Heck yeah. My thread gets some attention! Ever fix your frame Mike?

To cut the AN hose I used electrical tape, a chisel, and a hammer. I don't have any pictures of the fittings but these are the exact fittings I used



I went with the S&P adapters but search for minime168's thread on the adapters and there's a link to a cheaper source for the adapters and they're not chromed out lol

I hadn't seen that you replied, thanks man. I did order the parts from your fitting diagram and they are now here. The adapters are 12mm x 3/8" and 16mm x 1/8" right? I really don't care for the chrome either, but that doesn't seem to be a link lol. Maybe you forgot to link it? Thanks again!

Edit- haha just noticed that the welcome to the site was a welcome not a link to the site that sell the adapters. I'll check out minime168's thread. Thank you for the welcome man, I had seen you over at FSC as well. I have always just been more of a lurker.

Thanks, I saw that one last night and ordered the adapters from speedwaymotors. After I ordered I saw that they sell both 12mm and 16mm by 1/8 npt. I thought that for the swap we need 12mm x 3/8 and 16mm x 1/8. I guess I'll find out here soon.

let me know if you do get 12mm x 3/8npt i also needed for the temp sensor , their website says different!

Well, i cheaped out and am just going to use rubber hose to adapt from the stock TBI lines to stock EFI lines (got the complete fuel line assembly back to mid-cab from the guy I bought my trans from, figure I may as well make use of it. Still kinda wish i'd gone the fitting route, but.. it is what it is.

Welcome to the site!

ok so im confused on how you did this. This 89 has stainless steel braided lines from the filter up to the throttle body already. So how do I convert it to the 5.3 fuel line fittins? Or can I just cute the braided hose and hose clamp onto the fuel rail?

Put hose ends on the braided lines (if they're not already) and get the adapter from the hose end to the rails. Basically you only need the left half of the diagram you quoted.. someone already made the changes on the right hand side for you (maybe not the same, but having the same effect)

Just an update for others doing this, the oil sender adapter from speedway worked perfectly. The water temp sender adapter, not so much. looks like it is supposed to be 12mm x 3/8 npt not 1/8 npt. So in summary, use the speedway brass 16mm x 1/8npt and the S&P 12mm x 3/8 npt. I will be ordering one on monday. /End thread jack
