In Tank Fuel Pump Question

I found a guy selling this tank for $200 so I picked it up from him. He had it in a late 90's chevy truck and it has a pump in the tank. I also have a new 383 that doesnt have a mechanical fuel pump. I was going to buy an electric pump but was thinking that now I can just use the one in the tank and put a regulator on at the carb. Does this sound like it will work or should I not hook up the in tank pump and just buy an electric?
Thanks

Re: In Tank Fuel Pump Question

Just drill some injector bungs on that intake and you should be good to go.
You can probably use that pump with a regulator. Does the setup have a return line? if so I would use a regulator with a return port.

Re: In Tank Fuel Pump Question

need to know if it is a fuel injector pump or a carb pump. since you said late 90's, lets assume FI. that being the assumption, you will definately need a regulator and a return line. or, like the others said, Inject your engine and no worries!

Re: In Tank Fuel Pump Question

I am also assuming it is a fuel injection pump. Here is a top view. I imagine one of these hoses is a return. Not sure about the other two. I think the guy had it running to another tank in the truck.

Re: In Tank Fuel Pump Question

Best thing to do would be to check how much pressure the pump is developing.
If it is a pump for a TBI motor thr pressure will be much less (approx 6lbs I think) than if it is for a TPI motor. From the looks of the fittings I'm thinking TPI.
Also the pump may be no good which would make your decision for you and I agree with the others go with the FI

Re: In Tank Fuel Pump Question

The pump does work cause there was gas in the tank and he hooked a wire to his battery and drained it into another tank so we could lift it. I already have the rest of the parts for the engine so no FI. What would be the best way to check the pressure?

Re: In Tank Fuel Pump Question

Get a fuel pressure gauge and connect to the "out" line on the pump. You can buy a cheapo unit and use it just for the test or buy a quality piece and install it permanently. There are tons of them for sale on Ebay or any auto parts store will have one

Re: In Tank Fuel Pump Question

Transfer flow tanks are used to pump fuel from it to the OEM tank. You will have to check local laws about using it as a main tank as it was not designed for that purpose. Just don't want you to get stuck if you go through state inspections.

Re: In Tank Fuel Pump Question

I have never heard of a transfer flow tank before. Are there any safety concerns I should be aware of? What agency would I check with about this. I am swaping tanks cause the nearest track wont let you run if the tank is in cab. Do you think they would have a problem with this type of tank?

Re: In Tank Fuel Pump Question

I don't know if they would have a problem with it at the drag strip. You could check with the company about issues running the tank. http://www.transferflow.com/ They could help you more.
