I lost interest for the past several months but now I'm back in the fight.  I've been taking care of a lot of little stupid things but finally got the courage to tackle the firewall.  I knew this was going to be painful and I was right

LT/LS Swaps / Re: Fuel Line Question

« Last post by devildogmech on May 31, 2025, 04:12:38 pm »

I'm using something very similar. It's like the pipe on the sending unit is the wrong size........ I'll go to AZ with my piece and see if I just got the wrong sending unit.

LT/LS Swaps / Fuel Line Question

« Last post by devildogmech on May 28, 2025, 01:35:52 pm »

ok.... Truck is a 79' C-10 BIG Ten. In the midst of an LS Swap.

Fuel System.

- NEW Tank for an 87 C-10 with TBI
- NEW Sending Unit for TBI
- NEW Pump for LS

I'm trying to fabricate my fuel lines and weirdly, the connectors for the fuel injection system will NOT connect to the sending unit. The 3/8 Feed is WAY too small, the 5/16 Return is too big. The sending unit has the fuel injection style connectors........ Is there another size I don't know about?

Thanks in Advance.

Thank you very much for the reply. I will have to check if the radiator is original and then buy a new one. Anyway, I have only found a new one on Ebay, coming from the States.
best,

Instrumentation / Fuel gauge off ?

Did you ever figure this out? Was it the resistor? Bad gauge?

Fuel Systems and Drivability / Re: Gas Station pump keep shutting off whil fueling

You aren't flowing fuel into your tank fast enough to prevent fuel from being drawn into the safety valve on the pump. What is YMM of your truck? The fuel filler changed designs several times over the years and got larger with a larger vent. Do you have a functioning fuel tank vapor vent? If everything is as it should be and you have the earlier smaller filler, holding the nozzle upside down or further back helps. Also, don't go full throttle.

Sorry, it's a 1981 Silverado 3/4.
Don't know about the vapor vent.

Thanks for the tips.

Just a follow up.

Went with a regular duralast gold thermostat and the aluminum / silicone gasket from Amazon. Working well with no leaks. Thanks guys. Was skeptical of the gasket at first but dry all around.
