Okay, I have an 87 TA that was formerly and LG4. Now it has a splendid little 350 in it. The problem is the damn 87 T/A's came with two fuel pumps one on the motor and one in the tank. I decided instead of the afpr to run a mechanical at the block. Now can I use an LG4 fuel pump on the block without worries or no? If I can't I need to know what kind of fuel pump I can run at the block, it needs to be a 3 way, with the tank line, carb line, and return line. Let me know the part numbers I can use so I can pick one up at "The Zone" or something.
Thanks

 

Could someone please help me, I would like to be driving the car by Thursday

 

Stock pump works just fine. Bolt it up and go. If you start making good power or add something like N20 or Super then you definately need to replace the pump.

 

Okay, well right now the car is at the shop getting a couple of holes in the block plugged, gauge openings. Right now the motor has a 2 port fuel pump, just OEM replacement for a 72 Monte Carlo that has a 350. The shop is just 2 or 3 miles from my house, since i have by fuel return line plugged right now I am wondering if I can just drive it home and then switch to the 3 port. Would this be okay or do I risk blowing out the carb?

 

No problem. When the two-port outlet pressure gets up to max, it justs quits pumping. The purpose of the return in the 3-port is to keep the fuel circulating so it doesn't pick up as much heat, not to bleed off excess pressure.

You might have been a little happier with the in-tank and 3-port mechanical combo. But, I'm running the 3-port mechanical (AC replacement from Checker) with absolutely no problems.

Did you remove the in-tank pump? The mechanical can probably pull through it, but it'll just make it that much harder for it.

 

Great, well I have a OEM 3 port fuel pump for a 305, shouldn't have a problem running my car with it. I just wanted to make sure I didn't need to worry about excess pressure because the electric pump is still wired up. The reason why I was concerned was because I don't really want to get a flatbed to bring it home or pay the shop it is at to install a fuel pump. And I don't really have enough time to trailer it over myself. Thanks a lot guys!
