TD42 Compression Test Results Query Please Team

You can get other pumps that will allow fuel to be sucked through them if they stop. As Mark mentioned, the Carter needs a bypass check valve in the setup so the IP can suck fuel around it in case it stops working.

Thanks Gents, Appreciated

Fast easy installation time might be of my greatest issue at the moment, although in saying that NT has its borders closed currently throwing a spanner in our work plans

I’ve done a little bit of a McGoogle search on others and are getting a bit lost on some of the features, some with pressure relief, some without and also relays maybe needed on some too?

Have found a Holley chart that appears to have 3 Mighty Mite models for diesel application that list allowing flow to pass through if they fail.

Some Legends out there over on P4x4 appear to highly rate the Holley Red’s on their TD42’s and it looks like I may be able to get one from SCA down in Lilydale although they appear to be spec’d as Gasoline models which has me even more confused now

I don't think the gasoline spec matters. The Carters are gasoline pumps. My petrol subtank pump transfers the diesel no problem.
Any decent pump will need to be run through a relay anyway.

It would be interesting to see how quiet the Holley pump is. The 4600 I have can be heard easily when standing next to it or behind the car. it doesn't really concern me just a thought really.

The differences may be in the seal materials. I use Aeroflow and they are sold specifically for petrol and then diesel applications. Have not had a problem with mine in 5 yrs use.

You want a pump that has high flow and 6-14psi of pressure. So anything like has been suggested, carter 4600 or 4601, Holly red etc etc. All these suggested ones will work with most fuels. Apart from when using special fuels like nitro and methanol etc most pumps will easily do petrol or diesel.

Thanks Again Gents, Really Appreciated

Just zipped over the hills to VPW in Epping to pickup a Holley Red but was informed they unfortunately would not warranty it used for a diesel application
Ended up purchasing the biggest of the 3 models Holley Mighty Mite (12-428) with 7-10psi /34 Gal./hr capability Gasoline/Diesel. Has vacuum pull through ability if it fails and was $88 inc GST, hope it holds up but warranty said given

How much did VPW sting you for that? interesting too, the 4600 is 100gph and the Holley is 34. But the Carter has 1-2 (circa) psi less. Wonder if this makes any difference to ye'old TD42?

It will if the engines gets lent on. The holley may not produce enough volume. It will be enough for the current application. For a warmed over TD I would use a carter 4601.

$88 inc GST Mudski Mate and I’m only hoping for it to take some pressure off the poor old IP for this trip. Just need it to get me there and back and I’ll look to getting IP rebuilt when coin permits
