IR89 - back in action.

Well, I sit here trying to figure out exactly how to do the fuel pump I think this is the best Idea I have, but opinions are welcome.

This is how the Walbro 450 E85 pump sits on the stock hanger, without the isolator. As you can tell it doesn't line up, but even if it did, the standard rubber line is a little too small for the output side of the pump. I could easily cut that tube back to a point where a hose would connect if all else fails, but I want to try and keep the fuel feed the same diameter all the way through the system. (1/2" OD, aka -8AN) to keep the pump as efficient as possible. The outlet of the pump itself is just shy of 1/2" at the flare for the hose. I am going to go buy a length of larger fuel hose and see what fits before I make my choice.

Anyway, what I think would work best is to cut the tube off of both ends, of the plate and drill out the hole, offset a little, to accept a -8AN bulkhead fitting. It needs to be offset to avoid clearance issues with the bulkhead nut used on the inside.

Here is the two coils of 316L Stainless steel tubing I bought for my fuel lines. 1/2" (-8AN) and 3/8" (-6AN). 25ft lengths, so I may have some extra...

That's the advantage of leaving fuel in the tank.

It was only at half a tank, but there is zero rust, even above the level the fuel was at. I was expecting worse after seeing my share of stored vehicles that sat for years with less than a full tank.

Full tanks are usually ok, it's the partially filled that are bad, especially if only finger deep.

That is one advantage of plastic tanks - provided they don't crack or cause static.

I got the chance this week to spend more time getting my garage in order, and the rest of what I was waiting on to get my fuel system built finally arrived (and a few things for the turbo oil and water lines as well, minus 4 of my -6AN hose ends that are on back order). I don't have everything I need yet, but they all need to wait until other stages of this build can finally be reached (waiting to get power setup for my welder). I can hopefully get started on it Sunday... I volunteered to watch my buddies kid tomorrow, I am replacing the bad cat and doing the suspension on my Vic Friday, and huge family get together Saturday for birthdays (mine included so I have no choice but to go lol). Hopefully I can at least find a 1/2" tubing bender before sunday, because I just happen to not have one and didn't think about it...oops. Luckily I already have my 37* flare tool for stainless tubing. ( I think I may make a side business out of this for a little extra money )

Also, for anybody looking to run E85 with EFI, that fuel filter below is exactly what you want to get. It is a Golan racing 10 Micron EFI fuel filter with a washable/reusable stainless steel filter element (or you can buy new ones if needed). At $85, they are on par or better than most other brands out there, and are the only one I found with a metal filter mesh capable of 10 microns. http://www.jayracing.com/index.php?main ... cPath=2_14

That reminds me of how shocked I was to find that externally braided ss brake lines will not pass a roadworthy here.
I had some made for my Ducati when a fitted a second disc & caliper to the front wheel some years before.

Yeah braided lines are a no no here. Pity.

Most of my lines are actually going to be the stainless steel tubing. The braided PTFE hose is for the connection to the gas tank, and from the hard line to the rail, and then to the regulator. Most of it is actually for the turbo coolant and oil feed.

I want to use as little as possible, but it surprises me that the braided lines are not road legal. I find them better than standard rubber, especially the PTFE core like what I have.

IZU069 · Post by **IZU069** » Fri Mar 08, 2013 9:45 am

I inquired why they were not legal. It's because you cannot inspect the condition of the sleeve (rubber etc) under the braid.

IMO it's a valid and important point for "normal" vehicles.
Different if you compete or replace them every few years. (Noting that many sources will say to replace flexible hydraulic lines & fuel lines every few years (from 2 to 5 years). Obviously they aren't aware of Isuzu quality.)

That makes sense about inspection. I never even considered that aspect of it, but I also replace the hoses roughly every 3 years. The nice thing about AN hose ends is that you can actually re-use them, so that makes replacement much cheaper since the ends tend to be the expensive part.

A new present finally arrived. Been waiting weeks for these lol.

Nice looking rods. Any reason why you went with pauter?

ImpulseRocket89 · Post by **ImpulseRocket89** » Fri Mar 08, 2013 5:50 pm

Yea. Personal preference. I used them before on a different car, and while they are heavy and expensive, I have no fear of damaging them in any way unless I severely screw up somehow. Overkill = my way lol. Pauters are run in cars pushing a lot more power per cylinder than I will probably ever make (1000+ whp Supras etc)

Aside from being functionally invincible (so I am exaggerating a little) The balance the rods have and quality of the part and materials themselves are second to none for the price you pay IMHO. The only way to really do better would be to have top of the line custom rods made by Oliver, and possibly Carillo (which I feel is close to the same).

Well, my radiator is being made and should be done either Friday, or no later than Weds. of next week. I finally got in contact with JE, but then the guy forgot to call me back again... getting really frustrating.

I got my Speedhut Revolution gauges in, but I have to think of another solution for gauge mounting instead of that 1 Din panel I have (thankfully it was cheap). I would have loved to put them in that spot, but even if I made my own panel to work in that spot I don't think all three are going to fit in that spot. ( I will try and take a picture as to what I am talking about if I can)

My first plan is to try and make a cardboard template to see if I could simply make my own panel that would work in that bottom position, but if that doesn't work out I was considering maybe something similar to this on the top of the dash.
