conversion techniques I have ever seen, the car was a rolling bomb.
The Saab mechanic installed the in tank prepump and return lines by drilling a pair of holes in the stock gas gauge sending unit and installing pipes he sealed with the emergency gas tank sealing putty you can buy at some auto parts stores. He then just hung the prepump on the end of the one of the pipes inside the tank and used the other for the return line.
When you filled the tank, the recess that the sending units sits in, would fill up with gas and stick up the whole car and when you got to about 1/4 tank and went into a turn, the car would die because the gas would slosh away from the prepump pickup.
To solve this problem, I cut apart a 240 Volvo gas tank and had my local ReNu shop install the 240 gas sender/prepump gas tank access hole to hold a modified 240 sender/prepump assembly on the side of the stock 122 gas tank and then welded in place the bowl that holds fuel around the prepump into the bottom of the tank. This required relocating the stock sending unit.
This fixed the gas tank problems and made the supply line and the return line locations to not be inside the trunk.
