I have been reading a lot of comments on this board about heat seeming to be a major influence on killing injector pumps.

Has anyone tried to put a plenum at the front bumper beside the fog lights and use a hose of some kind to direct cooler air directly onto the electronics package on the injector pump?

Do you guys think it would help?

How would you do it, and what materials would you use, Why?

Also, I recently found a supplier of B10. If I am using B10 do I still need to use Power Service?

Thanks in advance.

I think you could could a water block meant to cool a hard drive and plumb it into your cooling system in order to watercool your vp44.



Or maybe a simple heat sink:


Its just a matter of finding one thats the right side. These are made to cool electricics

Im no expert in any way but I was always under the impression that low lift pump pressure to the injection pump caused the pump to fail because it didn't have enough fuel pressure/volume to lube the pump and feed the injectors from the increased amount of fuel we are putting to these engines.

The problem is that fuel cools the VP-44, low FP reduces cooling, causing the electronics to go die. Heat aggravates the problem.

I love my 12v...

Does anyone know how hot the fuel gets in the tank after
several hours of driving, would a fuel cooler
help , maybe on the return line to the tank?

I notice a drop in idle fuel pressure after driving several hours..

I'm mearly suggesting that equiptment made to cool electronics could be used on the vp44's electronics to *assist* in cooling.

The new pumps are coming with improved electronics but there's no way a heatsink is going to hurt a vp and it might very well help =P

A heat sink if anything would help the VP cool. I think a fuel cooler would work with a VP and do it good too. I don't recall what the pump is on an N14 Celect or an ISM but I've worked on a few freightshakers that had fuel coolers on the electronic cummins engines and they never had many problems with their pumps.

Yeah a fuel cooler on the return line or the intake line maybe, not sure how well that would work with it sucking fuel through it and defenitly helps having your tank full of fuel to help it disapate the heat.

I plumbed a 6x8 cooler into the input line between the filter and VP. Never had any problems with flow or pressure. I also reconfigured the in tank module to dump hot fuel away from the fuel pick up line. The stock configuration dumbs hot fuel directly on top of the pick up. There's a great thread on one of the other boards about this. The guy put a heat shield between the block and pump and ran 4" duct with a fan. The fan runs for x # of minutes after shut down to keep it protected from heat soak. The temp test showed the VP area to be just a few degrees above ambient.

Can't remember if it was DTT or not, but someone was working on a heatsink for the VP.
