Stock TBI fuel tank—diesel conversion replace or not? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey all,
I'm in the planning stages of a '91 12v conversion on my '88 R20 Suburban. I'm using the stock Cummins lift pump (on the block)

I've heard different opinions on using the stock TBI sender and fuel tank, should I plan on replaceing both?

Its looking like a tank and GM (diesel) sender would run me about $225 + shipping. If I need them I'll drop the money on it—if I can avoid it, I could find something else to spend the money on!

Thanks
~Dave
