Gettin my surge tank installed this week. Still debating what pumps to run.

Cool, I know what a surge tank is for but know jack **** about how they work or installing them. That's going to be external to the tank right?

Didn't you have a hellcat pump?

In other fuel news but not related to FI Honda, a few weeks ago I put a new fuel pump and tank into the Mustang. Have gotten done with a lot of needed maintenance items on it and is finally running great. Compression tested the old 302 and basically 160 across the board, great candidate for heads and cam.

(No the Mustang is not what was holding me up on the Civic, should finally be working on a couple small items this weekend)

The main tank is now going to have a 255 pump feeding the surge tank. The surge tank feeds the fuel rail. The fuel returns now to the surge tank. The surge tank has an overflow that will route back to the main fuel tank.

This will allow me to run the main tank very close to empty. Right now anything below half tank and the pump cavitate under hard turning

That is interesting.

I remember you mentioning that problem several months ago. Did you ever try that Hydromat thing or whatever? If I recall you weren't entirely sold on it.

Pepe14

The surge tank was cheaper than a damn hydramat

Ive always known the surge to be the right fix

I was originally going to use the stock -6 line for the return but decided to just redo it all up to the firewall with 3/8 alum tubing since its so cheap.
The surge tank has stainless tubing but was expensive at 6 bucks a foot. A roll of 30ft aluminum tubing was 25 bucks.
I got a little more done today. Removed the rubber hose on the return from the flex sensor and i added in an adapter to a -6. I got the fittings on the fuel rail setup. Im going to have the engine bay lines made last with proper compression fittings and nut push lock/twist hose. I should get the clamps for my fuel filter tomorrow and i can mount that and then just bend up the line under the car. I re routed the stock lines from the main tank to the surge but im going to redo them. I can do better.

Heres a pic of the fuel filter i was using. They say more surface area the better. This filters down to 7 micron
Its a 2” body. Kind of a pain to find a place for it.

Pepe14

Filter mounted

Fuel system is finished. No Leaks, Im just going to photo dump from now on.

Going to do a side skirt exit exhaust and add a resonator.

Boom tube!

Are you going to add any crash protection/firewall around the surge tank?

Any plans to relocate your screen into the dash? Do you still need the gauge cluster at this point?

Pepe14

is there crash protection around my gas tank? Ill most likely add a plate surrounding it just to the quarter panel in case it leaks but it shouldnt ever leak for no reason.

Ive been debating the screen in the dash but not sure how good the visability will be with the steering wheel in front of it. Plus I already spent 100 dollars on the damn windshield mount.

At this point its only for diagnostics and my lap times. I have it mostly showing my lap times when im out on the track. I rarely look at my rpm or speed.

Caoboy

Are you running a fuel cell yet?

I was just thinking some sort of protection against potential fuel leaks in the cabin from lines breaking in a crash.

Pepe14

No and I probably wont need a full blown fuel cell for a while.

Got the exhaust almost done. Just waiting on some isolators

Very unique exhaust, piping looks good. Take some wider view outside shots? Curious to see how it sounds too, I'm guessing pretty loud.

Also Pepe, you're just running a baffled pan as far as maintaining oil pressure right? No accusump?

Pepe14

Its actually a lot quieter at idle. Ive added a flex tube, resonator and oval tube. It’s definitely going to change the way it sounds.

Im waiting on the grommet to show up today then i can finish up and lower it on the ground and take a wider shot.

Ive got a baffled oil pan and also an acusump.

Pepe14

Got the high temp grommets pretty late today but will be all welded in place tomorrow

Pepe14

Exhaust is all mounted up. Definitely sounds better. Ill take another video with the go pro in the car.

Chance EG

Big difference on sound, sounds much "fuller" and more mature now I think. Deeper.

ls joker

Without watchin it with my surround sound on, idle sounds about the same. When you rev it a bit, it definitely sounds cleaner. Not as raspy. Which is likely from the resonator

Pepe14

I just drove it around the block and it sounds soo much better. I can actually hear the bov now lol.
