Brian said he'd give you a reach around? I guess that's fag talk for foreplay

Ruben says after stock filter, and Jason's is before the filter... ok to do this either way?
Ive done two where i just ran a new line from the lift pump all the way up the drivers side frame rail to the front accross through a cooler and around to the factory filter. eliminates the supply fuel running across a hot engine as well along side of a hot trans, has to help some!

Either way is just as easy. I did mine before the filter just because i wanted as little as possible after the filter.
I'd just like to point out that the fuel return line dumps into the same little cup below the sending unit that the system draws from. Helps keep the cup full, preventing you from running out of fuel when the tank is low. So essentially the fuel is running in a constant loop getting hotter and hotter with every cycle. The quantity of fuel in the tank will not have a substantial effect on the temperature.
moparkxracer, do you have a part number for that cooler? and it doesn't look like a fan correct?
It is part number 30416 from Fluidyne, no I am not running a fan on it. I didn't run the returns from the lift pumps trough it, just the returns from the cp3's, injectors and fuel rail returns. I was worried it would fill air if I tired the lift pump returns into it. I also didn't want any restriction on lift returns. I may have other pics I can text if you'd like. Just pm me your number and I'll send them, space is limited on here.
You are wrong. The quantity of fuel in the tank has a lot to do with fuel cooling.
I have done extensive testing on this.
i know on my single ad2 165, i pulled my return line at the cooler to fill a gallon jug with diesel and had no foam/air to speak of. the particular line i pulled was after where the return line from the pump hooked into the factory return line so i was seeing all return flow.
Would a trans cooler in the stock location yield cooler fuel temps or would a different location be a better choice?Very interesting topic!
Your stock cooler is restrictive. Try blowing through it and you will see. I shit canned the stock cooler and used a twin fan Setrab mounted in the frame rails just in front of where the old cooler was mounted. I used an infra red camera to test a lot of things. My camera showed very little drop in temps after exiting factory fuel cooler, but made a dramatic drop in temps when the return fuel hit the tank. With the Setrab twin fan cooler, we saw an immediate drop in fuel temps as it exited the Setrab cooler The lower the level of the fuel in the tank the less temp drop was seen.
We should never run lower than 1/3 tank of fuel so that the fuel cup always stays submerged. When the fuel level gets below the top edge of the cup; it start to feed from the flapper valve sitting just above the tank floor and the return fuel. You will lose horse power by letting the fuel get that low. I think this can be data logged with EFI. You can watch the fuel temps get hotter as the tank gets lower.
Its a pretty simple concept...... The bigger the pool the longer ( or more energy) it takes to heat or cool for that matter.
Interesting read, I've never deleted a fuel cooler myself but its common around these parts for guys to bypass em when they rot out. Also makes me want to see what my LMM is running for fuel temps pulling a long hill.
Care to send me a link on the cooler/fans? unless you still have one laying around
Sorry I don't have any left James. You can make one pretty easy. Just make sure it is free flowing. If you have a hard time blowing through it; don't use it. The fuel needs to move quickly and unobstructed to work.
I don't think it matters where you mount it. I've done it on the return line and feed line.
If your fuel gets hot, you will lose mileage and power. Installing a fuel cooler will give you your lost mileage and power back, and then some.
