? on modification of factory fuel sending unit
I relocated/changed the cab mounted fuel tank in my '70 short/step to the rear behind the diff. as many do with the blazer style tank. I'm using the factory sending unit/fuel pickup assembly I got with the kit. I like the tank application, but it only has what appears to be a 5/16" pickup tube for the fuel..... My question is has anyone out there ever modified, or changed the pickup tube in one of these factory sending units to 3/8" or 1/2", or is there any other options short of a fuel cell? It needs to feed a 460 BB chevy with 750 holley or bigger carb. and when I mash the pedal I don't want to starve it for fuel, especially at the beginning of the system. Easier to fix now, not later!
Thanks for any input

That sending unit looks identical to the 67-72 units (except for the hose connection) but I'm not sure about the length. If it's the same length you can get a new sender with the 3/8" tube. LockDoc

Re: ? on modification of factory fuel sending unit
if that is a blazer tank, then you need a blazer sending unit for a v8 blazer... they came stock with a 3/8. Get a 60/70 if you don't want a return line.
