89 W-250 TBI to Carb?
 

I have a 89 W-250 I am going to switch from Fuel injection to carb. I am changing dist. and putting on a 600 Edelbrock carb. My question is about the in tank fuel pump. Should I run a regulator with bypass or can I add a inline electric fuel pump and will it pull fuel through the in tank pump if not hooked up? Thanks, Todd

interesting...im not sure if there is anything to prevent the inline electric filter from drawing through the stock filter...

You'll have to remove the in-tank pump and install either an in-line electric or conventional mechanical pump. The TBI pumps run 5 times the pressure an Edelbrock carb can take.

Ive heard of guys still running there in tank pumps but just "unplugging" them and runing a inline electric fuel pump, I really dont know if it works though...

I have an '88 318 that had TBI. I installed a cast 4 barrel intake. You may have to remove the intank pump and lengthen the pickup tube and screen .I don't think it will draw throught the pump. My engine is in a '63 panel using a different tank. My big problem is the distributor. My engine has a hydrolic roller cam, yours may not, but I cant find a dist that will work. An older point type dist is 7/16" too short and will not engage the drive gear. I'm still looking for answers.
