Over the last week I've been upgrading the fuel delivery from the tank to filter.
It comprises:
10mm fuel line including pick up.
A low pressure piston pump 12v by Facet.
A gauge on the filter housing.
Doing the pickup was the worst part. I had to bend some tube exactly the right shape, then braze it in to the tank adaptor.
Fiddly and the tank had to come out.
I needed to increase the flow of fuel and this mod currently improves power and hot starting.
The pump isn't really up to the task and does lag at full load. The gauge also shows it will be at 1 or 2psi
at idle but under accelaration, the psi will go into negative. So, there's a some vacuum from the pull from the IP lift vane-pump.
The fuel is noticeably heavier though the van will run fine on it, it does eventually starve the IP.
Ok, so I need a bigger volume pump. 12V and means of regulating the pressure or self regulating.
A few PSI is all it'd need and it wants to be at a positive reading at all times.
What's working out for others as a reliable unit for a pusher style of pump? Logically, I'm thinking gear or vane because
I'm pumping oil that's heavier than diesel and that's significantly more viscous than petrol as well!
I'll do a forum search after I post this...
Thanks
