veritech-z Posted March 13, 2007 Share Posted March 13, 2007 INPUT!!!! Just out of curiosity, are we talking about just reducing the amount of "trumbone", or are we talking about switching to something like the JSK rail featured in this picture of my engine bay?

wonderllama Posted March 13, 2007 Share Posted March 13, 2007 i love that picture of your engine, i want to hire you to make my engine look that clean Quote Link to comment Share on other sites More sharing options...
veritech-z Posted March 13, 2007 Share Posted March 13, 2007 I really appreciate it, but it still tickles a little bit to hear it called "clean". You know there is no fuel injection wiring harness in that engine bay? That counts for alot I think...I tell you what, I'll take a current, engine running picture tomorrow and if you still think it looks that clean we can discuss my hourly cleaning bill...also, you'll have to fight RonTyler for the rites to my rusty header...

wonderllama Posted March 13, 2007 Share Posted March 13, 2007 heh. well, dont make me take a picture of a stock 78 with the egr, air regulator, pcv, etc. the fuel rail makes a huge difference as well. Quote Link to comment Share on other sites More sharing options...
veritech-z Posted March 13, 2007 Share Posted March 13, 2007 Oh don't worry, that engine bay wasn't always the paragon of minimalist design that it is today. It was once a real live untouched 1977 egr L28. I did put a lot of work into grinding the holes off of that manifold (I even cut off and then epoxied shut the EGR hole), but it's nowhere near as nice as most of the other guys that are justifiably proud of their clean manifolds and engine bays. I did just drill out the spot welds holding the charcoal canister and MAF brackets (I'm on megasquirt so I didn't need them anymore) the other day, so it's a little cleaner in some regards, but messier in others (not all my wiring is loomed or hidden).

tybaldo Posted March 13, 2007 Author Share Posted March 13, 2007 linec you are saying that i can just cut off the xtra piping from the fuel rail to make it shorter and it will be fine. correct me if im wrong? Quote Link to comment Share on other sites More sharing options...
veritech-z Posted March 13, 2007 Share Posted March 13, 2007 Exactly which part would you like to cut off? you could circle it or whatever in MSpaint or photoshop, and repost... Quote Link to comment Share on other sites More sharing options...
LineC Posted March 13, 2007 Share Posted March 13, 2007 What are your reasons? As long as you have inlet outlet and the regulator you should be fine. Some people even do away with the return line but I personaly wouldn't do it. Quote Link to comment Share on other sites More sharing options...

Some people even do away with the return line but I personaly wouldn't do it. Does your regulator still work without a return line? Unless you get one of those restrictor deals that just pinch the line to lower the pressure, I don't see how it could...I assume he want's to clean up his engine bay, that's the only reason I can think of to do it. The easiest (albeit not necessarily the cheapest) way is to get an aftermarket rail, or go to some place like http://www.rossmachineracing.com/index.htm and make your own from some universal rail sections. I got mine from Ebay bundled with the throttle body spacer to use a KA throttle body for around $100 or so, it's been awhile.

LineC Posted March 14, 2007 Share Posted March 14, 2007 Is that Krylon black? What is the crazy tee on the valve cover? Is the pressure line splitting for the inlet and outlet through that T??? Quote Link to comment Share on other sites More sharing options...
veritech-z Posted March 14, 2007 Share Posted March 14, 2007 That's actually wrinkle finish black, and the braided lines have rubbed some of it away a bit since I've been fooling with my injectors so much recently. The Y fitting up there was originally a low restriction solution to get fuel into both my SUs that I was running, and since this fuel rail had a provision for several 1/8NPT fittings in addition to the 6 injectors, I decided to keep it and put the pressure gauge in one hole, and use the hole that used to be for the cold start injector to be the FPR feed line. I had heard a theory that feeding a fuel rail from both sides is supposed to give you more consistent feed to all your injectors...I can't say really if that's true, but it looks cool and it definitely doesn't hamper my fuel flow that I can tell.

tybaldo Posted March 16, 2007 Author Share Posted March 16, 2007 the red circles are where i want to cut the fuel rail. and the red line on the bottom is what i want to keep. would it make a difference Quote Link to comment Share on other sites More sharing options...
X64v Posted March 16, 2007 Share Posted March 16, 2007 Yes, you can do that. I ran one like that for a while. You'll have to block off the cold start injector port and the old return port that come off of that line of rail. Just remember not to cut the ends too short, because if you do, the sharp edges will cut through fuel line like no tomorrow (ask me how I know...).
