I'll be listing these shortly in the FS section with pics! Prices are $319.99 for these harnesses and include a NEW 65 psi GM style selector valve!

check pm please.

I am literally building a Frankenstein truck 74 k20 chassis with an 83 body and a 90 tbi top on an 84 short block the truck is a single tank but the bed is dual tank so I’m adding a second tank as not to add to body and paint. Your harness is just the ticket for what I am doing. I’m looking at the Howell wiring harness and hoping that your Hermès will interface with his? Can you give further guidance on that topic or what I need to do. Thanks for the response

This is 100% stand alone requiring only a fuel pump output trigger from the PCM or, you can simply use a switched 12V IGN source.

Still selling these?

superpug · 03-10-2021, 10:22 PM

Big reach, here. Are you still selling these? I dropped my truck off to a shop that got recommended to me for LS swaps while I was deployed. Turns out they dont know how to wire. So I have one operable fuel tank. Its already got dual Walbros in there. After that I have no idea what they did...So I'm just going to try my hand at it.

Also...I uhh have been lurking here a looooong time.

Hi there. I’ve been on the same hunt recently... found that the gmachinz guy is still selling harnesses, look up user Jabin Wood on Facebook marketplace. Also received this link from another user on here, to a company that produces a similar setup. Haven’t called them yet but I like their options. Be sure to post if you end up solving your issue!

Just a thought, if a vendor has a suspended account here, you may want to search the site for reviews on their services before transacting with them elsewhere.

I believe gmachinz was suspended for taking orders and not fulfilling them or responding to inquiries about order status.
