Benefits of an inline fuel pump

[myke_w]

I wonder how it'd hold up to biodiesel. Bio likes to eat anything made from natural rubber (although not viton or most plastics).

I think it would withstand biodiesel with no problem, mine has held up just fine, and according to the mfgr
"Fuel Compatibility: No rubber diaphragms or valves to
swell or deteriorate in alcohol blended fuels. Compatible
with leaded and unleaded gasoline, diesel fuel, blended
alcohol fuels, and fuel additives."

Would you mount it back by the tank or up front to "pull" the fuel into the IP?

Per the mfgr "For best results, mount the pump close to the fluid or fuel tank and below the liquid level."  

This pump (like almost any other) pushes fuel, it does not pull it, there are very few pumps that can achieve a prime from a dry line. That would be called a lift pump,(one that can pull enough vacuum on air to move liquid) which is exactly what the lift portion of an injection pump is.

i have one of those pumps, i use it for the nitrous setup on my bike because of the whole gravity fed carbs.. they work great!

if you mount the inline pump, just power it off the injection pump solenoid circuit. . that way whenever the engine is running the pump is runinng.

[myke_w]

I'd suggest fusing it and running it off a switched relay direct from the battery, just in case it draws more amps than the pump solenoid was intended to use..

I've heard also having it powered by the glow relay can help starting.

wow that looks great

so it will smooth out the idle, help cold starts, & have more fuel delivery at higher rpms for just $50. i think you better find a distributer

Not sure exactly, Never ripped one down.. but they are damn good.. I might be wrong about no moving parts... definitely no electronic motor though..

Here's the datasheet

Here's a pic if interested:

i used to work on all kinds of engines and equipment
we need  a pump bigger than one of those,,it wont flow enough
and ive had those fail quite a bit actually
they end up still ticking/making pumping noises,but wont pump fuel...
i used the next bigger one that looks like a can,it still didnt give positive pressure
use a cis pump with a bypass regulator

[nkb]

fail quite a bit?? like is that under constant use? if these are failure prone im gonna dump it fast for next bike season, at 300 for a set of pistons and cylinders that are no longer avaliable
i don't want to depend on some crap pump!! i just liked it cuz it was small and has little draw on my electrical

I'll be a Canadian distributer

This is probably exactly what my car needs to get rid of the stupid air bubbles

Looks like these will only be good for 1 Canadian winter
"• Corrosion Resistant over 100 hours of salt spry"

I can also get 6psi ones if flow is an issue.  Personally I've had no issues with my pump, or any I've installed to aid failing lift pumps on customers cars.. but I'm only one data point. All I know is that these are better than similarly priced motor driven pumps.

[jtanguay]

well any pump is better than no pump... as long as its reliable.

[RabbitGTDguy]

any pump is better than no pump...

I at first opted for a Holley Blue pump but didn't like how high the pressure was (open flow...14psi)... so I went down to the Holley Red pump which is 7psi and it does the job quite nicely. A little more rubber insulation to keep it from making any contact at the mounting point and I'll even be happy with its sound. I may try and relocate it to the upper inside of the p. side fenderwell...we'll see. To clean things up a bit...

I have a facet pump on my 72 Westy w/ 2.0 TypIV motor w/ dual 36mm Dells and I'll be replacing it in favor of the holley style pump this winter. It periodically decided not too work this summer and caused the first ever issues I've had on the TypII

A pic...
you can kinda see the holley red in this pic (far left-hand side) ... like I said...hopefully moving the filter (maybe upgrade the filter too)  as well as the pump this winter...

$30

[lacolocho]

i've mostly heard it recommended to put them up front before the fuel filter

here's another one for $55:

i think some failures of these pumps could be related to wiring... i've had times where i had a solenoid not work and just because the button i used didn't flow enough power...  i think these little pumps are possibly more power hungry than advertised..
