I can't remember if I do or not. I'll have to check.

Kjones, what what the pump off of? There are mods that can be made to the AFC to alow more travel out of it along with modding the diaphragm. My guess is that your fuel plate is pulled back and limiting full fuel or the AFC is to far back and not letting it fuel enough. The AFC housing is the only emissions equipment I ever liked. Set it up for a ton of fuel then dial it back till boost rises. Another thought is to ensure that you don't have a leak in the AFCs boost reference line or a faulty overflow valve (pressure valve in the return line). My 175hp pump and stock injectors would black out a lane of traffic when it had a stock turbo. 500HP has been hit with pump mods and a HX35 even though it was hot and smokey. You may want to reduce the timing a little. I ran 18-19* but always had head gasket issues even with studs and orings. 17* seemed pretty safe and spooled up a little better but power also dropped off earlier.

I forgot to add that. New reference line. And I took the fuel plate out to see if it would help. It's a new rebuilt unit that is suppose to replace the 175hp that I had which had sticking issues. I've done all the mods that I know of to the AFC. Including the diaphragm. Starting to wonder if the rebuilt pump could be the issue, as the shop has a 50/50 satisfactory with the community

Kjones72, your timing sounds low to me for a P-pump 24v. Mine is set at 25*. I wouldn't go much lower than 23* personally. Sorry for the late response. I didn't see the new posts.


It may be too late to buy the mag off the stands now. The Vette was in Ultimate Diesel Builder's Guide October/November issue, instead of Diesel World. I had a hard time finding a copy a few weeks ago. It seems they were still on the racks last weekend though.

As far as the Longhorn, the trans should be done at the trans shop this week. Hopefully in the next two weeks I can get it put back together. The engine has developed an oil leak. I need to fix that before I put the trans back in. I haven't had time to mess with it with work and helping a friend with harvest.

Good job on getting in a magazine.

[Dieselwrencher]

Today I picked the trans up from the trans shop. It should be fixed now. The engine has developed an oil leak. I need to remove the engine adapter and see where it is coming from. once that is fixed, then I can get back to installing the trans. Ten I need to finish a lot of things I haven't gotten too, to make it a daily driver. Like, mount the air compressor, tank, and leveling valve. Install and wire the compu shift mini, wire the heater circuit, wire in the cab lights, cargo and third brake lights, and check the operation of the wipers. I need to re-visit the LMC heated washer reservoir as I think that may be a nice addition too.

I've read over both of your builds man you got all of work into your builds Ive been gathering parts and a lot of information and ideas from reading your two builds to help when I finally start actually building mine thanks for sharing all your hard work definitely show stopping attention getters

Congrats on the magazine feature of the Vette.Very nice.

And good to hear your back on this again.

[Dieselwrencher]

Thanks guys!

[Dieselwrencher]

Same old stuff here. The truck has sat on the jack stands all winter out of the snow, ice, hail, rain, and even a tornado. Haha I've been acquiring more parts for it, and working on it when time allows. I managed to get my right and left seat belts in. A friend came over and worked on fitting the stereo to the billet radio mounting plate. He also hooked up the front speaker wires and mounted the speaker brackets I got from Bigblock73. I removed the brackets and painted them, then ran the speaker wires and reinstalled them. I also ran new wires to my cargo light and 3rd brake lights. Now I have to get a new cargo light switch to finish that. I also got my sill plates installed. Whoops, I almost forgot. I also installed my new precision push on door seals. I had to work them around pretty good with the rubber mallet to get them to fit end to end. Now the doors really shut hard but maybe they'll seal awesome. I also got the rear main replaced, and am picking up the expansion plug tonight that was my oil leak. I sent my torque converter in to get turned back into a diesel converter too. So when its back, I can get the trans put back in it. I'll try to add pictures later.

[Dieselwrencher]

I forgot that I also ordered a 19gal Boyd aluminum tank. I had to have them change the mounting brackets, and it has a 1/2" feed instead of a 3/8". Now I have to decide on a side marker filler, tail light bed filler, or a bed floor filler.

[Dieselwrencher]

Here are pictures of the new door weather stripping, sill plates installed with SS hardware, speakers, and seat belts. I also finally got my oil pan, rear main, and cam expansion plug all done. I also got a catch can for it. I think I'm going to mount it in the LH inner fender well. Now, once the torque converter comes back, I can put the trans and transfer case back in.

Looking Good!

Looks good! I guess I overlooked it, but what did the seat and seat belts come out of? Also, are the belts mounted in the factory hole in the b pillar?

[brimc]

All looks very good!
I like the idea of side marker fill if you are wanting it hidden.

Thanks. The seat is out of a 2004 2500 Dodge. The seat belts are new and from Wesco performance. I got the ones for bucket seats (11") and the GM labels on the latches. I am pretty satisfied with them. Make sure you get the hardware kit. I did not and I had to order these when I finally got around to installing them.

Thanks. I think I might go behind the tail light because it will give the most room for a fuel nozzle.

Thanks!

Taillight filler would be good for a worker...

[COS399]

Those are some SWEEET emblems.

[ryanroo]

im on the fence with bed floor filler. what happens when you have seventy five sheets of OSB in the truck and need fuel? if i was to do a hidden it would be in the tail light. shes looking good! we want a burnout video!

I'm with ya there. Only burn outs it'll be doing is on some different tires. Haha

[watahyahknow]

either that or mount a motorcycle gascap on top of the bedside

The only problem with a motor cycle fill is you'd never get a large truck stop fuel nozzle in it. And that's a bad deal if that is the only nozzle around with diesel in it.

[rgreathouse]

Dieselwrencher I have a Boyd welding 19 gallon cell and used a 88-98 Chevy door in my bed floor. My truck being a short bed any work I do with it I will most likely have a trailer behind me, but I also was concerned about the day I have a full pickup load and need fuel. Here's some pics, the door landed where the bed support is so that had to be notched.

[Dieselwrencher]

Rgreathouse, that turned out nice!

I got some different front emblems from Shortie. They look closer to the originals compared to the ones I have on it now.

[rgreathouse]

Dieselwrencher emblems are nice! Who made them?
