Fuel tank related questions

[SkysTheLimit]

How would I go about disabling the in tank pump and making my TBI sending unit function as a carb unit would? I have an external electric hi flow fuel pump.

First thought was just unhook the fuel pump but it would probably restrict flow. Be better maybe to just trade someone their carb unit for my TBI?

For the record, dropping the tank is a royal PITA!
Anything else I should do while I got it down? Probably go ahead and shoot the frame rails with some rust bullet. I'm going to paint the tank too for giggles and grins.


thx!

why do you want to do this?

Because short of dropping 2 grand on a commander setup, i have to run carb to feed my new engine. Stock TBI can't keep up.

How about a regulator with the stock pump?

I realize an engine as large as in your signature is going to need more fuel than a TBI 454, but will a stock pump flow enough?

Never have checked to see if a TBI 454 and 305 or 350 use the same fuel pump.

I looked into it. Apparently the stock TBI pump will flow enough for a mild 383. I have a wild 496 so no dice. I originally was going to throw in a Aeromotive bypass regulator and be done with it but when I looked around I found some posts in a tech support forum from a guy with a warm 383 who wasnt getting quite enough flow.

I know the new pump and regulator I have will work so i'm sticking with known good solution to get this thing back on the road.

So what's the best way to go about this? Trade out sending units?

Anyone on here doing a TBI/TPI swap would be crazy not to straight across swap sending units with you, given that yours works correctly.

That's what I thought. Mine works just fine. 94k miles on it. I'll post up an ad in the wanted section.

Thanks

I WANT YOUR TANK!!!!!!!!

I am doing the swap to TBI and need a tank and sending unit. I have the stock tank from a carbed 73 K5. Now... how do we go about shipping em....

Edit: Hell it would almost be worth the drive down there, since I have family in Orlando...
