Note that this is a return system used on my 2000 LQ4 donor motor.

Also note that the first 3' of the fuel lines from the fuel rail are original from the donor vehicle.

That looks great, nice work!

Beautiful and complete work you did there. this will be saving a lot of people some headache.

but I must ask.

Where are you getting these prices?

I have not been able to find these items at these prices. with the exception of the fuel tank(s) everything else is 50% to 100% more.

I am to the point where the fuel system is next. I am putting new gaskets on the engine and it will be ready to drop in. I am anxious to get it running.

any info on where to acquire said parts other than the one site you already mentioned would be very much appreciated.

Thanks in advance.

Ok i take that back.

the fuel pumps and sending units are the parts that seem to be the differently priced parts.

Sorry

best i could find was the sending unit at 73$ shipped and the fuel pump for 54$ shipped.

This is my extreme budget build. thanks again for the info.

::EDIT:: I never thought to look at amazon for car parts. never crossed my mind. woops.

Thanks dude!

Apparently this old guy needs to learn to ebay search a 'lil better.

I swear I did ebay search and the fuel pump auction didn't come up. The sending unit food but the 14$ shipping charge was a put off. Maybe since I am doing dual tanks I can get a break on shipping.

Is this a high pressure pump for a flex L S engine?

**truckdude239** · 04-04-2016, 12:43 PM

Its cool i just ebayed the part numbers lol

ssmonte18 · 04-05-2016, 11:04 AM

If anyone needs a fuel injected sender for a stock 16 gallon tank, I have a brand new one that I am no longer going to use!

**truckdude239** · 04-05-2016, 09:59 PM

Its the one i a running so i hope so lol

I'm not sure about your pump? Even the stock pumps are barely adequate past a stock set up. You may see good psi idling, but going down the road under a load is a different story. If nothing else at least run a 10 gauge hot wire with relay. I know you will get a lot of people who may say I'm full of it. But it is the exact reason my lq4 was going lean running a stock ls1 pump with a small cam.
