Ordered a Holley pump with 110gph and 14-16 psi regulated pressure today. <br>I think I'll mount it as close to the tank as possible and use 10mmid rubber line to the filter. I contemplate to drill the banjos a bit to get more flow. <br><br>Would it be of any advantage to replace the stock hardline from the filter to the inj. pump with a rubber line? <br><br>TIA<br><br>AlpineRAM

 

This is gonna be long, but you'll get good info from it.<br><br>Yes the larger fuel line is definitely a smarter thing to to as you may have problems with the Holley eventually because of the flow problems. I tried replacing mine with a rubber line, 3/8. but screwed up royally when doing it. :'( The reason was I could not find the metric fitting that is required to fit into the fuel filter housing and the injector pump. The fittings I was able to find locally had a single .170 hole in them and this is effectively smaller than the banjo bolts because even though they have .130 holes, there are 4 of them around the circumference of the banjo bolt. <br><br>I now know what fittings are needed to adapt it to something commonly available in the US. Since you are in Europe, and Europe LOVES the metric system, you may have easier luck on your end. The filter housing, and injector pump fittings are 12mmx1.50.<br><br>I also replace the line from the tank to the pump with 3/8. I don't know where you are planning to mount yours, but I mounted mine immediately in front of the tank and that also bit me from behind. I did not have enough room to go straight into the fuel pump and couldn't even do a good elbow because it was so tight. I had to loop the hose around to come in from the bottom.<br><br>All of these mistakes I made trying to do this convinced me that it would be wiser in the long run to just buy some hoses for this. You can build your own through Summit Racing, but I chose to not mess with tracking down all of the pieces and got SmokinDiesel.com to make me up some.<br><br>The fittings on the fuel pump are 5/8-18, and are straight thread, not pipe thread, if it's like my Holley Blue. This means if you do not get the fitting in the box, you must get fittings that use an O-ring or washer to seal in the pump.<br><br>I don't know if you have seen the posts from Push_Rod, but he has been recommending the Holley Black fuel pumps and the last several he has dealt with have been bad. It seems that Holley had a bad run on them. Bad enough that Rod does not recommend them anymmore. You may want to bench check your Holley before you go mounting it to anything. Contact Rod for more info on what to check.<br><br>Let me know if you need more of the knowledge I have gained in this experience.<br> ;D<br><br>Chris

 

Since the Holley was the only pump availlable within less than 3 weeks I had to go this way. I didn't receive it yet. If I had ordered the stuff from Wildcat or any other supplier in the US I'd hve to wait about 3-5 weeks because of customs. I'll try to document the install and will post results. <br>Since I'll use a relay for the pump I think I'll install a primer switch for fuel filter exchange. Just turn on the key and switch on the pump. <br><br>I use the relay because I found out that the signal quality on the APPS output of the PCM is decreased due to the pulses from the pump.<br><br>AlpineRAM

 

Yep, install is done. Holley blue pump. 2 3/8th fittings on the pump ( straight, some feet of 10 mm fuel hose, some wireties, some cable ( for the pump ) 2 rubber blocks and voila!

Pump sits snugly in the frame, no kinks in the rubber fuel line.

On the fuel filter I cut off the hard line on the intake so that a vertical piece of about 3&quot; remained, slid the fuel hose over it, 2 clamps and ready to go.

Total time about 30 minutes.

17,5 psi idle, 16 WOT.

Not quite the way I would have done it, but if it don't leak, you got pressure, and you're happy it, that's all that counts. <br><br>Chris

 

Be sure and give us updates occasionaly, 16 psi WOT sounds very nice! Nice job.

 

Stamey: What would you have done differently? Where do you see the downsides of my install? <br>I would like to have any info, because I'd love to have a reliable system. <br><br>TXRam: I measured pressure on the test port on the filter outlet. I did flare all the banjo bolts some time ago. This helped a lot for my WOT pressure. If it wasn't such a PIA to order from the US I'd have gone with soem hi-flow banjos from Wildcat. <br><br>TIA<br><br>AlpineRAM

 

Got the first 1000 km ( about 600 miles) on it.<br><br>It is tight and has good pressure. No difference since install. Pump is audible, but not too loud. <br><br>AlpineRAM

 

I don't want to bad mouth it because there's usually several ways to do something that end up satisfactory. I would not have cut any factory line and eliminated the banjo bolts. Maybe this is in your plan and I just don't know it.<br><br>I have mine planned so that if necessary, I can go back to the old fuel system in an emercency, since my lift pump is good (yeah, I know it might not be by the time I need it, but what can you do?). Now I realize that most people have no plans for this, and that's fine if it's the way you want to go. I can be weirdly **** like that sometimes.<br><br>My biggest concern with the way you said you did it is the banjo bolts, both on the filter housing and the injector pump.<br>But as I said, if you are happy, that's all that counts. ;D<br><br>Chris

 

Stamey- I didn't read it as a badmouthing my solution- just wanted to know what could be done better than I did and whether tis is affordable or not. <br>Since I do not have any DC dealer within the next 1000 miles I have no concerns about warranty. If a part fails I've got to manage the acquisition of something that will work at all on my own. <br>I am not too concerned about the banjo bolts since I've got 2 spares. <br>The part I disliked about the stock system is the massive restriction at high flow rates. Therefore I mounted straight 3/8&quot; fittings on the pump close to the tank and a 10mm ID rubber line to the filter. I didn't change the line from the filter to the VP44 yet, just used the flared bolts. <br><br>AlpineRAM
