Cool blue! That's nice

I wouid recommend NOT using a sump for the fuel supply, they are illegal for good reasons.
ALL vehicle fuel tanks are required to have all fuel lines running through the TOP of the tank. Look at any well-made race car and you'll see they are done that way too.
The DrawStraw setup works great, there is no 1/4 tank issue if you install it correctly. You need to drill holes in the basket.

Good advise^^^

 

[Derekp]

It's already installed bud. I wouldn't call what I did to my truck completely legal anyways. I took out an egr emissioned gas motor from a late model truck and put in a 1990 straight piped diesel into the same late model truck. I'm not sure I'll find the rules on that in the handbook.

I'm a hot rodder too and I like your truck a lot. I used to get my F150 that I swapped a very not-stock '68 428 into past its emissions test by running about 75% alcohol during the test. I've done lots of not-by-the-book engine swaps.
I'm just mentioning this since the thread seems to recommend sumps to others. If the hole in the bottom of the tank isn't already there, run a drawstraw.
The famous 1/4 tank issue can be solved by modifying the fuel basket in the tank and making sure the pickup is at the right height.

I appreciate it and I'll take your advice. I researched the legality of the sumps but I couldn't find a clear answer on the issue. I've already installed one on my truck and there is already a 3" hole in the bottom of my tank so I'm pretty sol. I'll mention it so others to research it if they decide to go with it to see what they come up with though.

I put a sump draw on mine no problems and I've never heard anything about it being illegal except maybe for racing
And im sure if it was illegal there would be a disclaimer. "for off road use only"

Racing was all I could find while researching in regard to it being illegal.

I know the state dot has enuff problems. Just enforcing laws without something like a sump draw too

I think he meant during inspection though they might give me a hard time. I actually live in a county that doesn't have emissions and we are business partners with the shop that does our inspections so I'm not worried about it.

You know what, I think I'm mistaken, it appears there's an exemption for diesel fuel...

FMVSS 393.67) 7.4.5. Fuel withdrawal fittings. Except for diesel fuel tanks, the fittings through which fuel is withdrawn from a fuel tank must be located above the normal level of fuel in the tank when the tank is full.


(f) Fuel lines. A fuel line which is not completely enclosed in a protective housing must not extend more than 2 inches below the fuel tank or its sump. Diesel fuel crossover, return, and withdrawal lines which extend below the bottom of the tank or sump must be protected against damage from impact. Every fuel line must be—




(1) Long enough and flexible enough to accommodate normal movements of the parts to which it is attached without incurring damage; and




(2) Secured against chafing, kinking, or other causes of mechanical damage.

 

[Derekp]

Interesting. Thanks for posting that. It looks like as long as the line is protected from the sump then it is okay.

Off road a bit.

Derekp doesn't it worry you to have that filter sitting that low

Yes it does. It's getting moved here soon. The company I ordered my fass from didn't send me enough fuel line to put the pump anywhere else. I have a 26 gallon tank currently in the truck and I managed to find a 34 gallon that bolts up. I'm going to swap everything around soon and move my pump with the extra line I bought. It will be next to the tank up top under the bed.

 

[phantomusa]

Ok I saw it sitting low and I know it would worry me that something would hit it and start dumping fuel on the ground
I worry about my sump draw fuel line snagging something so I built a angel iron shield bolted to my frame to protect it
