TPI swap help needed

[g2bird]

So after much research and checking out what some of you have done I decided it would be a good idea to swap to fuel injection.  I ran across a killer deal on a speed density TPI setup I couldn't resist.  It has everything, except a fuel pump.  I was searching around and, correct me if I am wrong, I will need a sending unit out of an 87 and a fuel pump capable of flowing at least 45 PSI.  I was researching and the pump for an LS motor (AC Delco EP381) is the same price as those for a TPI but the LS pump can flow 65 PSI with less amperage draw.  Would that be over kill?  Any reason it would not work?

For those that have done a TPI conversion from carb what problems did you run into that I might need to be aware of?

Thanks

I have done some more checking and it seems as though the EP381 is from the vortec trucks and such. It is supposed to be a direct fit into the 87 fuel sending unit, and still produces 65 psi.  I have found lots of information that say these pumps are more effecient and draw less power while producing greater flow which seems like a good deal, but I can't find anyone who has tried it with a TPI, or at least will share that experience yet.  I'm assuming that I need the passenger side sending unit since the tank in the 79 is on the passenger side?

Get the correct sending unit for the applicable side. Just use the TPI fuel pump.

I would just get the TPI pump,  AC 241 is what it should be.

Sending units are side specific.

Thanks for the help.  I was looking at either doing that or a Walboro GSL392 in line pump.  Really only reason for the in line is I think I could get it done a little cheaper but I don't know about what to do with the return line with my current sending unit.

g2bird, the Walbro in line pump runs $125 at summit Racing. You can get the AC in-tank pump that CaptKaos mentioned for @ $72 at Amazon.com. It will be all you need in a fuel pump and considerably more reliable than an in-line pump. You can also replace the fuel pressure regulator with the XtremeFI unit to use the higher fuel pressure.

Thanks.  I saw that AC pump price.  I should have added that my truck is a 79 with a mild 327 in it and I would have to get an 87 EFI passenger side sending unit too and the cheapest I found was around $85 so the total for the 2 is more.  Unless someone else knows a good source.  I think the in tank is the better route to take.  I'm just trying to stretch my dollar as far as I can safely.  Would a whole sending unit out of a TPI car vette/fbody work or am I asking for trouble?

you need a sending unit out of a pickup.
