yeah ive done the search. but i cant find WHY you have to take the pump out. my swap is done and it will not run because i forgot about the fact that you cannot pull gas thru that pump. So while im ripping out the pump can someone explain what it is that keeps fuel from being pulled through the pump? I have a c-10 pickup that i went efi to carb and left the pump intank and it works fine. so im a bit confused what the diffrence is. thanks

 

What swap did you do? From TPI to carb, judging from your screename. I guess you got lucky on the C10, but if pumps were free flow then how could they pressurize the fuel? Was the pump working beforehand? If I were you I'd find out how to turn it on and see if it can be used with the new setup. I'm pretty sure with TBI you can use the pump and then only need a bypass regulator. Wish I had that setup over the mechanical actually. Your TPI pump might not like low pressures.

 

it worked fine, pressure i thought was all controlled at the rail.. and yeah tpi to carb. i have mechanical on there now, did the price match of a stock 350 pump or a regulator, pump was cheapest.. it puls through but just barely.. not enough to keep it running

 

Sometimes it works, sometimes it doesn't. Best approach is to pull the in-tank pump if you're not going to have it operating.

 

yeah im in process of doing that now. i cant find the thread about what to use but cant i just remove the electick pump itself and use whats left for the pick up?

NP. Hopefully you could see the cyber tongue-in-cheek.
