AC and gas tank redirect help
 

My 69 GMC truck does not have AC and i live down in Texas and that is a necessity. I am about to order a new system from LMC and i was wondering if anyone could give me any advise. I have a 350 and i was wondering if i should order it from LMC or somewhere else. I was also wondering if i needed to replace my radiator to an AC radiator... after everything, the new system and radiator will cost about $1,000. Is that a good deal? I was also wondering if i should move my gas tank to the rear of my truck from the cab? Is it hard and is it worth it? If so what size fuel line should i buy for a SWB... and do i have to buy a different fuel pump for the different length fuel line? thanks for the help.

Can't help you with the AC but I have moved the gas tank to the rear of my LWB stepside. I started off with a tank and sender from a '72 Blazer and plumbed the fuel inlet out the left rear fender.

After several years I replaced the old leaking Blazer tank with a new poly tank and new straps from JC Whitney. For fuel line I bought 5/16" fuel hose from the local parts store and ran it to the old steel line. Your old fuel pump will work just fine.

Plumbing the fuel inlet out the fender was the real trick. Assuming you have a fleet side you will probably want to put the inlet in the bed. If you want, I can explain how I did mine (pics etc) which involves using radiator hose because of its flexibility and welding on studs to the inside of the fender to hold the fuel inlet in place.

Is it worth it? It was to me. I like to race every now and then and moving the weight towards the back is always a good thing. Plus it opened up all that space behind the seat of the truck.

It would be better off going through maybe "Vintage Air" or Old Air Products, or someone like that, that specializes in a/c systems. As far as moving the tank I would. Recently there was a guys truck in here that burned completely inside due to the tank mounted inside the cab. Purchase a Blazer rear tank kit from one of the vendors that support the board and move your tank to the back. The kit comes complete with new sending unit and all. No need in upsize the fuel pump.

:agree: with the A/C advice. The LMC folks are just teleoperators that know little about our trucks and even less about A/C systems. If you purchase directly from one of the aftermarket A/C kit vendors, your purchase will motivate them to answer followup customer service questions. If I were installing an aftermarket A/C system, I'd have a LOT of questions. :lol:

I think I had it listed as Vintage Air before, I get the two confused a lot.
